The gradient echo pulse sequence is the simplest type of MRI sequence.
The major purposes behind the gradient technique is a significant reduction in scan time. Small variable flip angle are employed , usually less than 90 degrees. which in turn allow very short repetition time thus decreasing the scan time.
Gradient echo pulse sequence differ from spin echo pulse sequence . There is no 180 degree pulse in GRE. T2 relaxation in GRE is called as T2* relaxation. Gradient can be used to either dephase or rephase the magnetic moments of nuclei.
MRI spin echo sequences are a fundamental imaging technique in magnetic resonance imaging (MRI). They work by manipulating the spin of hydrogen nuclei in the body's tissues to create detailed images. In a spin echo sequence: Spin echo sequences are versatile and used in various MRI applications, including anatomical imaging, quantitative measurements, and lesion characterization. They can produce T1-weighted and T2-weighted images, depending on the specific sequence parameters chosen, offering valuable diagnostic information in medical imaging.

We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

CT fluoroscopy combines the cross-sectional image targeting provided
by CT with the real-time imaging, tracking and movement perception of
fluoroscopy for interventional procedures. It allows continuous update of
images at a fixed position and is commonly used for CT-guided biopsies
and fluid drainages.
Computed tomography (CT) fluoroscopy combines the conventional
advantages of both CT and fluoroscopy and has an important role in
image-guided interventions where real-time imaging is required.
REF: https://doi.org/10.53347/rID-62860
4. The first scanner with CT fluoroscopic capability was developed in 1993
by Dr. Katada
FDA approved the use of CTF in 1995.
Since its introduction , real time CT has been used for optimization of
scan timing in contrast studies, as well as for guidance in biopsy or
drainage procedures.

7. • CT fluoroscopy can be an excellent tool for reducing radiation
dose and saving time on fluoroscopy procedures
• It also provides substantial dose reduction over conventional
CT guidance for procedures like lesion biopsy and drainage.

• Activation of touch interface panel
• Setting the couch speed and gantry position
• Setting the target
• Move in / Move out
• Activate laser
• Scan
• Fine Tuning with joystick
• Image or series review
15. Fluoroscopy software suite of real time CT is dependent on following
factors :
Fast continuous scanning
Fast image reconstruction
Real time image display
REF:http://www.impactscan.org/slides/ctfluoroscopy/sld005.htm
16. The continuous scanning is possible because of Slip Ring Technology, with
no interscan delay for unwinding of connecting cables.
It thus reduces the scan time also and subsequently helps decrease the patient
dose
SYSTEM REQUIRMENTS :
Slip rings for continuous scanning
Fast tube rotation (1s or less)>>some newer systems have 0.5s rotation
High heat capacity tube to allow extended scanning times if necessary
17. Fast image reconstruction, capable of providing upwards of 6-12 frames per
second .
At any given time, it provides 6 real time images ,that constitute a frame. Like,
for 1 rotation of CT (360°) takes about 1 second, and in every 60° one image
is produced. Therefore six images are produced for one gantry rotation.
After one rotation in one second , the CT performs the second rotation and
produces the seventh real time image. Now, this image is added and the 1st image
is discarded .Thus 6 images or frames are obtained at a time.
Sometimes motion artefacts may be seen on the images and appear as streaks ,
however these do not restrict the visualisation of important structure.
18.
19. The data is collected on a defined matrix size of (256×256), which is then
interpolated to a larger matrix (1024×1024) for better resolution.
Images are subsequently displayed on the monitor kept in the operating room
on the Cine mode with a frame rate of 6-12 per second.
21. Low MillIampher Technique for reduction in radiation dose.
Reduction of procedure time.
Quick Check Method
Real Time Imaging
Dedicated High Speed Array Processor
Potential for increased procedure effeciency and accuracy leading to higher
diagnostics yeild .
22. Overlapping structures can be removed, providing accurate spatial information
Real-time display of images
Consequent reduction in complications through finer needle control
Reduced procedure time
Increased operator confidence
23. Large radiation doses to both patient and operator.
Limited FOV / scanning range.
Poor image quality due to low mA , because of the appearance of noise.
Increased investment in more powerful hardware and specialized software
needed.
24. The Doctor may want to obtain highly accurate imaging
They may wish to provide the patient with shorter intervention time which
may decrease the radiation exposure
Real time view of the body may give the doctor more information to make
better decisions

25. Video monitor will need to be displayed in the scanning room
An operator panel is required in the scanning room – with controls available for table
movement, gantry lift, laser light control and fluoroscopic factors. Exposures will
usually be activated using a footswitch
Involves an x-ray tube current of 30-50 ma
Need for additional beam filtration to decrease patient dose exposure.
Multislice machines have finer z-axis resolution.
CT fluoroscopy requires special techniques for image reconstruction, due to the need for
rapid imaging.

31. • CT fluoroscopy is a recently developed acquisition mode that allows faster
imaging reconstruction, near continuous image update and convenient in room
table control and image viewing during procedure .
• Acceptable radiation dose rate to patient and operator, is user friendly and
guides interventional procedures with rapidity.
• Operators have to adopt techniques that will minimize the risk of putting their
fingers in the beam
