X-Ray
X-rays, also known as X-radiations, are a form of ionizing electromagnetic radiation discovered in 1895 by Wilhelm Röntgen. They have wavelengths between 0.01 to 10 nanometers. X-rays are used widely in medical diagnostics to image bone fractures and other injuries or medical conditions. However, they also carry risks of causing cell damage and cancer due to their ionizing properties. Proper techniques and limited exposure are important to minimize these risks.
Magnetic Resonance Imaging - MRI
This presentation discusees a brief history of the MRI, it's mechanism of action, applications in dentistry and recent advancements in its technology. Also it's advantages and disadvantages in comparison with the CT scan
Basics of CT Scan
CT scans provide detailed cross-sectional images of the body by combining x-rays with computer technology. CT scans are useful for diagnosing many medical conditions by allowing physicians to examine tissues and organs. While CT scans provide valuable medical information with minimal risks, they do involve exposure to radiation, so the benefits must be weighed against the risks for each individual patient's circumstance.
Basic principle of x ray
This document provides an overview of x-rays and x-ray tubes. It discusses the history of x-rays starting with their discovery by Wilhelm Roentgen in 1895. It then covers basic x-ray physics and the electromagnetic spectrum. The document focuses on the components and functioning of x-ray tubes, including the cathode, filament, focusing cup, anode, rotating target, and control console. It explains how varying the kVp and mAs settings on the control console controls the x-ray beam properties.
Basics of Ultrasound
Ultrasound uses high-frequency sound waves to produce images of the inside of the body in real-time without using radiation. It is widely used due to its availability, low cost, speed, and ability to show internal structures and blood flow. Common uses include examining organs like the heart, liver, and kidneys, as well as guiding procedures, imaging breasts and blood vessels, and assessing fetal development in pregnancies. The procedure works by a transducer sending sound waves into the body and receiving echoes to create images based on the return signal.
Fluoroscopy ppt
Fluoroscopy is an imaging technique that uses x-rays to obtain real-time moving images of the internal structures of the body. It allows physicians to see how body parts move and to guide placement of instruments or injection of dye. The fluoroscopy machine takes a continuous stream of x-ray images at a rate of approximately 25-30 images per second which are displayed on a monitor. While it is useful for various medical procedures, fluoroscopy does expose patients to radiation, so the benefits must outweigh the small risk of developing cancer or experiencing burns from prolonged exposure. Precise procedures and consideration of radiation exposure help minimize risks.
Ct scan
Computed tomography (CT) scanning uses X-rays and computer technology to create cross-sectional images of the body. Godfrey Hounsfield invented the first CT scanner in 1971, which used X-rays to image internal organs without having to use invasive procedures. CT scanning provides more detailed images than standard X-rays and can detect many abnormalities, but does expose patients to small amounts of radiation.
Mri final ppt
Magnetic resonance imaging (MRI) uses strong magnets and radio waves to produce detailed images of the inside of the body without using ionizing radiation. An MRI machine contains a powerful magnet to align hydrogen atoms in the body. Radio waves are then used to excite the atoms, which emit signals as they relax. These signals are detected by antennas and used by a computer to generate 2D or 3D images of tissues and organs. MRI provides excellent soft tissue contrast and is useful for imaging the brain, muscles, joints, and other internal organs. While it has advantages over CT in avoiding radiation, MRI scans can be costly and some patients may find the enclosed scanner space claustrophobic.

Introduction to mri
Dr. Rajesh Venunath Nair teaches radiology at K.S Hegde Medical Academy in Mangalore. His presentation discusses the history, basic principles, hardware, imaging sequences, and clinical applications of magnetic resonance imaging (MRI). It explains how MRI uses radiofrequency pulses and magnetic fields to produce detailed images of internal organs and soft tissues without using ionizing radiation. The presentation covers the main components of MRI scanners, different pulse sequences, tissue contrast mechanisms, use of contrast agents, safety considerations, and recent technical advances that have expanded clinical use of MRI.
Basics of MRI
MRI uses magnetic fields and radio waves to produce detailed images of organs and tissues in the body. It is commonly used to evaluate the chest, abdomen, pelvis, and breasts to diagnose conditions like tumors, heart problems, and liver or kidney diseases. During an MRI exam, the patient lies still inside the machine while images are taken. MRI has benefits over other tests as it does not use radiation and can clearly depict soft tissues, though movement can cause blurred images and certain implants are not compatible.

The document summarizes the components and functioning of a fluoroscope. A fluoroscope uses x-rays to visualize the motion of internal structures in real-time. It consists of an x-ray generator, tube, collimator, filters, table, grid, image intensifier, optical coupling and television system. The image intensifier converts x-rays into light photons, which are converted into an electronic signal via a television camera or CCD and displayed on a monitor. Spot films can also be obtained from fluoroscopy for later examination.
Ct scan final (2)
This document provides an overview of computed tomography (CT) scanning. It discusses the history and invention of CT, its common uses in medicine, working principles including components like the gantry and detectors, generations of CT technology, and the mathematical principles behind image reconstruction. CT scanning uses X-rays and computers to produce cross-sectional images of the body and has become an important medical imaging tool since its invention in the 1970s.
CT - computed tomography
Computed tomography (CT) uses X-rays and digital geometry processing to generate 3D images of the inside of the body. During a CT scan, an X-ray tube rotates around the patient, emitting beams that are detected and used to construct cross-sectional slices. A radiologist can then analyze these slices to diagnose medical conditions by viewing internal organs, bones, soft tissues, and blood vessels with greater clarity and detail than traditional X-rays. CT scans are commonly used to diagnose cancers, cardiovascular diseases, infections, appendicitis, trauma, and muscular-skeletal disorders.
Ultrasonography
Ultrasonography uses high-frequency sound waves and a transducer probe to produce images of the inside of the body. It is widely used due to its availability, speed, low cost, and the fact that it does not use radiation. Ultrasound can be used to evaluate symptoms, guide procedures like biopsies, and examine internal organs. It is commonly used in obstetrics to assess pregnancies and in gynecology to examine reproductive organs. The procedure involves applying gel and moving a transducer probe over the body to obtain images, which are displayed on a machine with components like a transducer, CPU, and display. Benefits include being non-invasive and providing real-time images, while limitations include
Mri ppt
MRI uses magnetism and radio waves to produce detailed images of soft tissues in the body. It was developed based on principles of nuclear magnetic resonance and the first MRI exam took 5 hours to produce one image. Key components of an MRI scanner include powerful magnets to align hydrogen nuclei in tissues, gradient coils to localize images, and radiofrequency coils to transmit signals and receive returning signals used to construct images. MRI provides advantages over other imaging techniques by using no ionizing radiation and allowing cross-sectional imaging in any plane with good contrast resolution.
Angiography
Angiography is a medical imaging technique that uses radiography to visualize blood vessels and organs after injecting a contrast medium. It can detect diseases of the arteries and veins like atherosclerosis, aneurysms, and internal bleeding. The procedure involves a team inserting a catheter into the blood vessels and injecting iodinated contrast dye before capturing x-ray images. Risks are generally low but can include minor bleeding, vessel damage, and allergic reactions to the contrast medium. Advances in digital subtraction angiography now make angiography the gold standard for assessing vascular diseases when other imaging modalities are inconclusive.
Computed tomography
The document discusses computed tomography (CT) scanning. It begins by introducing CT and comparing it to conventional radiography. CT provides more accurate diagnostic information by reconstructing 3D structures from multiple 2D projections, unlike conventional radiography which produces 2D shadow images. The document then covers key aspects of CT scanning including the components involved in data acquisition, the reconstruction process, and parameters such as slice thickness and radiation dose. It also describes advances in CT technology over generations from narrow single detector scans to current multi-detector scanners.
Mammography
Mammography uses low-dose x-rays to examine the breast for early cancer detection. It has advanced from film to digital mammography and tomosynthesis, which creates 3D breast images. Computer-aided detection highlights abnormal areas. Screening mammograms aim to detect cancer in asymptomatic women, while diagnostic mammograms investigate symptoms. Benefits include early detection, but limitations include false positives and negatives due to breast density. Yearly mammograms after age 40 are recommended for breast cancer screening. Ultrasound provides localized breast images without radiation but cannot screen whole breasts. MRI is superior for dense breasts but has no radiation risk.

X ray ppt
X-rays are a form of electromagnetic radiation that can pass through the body and be used to produce images of internal structures. An x-ray machine sends individual x-ray particles through the body using an x-ray tube, and the images are then recorded digitally. The key components of an x-ray machine include the x-ray tube, transformer, and control panel.
Ultrasonography
Ultrasonography uses high frequency sound waves to visualize structures inside the body. It has several applications in dentistry and oral/maxillofacial imaging. USG can detect fractures, lesions, salivary stones, and blood flow. The piezoelectric transducer converts electrical pulses into ultrasonic waves, which reflect off tissues. Differences in tissue impedance allow visualization of structures. Doppler ultrasonography assesses blood flow direction/velocity. USG provides a low-cost, non-invasive way to diagnose and monitor conditions of the oral cavity, jaws, and salivary glands.
Ultrasound imaging
Ultrasound uses high frequency sound waves to visualize internal structures. It works by transmitting sound waves into the body using a transducer probe, which detects the echoes as they bounce off tissues and organs. The echoes are processed to form images on the ultrasound machine screen in real-time. Common applications include obstetrics, cardiology, and urology. The Philips HD11 is an ultrasound system with curvilinear, linear, and phased array probes for different exams. It provides grey scale, Doppler, and color imaging modes. Ultrasound has benefits of being non-invasive, portable, and having no radiation, but has limitations of being operator dependent and unable to penetrate bone.

X Rays Ppt
The document discusses x-rays, how they produce images, and their risks and benefits. It explains that x-rays are electromagnetic waves that can pass through tissues at different levels, exposing film to create internal images of the body. German physicist Wilhelm Röntgen discovered x-rays in 1895 while experimenting with vacuum tubes. Lead shields are used during x-rays to block radiation and prevent long-term exposure, as x-rays can detect health problems. The document identifies different bones and joints visible in sample x-ray images.
X ray tube
The document discusses the components and functioning of an X-ray tube. The key components are the glass envelope, cathode, and anode. Electrons are emitted from the cathode filament and accelerated toward the anode, where their impact produces X-rays. The rotating anode allows for greater heat dissipation to enable higher exposures. Factors like focal spot size and the anode heel effect determine the quality and characteristics of the emitted X-rays. Proper cooling and protective housing are also important for safe tube operation.

X ray physics part I
Wilhelm Conrad Röentgen was a German physicist who discovered x-rays in 1895. He was awarded the first Nobel Prize in Physics in 1901 for his discovery. Röentgen discovered x-rays accidentally while experimenting with cathode ray tubes. He noticed a fluorescent glow coming from a nearby screen and realized some new type of radiation was causing this. When he placed his wife's hand on photographic plates and exposed them to this radiation, the outline of bones in her hand appeared on the developed plate. This led him to name this new type of radiation "x-rays".
X ray machine-new
X-rays are a form of electromagnetic radiation with wavelengths between 0.01 to 10 nanometers that can penetrate some materials like soft tissue. The three main components of an x-ray machine are the vacuum tube, high voltage power source, and operating console. X-rays are produced when electrons are accelerated toward a metal target in the vacuum tube. They are used medically for diagnostic imaging like radiography and mammograms due to their non-invasive nature, though overexposure can increase cancer risk.
Introduction to the parts of x ray machine
The document describes the key components of an X-ray machine:
1. The X-ray tube which produces X-rays and contains a cathode and anode in a vacuum tube housed in a protective casing.
2. The operating console which controls the voltage, current, and exposure time of the X-ray tube.
3. Additional components include a high voltage transformer, collimator to control the beam, patient table, grid to reduce scattering, and Bucky device which holds the X-ray film.
X rays
X-rays are a form of electromagnetic radiation that can penetrate materials and are used in medical imaging to see inside the body. Wilhelm Röntgen discovered X-rays in 1895 while experimenting with cathode ray tubes. He noticed a fluorescent screen glowing nearby even when covered, and realized the rays could pass through some materials but not others like bone. This allowed him to see the outline of bones in his hand, demonstrating their medical application. Today, X-rays are widely used in medicine, industry, and research due to their ability to penetrate soft tissue while being blocked by denser materials like bones and metals.
Xray film & film processing
The document discusses X-ray film, its characteristics, composition, and processing. It can be summarized as follows:
X-ray film contains a radiation-sensitive emulsion coated on a transparent base. The emulsion contains light-sensitive silver halide crystals suspended in gelatin. When exposed to X-rays, the crystals form a latent image which is chemically developed to create the visible image. Development converts the latent image into metallic silver through a redox reaction using developer chemicals. The film then undergoes fixing and washing to remove unexposed silver halide.
X ray films
The document discusses x-ray films and the process of developing radiographic images. It describes the composition of intraoral x-ray films, including the film base, emulsion, and packet components. It then explains the processes of latent image formation when film is exposed to x-rays and the chemical steps to develop the latent image, including developing, fixing, washing and drying the film. Finally, it discusses factors that influence radiographic image quality such as density, contrast and sharpness.

Cell Therapy Expansion and Challenges in Autoimmune Disease
There is increasing confidence that cell therapies will soon play a role in the treatment of autoimmune disorders, but the extent of this impact remains to be seen. Early readouts on autologous CAR-Ts in lupus are encouraging, but manufacturing and cost limitations are likely to restrict access to highly refractory patients. Allogeneic CAR-Ts have the potential to broaden access to earlier lines of treatment due to their inherent cost benefits, however they will need to demonstrate comparable or improved efficacy to established modalities.
In addition to infrastructure and capacity constraints, CAR-Ts face a very different risk-benefit dynamic in autoimmune compared to oncology, highlighting the need for tolerable therapies with low adverse event risk. CAR-NK and Treg-based therapies are also being developed in certain autoimmune disorders and may demonstrate favorable safety profiles. Several novel non-cell therapies such as bispecific antibodies, nanobodies, and RNAi drugs, may also offer future alternative competitive solutions with variable value propositions.
Widespread adoption of cell therapies will not only require strong efficacy and safety data, but also adapted pricing and access strategies. At oncology-based price points, CAR-Ts are unlikely to achieve broad market access in autoimmune disorders, with eligible patient populations that are potentially orders of magnitude greater than the number of currently addressable cancer patients. Developers have made strides towards reducing cell therapy COGS while improving manufacturing efficiency, but payors will inevitably restrict access until more sustainable pricing is achieved.
Despite these headwinds, industry leaders and investors remain confident that cell therapies are poised to address significant unmet need in patients suffering from autoimmune disorders. However, the extent of this impact on the treatment landscape remains to be seen, as the industry rapidly approaches an inflection point.

Breast cancer: Post menopausal endocrine therapy
Breast cancer in postmenopausal women with hormone receptor-positive (HR+) status is a common and complex condition that necessitates a multifaceted approach to management. HR+ breast cancer means that the cancer cells grow in response to hormones such as estrogen and progesterone. This subtype is prevalent among postmenopausal women and typically exhibits a more indolent course compared to other forms of breast cancer, which allows for a variety of treatment options.
Diagnosis and Staging
The diagnosis of HR+ breast cancer begins with clinical evaluation, imaging, and biopsy. Imaging modalities such as mammography, ultrasound, and MRI help in assessing the extent of the disease. Histopathological examination and immunohistochemical staining of the biopsy sample confirm the diagnosis and hormone receptor status by identifying the presence of estrogen receptors (ER) and progesterone receptors (PR) on the tumor cells.
Staging involves determining the size of the tumor (T), the involvement of regional lymph nodes (N), and the presence of distant metastasis (M). The American Joint Committee on Cancer (AJCC) staging system is commonly used. Accurate staging is critical as it guides treatment decisions.
Treatment Options
Endocrine Therapy
Endocrine therapy is the cornerstone of treatment for HR+ breast cancer in postmenopausal women. The primary goal is to reduce the levels of estrogen or block its effects on cancer cells. Commonly used agents include:
Selective Estrogen Receptor Modulators (SERMs): Tamoxifen is a SERM that binds to estrogen receptors, blocking estrogen from stimulating breast cancer cells. It is effective but may have side effects such as increased risk of endometrial cancer and thromboembolic events.
Aromatase Inhibitors (AIs): These drugs, including anastrozole, letrozole, and exemestane, lower estrogen levels by inhibiting the aromatase enzyme, which converts androgens to estrogen in peripheral tissues. AIs are generally preferred in postmenopausal women due to their efficacy and safety profile compared to tamoxifen.
Selective Estrogen Receptor Downregulators (SERDs): Fulvestrant is a SERD that degrades estrogen receptors and is used in cases where resistance to other endocrine therapies develops.
Combination Therapies
Combining endocrine therapy with other treatments enhances efficacy. Examples include:
Endocrine Therapy with CDK4/6 Inhibitors: Palbociclib, ribociclib, and abemaciclib are CDK4/6 inhibitors that, when combined with endocrine therapy, significantly improve progression-free survival in advanced HR+ breast cancer.
Endocrine Therapy with mTOR Inhibitors: Everolimus, an mTOR inhibitor, can be added to endocrine therapy for patients who have developed resistance to aromatase inhibitors.
Chemotherapy
Chemotherapy is generally reserved for patients with high-risk features, such as large tumor size, high-grade histology, or extensive lymph node involvement. Regimens often include anthracyclines and taxanes.
