A Complete Guide to PET CT Scan

A PET-CT (Positron Emission Tomography-Computed Tomography) scan is a medical imaging technique that combines two powerful imaging technologies to create detailed images of the body.

A PET-CT (Positron Emission Tomography-Computed Tomography) scan is a medical imaging technique that combines two powerful imaging technologies to create detailed images of the body.

During the PET scan, a small amount of radioactive tracer) contrast is injected into the patient's body. This tracer emits positrons, which are picked up by a PET scanner and used to create detailed 3D images of the body's tissues and organs.

The CT scan uses X-Rays to produce detailed cross-section images of the body. By combining the images produced by both PET scans and CT scans, doctors can better visualize the location, size, and metabolic activity of abnormal tissues in the body, such as cancerous tumors.

The PET CT Scan is commonly used in the diagnosis, staging, and treatment planning of various cancers, including lung cancer, breast cancer, and colorectal cancer. They can also be used to detect heart disease, brain disorders, and other conditions.

What are the uses of PET CT scans?

PET scans are a valuable tool in medicine, but they are typically used in conjunction with other diagnostic tests and medical evaluations. The specific use of PET scans will depend on the medical condition being evaluated and the information the healthcare provider is seeking.

Cancer Diagnosis: Whole Body PET scan can help detect the presence and location of cancer in the body. It can also help in evaluating the size, spread of the cancer and guide treatment planning.

Cancer Treatment Planning:  PET scans can help determine and monitor the response of the best course of treatment for cancer disease. Such as radiation therapy, chemotherapy, etc.

Heart Disease: Cardiac PET scan can help diagnose and evaluate heart disease by assessing blood flow to the heart and the function of the heart muscle.

Brain Disorders: Brain PET scans can help diagnose and evaluate brain disorders such as Alzheimer's disease, Parkinson's disease, and epilepsy.

Infectious Disease: PET scans can be used to diagnose and monitor infectious diseases such as HIV, Tuberculosis, and certain types of pneumonia.

Other conditions: PET scans can also be used to diagnose and monitor other conditions such as thyroid disorders, gastrointestinal disorders, and bone disorders.

What is the Procedure for PET Scan?

Preparation: Before the scan, the patient may be instructed to avoid food and drink for several hours and strenuous physical activity for some time. The patient may also be asked to avoid certain medications and to drink plenty of fluids.

Tracer Injection: A small amount of radioactive tracer is injected into the patient's bloodstream, usually through a vein in the arm. The tracer typically takes about 30-60 mins to distribute throughout the body.

Imaging: The patient is positioned on a flat table that slides into the PET scanner. The scanner detects the radioactive tracer and uses it to create detailed images of the body. The patient may need to remain still during the scan, which typically takes 30 to 60 minutes.

Post Scan: After the scan, the patient may be asked to drink fluids to flush the tracer out of their body. The patient can typically resume normal activities immediately after the scan.

It's important to note that PET scans involve a small amount of radiation exposure, but the benefits of the test typically outweigh the risks. Patients should discuss any concerns they have about the procedure with their healthcare provider.
