- 1 They are used alongside X-rays or MRI (magnetic resonance imaging) scan to diagnose or provide more insight into a condition. 2  PET scans are often used to investigate the following conditions: epilepsy, Alzheimer's disease, cancer, heart disease.  A CT or MRI scan examines the size and shape of body organs and tissue.

Tumor Quantification in Clinical Positron Emission Tomography Positron emission tomography (PET) is used extensively in clinical oncology for tumor detection, staging and therapy response assessment. Quantitative measurements of tumor uptake, usually in the form of standardized uptake values (SUVs), have enhanced or replaced qualitative interpretation. In this paper we review the current status of tumor quantification methods and their applications to clinical oncology.

Positron Emission Tomography (PET) A PET scan of the heart is a noninvasive nuclear imaging test. It uses radioactive tracers (called radionuclides) to produce pictures of your heart. Doctors use cardiac PET scans to diagnose coronary artery disease (CAD) and damage due to a heart attack.

Frequently Asked Questions What is a PET/CT scan? Positron Emission Tomography (PET) and Computed Tomography (CT) scans are both standard imaging tools that physicians use to pinpoint disease states in the body. A PET scan images the cellular activity of the body at a very early stage, often before anatomical changes take place.

Positron Emission Tomography - Computed Tomography (PET/CT) Positron emission tomography, also called PET imaging or a PET scan, is a type of nuclear medicine imaging. Nuclear medicine is a branch of medical imaging that uses small amounts of radioactive material to diagnose and determine the severity of or treat a variety of diseases, including many types of cancers, heart disease, gastrointestinal, endocrine, neurological disorders and other abnormalities within the body.

Positron Emission Tomography (PET Scan) For example, in PET scans of the brain, a radioactive atom is applied to glucose (blood sugar) to create a radionuclide called fluorodeoxyglucose (FDG), because the brain uses glucose for its metabolism. FDG is widely used in PET scanning.

PET-CT Scan Cost PET-CT scan is a combination of PET scan and CT scan. This is mostly used for the detection of cancer and heart diseases in our body. It is also used in some other cases like epilepsy and alzheimer ’s disease. This is one of the most expensive radiology tests in India. There are total of only 92 PET/CT scan centers in India. Please note that in most of the centers, you would need a doctor's prescription for the test. Get discount upto 45% on PET-CT Scan test in your city.

Cancer PET/CT scans provide information to help physicians: 1  Locate the site of the cancer. 2  Determine the size of the tumor. 3  Differentiate benign from malignant growths.  Discover if the cancer has 1  spread. Select treatments that are likely to be appropriate.  Monitor the success of 1  therapy. Detect any recurrent tumors.

Positron Emission Tomography (PET) A PET scan is a very accurate way to diagnose coronary artery disease and detect areas of low blood flow in the heart. PET can also identify dead tissue and injured tissue that’s still living and functioning. If the tissue is viable, you may benefit from a PCI or coronary artery bypass surgery.

Positron emission tomography Positron-emission tomography (PET) is a nuclear medicine functional imaging technique that is used to observe metabolic processes in the body as an aid to the diagnosis of disease. The system detects pairs of gamma rays emitted indirectly by a positron-emitting radionuclide , which is introduced into the body on a biologically active molecule.

Computed Tomography (CT) Scan Doctors also use PET-CT scans to: 1  Find the right place for a biopsy. 2  Find out if the cancer treatment is working. 3  Evaluate how well treatment worked after it ends.  Plan radiation therapy.

PET (positron emission tomography) scan A positron emission tomography (PET) scan is a type of nuclear imaging test that shows the metabolic activities (energy usage) of your brain. While X-ray, CT, and MRI scans look at the anatomy of your brain, a PET scan can give your doctor information about how your brain is working.

- Positron emission tomography (PET) scanning combined with CTA is on the horizon for the detection of heart disease. PET scans are a form of nuclear medicine -- nuclear being the small dose of radioactive material you are injected with before the test (the radiation exposure is similar to that of a standard X-ray). As with CTA, PET involves a doughnut-like scanning device that takes the images.

PET scan for breast cancer Breast PET scan. A breast positron emission tomography (PET) scan is an imaging test that uses a radioactive substance (called a tracer) to look for breast cancer. This tracer can help identify areas of cancer that an MRI or CT scan may miss. A PET scan requires a small amount of radioactive material (tracer). This tracer is given through a vein (IV), usually on the inside of your elbow. It travels through your blood and collects in organs and tissues. The tracer helps the radiologist see certain areas or diseases more clearly.

Positron Emission Tomography and Computed Tomography (PET-CT) Scans Doctors combine these tests because a CT scan and PET scan show different things. A CT scan shows detailed pictures of tissues and organs inside the body. A PET scan shows abnormal activity. So, the 2 scans together provide more information about the cancer.

Positron Emission Tomography - Computed Tomography (PET/CT) Positron emission tomography (PET) uses small amounts of radioactive materials called radiotracers, a special camera and a computer to help evaluate your organ and tissue functions. By identifying body changes at the cellular level, PET may detect the early onset of disease before it is evident on other imaging tests.
