CT Scan
Millions of Indians experience imaging tests yearly to help doctors diagnose a health condition. For
example, Dr. Manish Singhal , the best cancer doctor in Delhi, says over 80 million CT scans are
performed annually. Imaging methods provide a window to the interior human body without the
need for an incision. This assists keep patients out of the operating room and saves them the risks
and expenses of surgery.
Two naturally ordered tests are CT and PET scans, but they are not the same.
What Is a CT Scan?
A computed tomography (CT) scan is a particular imaging method. A CT scan delivers a detailed 3-D
image of the inside of your body. This scan is often prescribed to check for abnormalities in the
brain, spine, neck, chest, or abdomen. By looking at CT scan images, your doctor can consider hard
tissues, such as your bones, and soft tissues, such as your muscles and organs. This indicates that a
CT scan will show everything from a bone fracture to a tumour.
This allows the Best Oncologist in Noida to check for organ damage, bone fractures, and internal
bleeding.
How Does a CT Scan Work?
A patient usually lies flat on an exam table to experience the procedure. The table will then move
through the CT scan machine as it takes pictures. The scanning method usually takes a few minutes.
Some patients may need to drink a contrast material before the scan, either by consuming the
substance or receiving it intravenously. The contrast is a dye that emphasizes the examined areas
so doctors can see them more clearly.
Although CT scans are a simple, painless method, an oncologist in Delhi aims to perform the scan
fast.
2. What Is a PET Scan?
A positron emission tomography (PET) scan is a form of nuclear medication imaging. A PET scan uses
a small amount of radioactive material called a radiotracer, a camera, and a computer to produce
images of the inside of your body. A PET scan shows a doctor how your cells and body parts work.
PET scans are most generally used to detect or monitor cancer.
How Does a PET Scan Work?
During a PET scan process, Dr. Manish Singhal, the best cancer doctor in Delhi, will inject a small
amount of the radioactive tracer into a patient’s vein, usually on the inside of an elbow. After the
injection, the tracer will move through the body and collect in tissues and organs. Tracers will
manage tumors, inflamed spots, or cancer cells for doctors to see.
After the tracer is soaked, the patient will move to an exam table that slides into a scanner. The PET
scanner will notice the tracer and turn the data into 3-D images on a computer monitor.
What Is the Difference Between a CT and PET Scan?
Possibly the main difference between CT and PET scans is their priority. A CT scan makes a detailed
non-moving image of organs, bones, and tissues. A PET scan, on the other hand, delivers doctors
how the tissues in your body work on a cellular level. Other differences include:
They use different materials: CT scans pass x-rays through the body to produce images. A
PET scan uses a radioactive material that radiates energy. The energy is then detected by a
particular camera to take pictures.
A PET scan is more time-consuming: A CT scan is completed in minutes. This makes it a
perfect tool for doctors to act fast in emergencies. A PET scan could take 20 minutes to
several hours, depending on a patient’s infection. In some cases, the process may be
performed over several days.
Radiation does not stay in the body with a CT scan: After a CT scan, no radiation stays in the
body. Conversely, a small quantity of radiation may remain in the body for a short time after
a PET scan.
PET scans detect cancer earlier than other tests: Unlike other imaging formats, a PET scan
shows molecular activity and helps doctors specify conditions in the earliest stages. CT scans
show symptoms of a problem after a situation changes the form of tissues or organs. For this
reason, a PET scan is a favorably reliable tool for detecting cancer.
How Are PET and CT Scans Similar?
According to the Best Oncologist in Delhi, CT and PET scans focus on different human body
elements and use unique materials, but they still share a lot in common.
Both are usually served at an outpatient facility and do not require a hospital stay.
Both can be utilized to detect cancer.
Both are correct, painless, and noninvasive methods.
Both destroy the need for experimental surgery.
Most significantly, both imaging tests help doctors analyze the cause of a patient’s symptoms. This
allows doctors to treat their patients and help them enjoy healthy lives.
