Learn about the different types of positron emission tomography (PET) scans. Positron emission tomography (PET) is a functional imaging technique that uses radioactive substances known as radiotracers to visualize and measure changes in metabolic processes, and in other physiological activities including blood flow, regional chemical composition, and absorption.Different tracers are used for various imaging purposes, depending on the target process within the body. It can be done along with a CT scan. These scans can help doctors figure out whether a treatment is working for a patient. There are various types of Cat Scans discussed below which will help you in many ways-Abdominal Cat Scan- As a CAT scan or a CT scan gives an elaborate look inyo the body of a human being, it is better than the traditional X-Rays. An injectable radioactive tracer detects diseased cells. In some cases, an initial scan may be performed prior to the injection of the radionuclide, depending on the type of study being done. Positron Emission Tomography (PET) – This scan works on the principle of the difference in metabolic rate between cancer cells and normal cells. PET scan. There are 4 main components a PET scan machine, the gantry (frame) that houses the detection apparatus with a large patient port (opening), the subject table that moves in and out of the patient port allowing for a complete scan, the detector/camera system that captures the image, and a computer system that proce… A positron emission tomography scan is known as a PET scan. Other types of PET scans may focus entirely on one part of the body, often the brain. Positron Emission Tomography (PET) CT Scan. Length of PET scan. What is positron emission tomography (PET)?

It's used to help diagnose some conditions including cancer. It is also possible to use PET scans to determine whether a cancerous growth found in one organ or system has already spread to other parts of the body. PET Scan: PET scans use radioactive drugs (called tracers) and a scanning machine to show how your tissues and organs are functioning. Nuclear scans make pictures based on the body’s chemistry (like metabolism) rather than on physical shapes and forms (as is the case with other imaging tests). For example, if a patient comes in with abdominal pain, we can do a CT scan to determine whether the patient has appendicitis and needs an … Instead, it works by blocking the x-rays.

Positron emission tomography, also called PET imaging or a PET scan, is a type of nuclear medicine imaging. A PET scan is a type of imaging that can show what’s happening in your body. PET Scans (Positron Emission Tomography) and SPECT Scans (Single Photon Emission Computed Tomography) were first used in the 1970's for research. With the exception of those requiring an injection of contrast dye, scans are relatively painless—like getting a picture taken. The PET scan can show how far a cancer has spread or how well it is responding to treatment. Your healthcare provider may perform a PET scan and CT scan at the same time (PET-CT). It is important that you lie still during this process. A PET scan for breast cancer may be used after diagnosis to collect more information about the cancer. Now, some 30 years later, these non-invasive techniques have been adapted to diagnose disease in humans. Learn more aout cardiac PET/SPECT.

Epub 2009 Oct 28. Positron emission tomography (PET) scans detect early signs of cancer, heart disease and brain disorders. PET scans. The PET scan uses a mildly radioactive drug to show up areas of your body where cells are more active than normal. The patient then undergoes a scan of the heart that detects the signal of the tracer and produces a 3D image. PET scan is an imaging technique that uses a radioactive tracer to locate tissue differences at a molecular level. Get the iPhone MyHealth app » Often, you start with an X-ray because it’s a quick way to get basic information. Positron Emission Tomography (PET) is another type of scan that uses radioactive material and a special scanning device to detect neuroendocrine tumors. Unlike CT scans and X-rays, an MRI does not use ionizing radiation that can be potentially harmful. Though the mechanism for creating all PET images is the same no matter what the test is for, introducing radioactive materials into different parts of the body can help doctors closely examine the way a particular organ, including or system is working. Various types of positron emission tomography scans, or PET scans, can be used to evaluate a number of systems in a person’s body. Email .
