网页Doctors perform PET and PET/CT scans to: detect cancer and/or make a diagnosis. determine whether a cancer has spread in the body. assess the effectiveness of treatment. determine if a cancer has returned after treatment. evaluate prognosis. assess tissue metabolism and viability.
Positron emission tomography scan - Mayo Clinic
网页A positron emission tomography (PET) scan is an imaging test that can help reveal the metabolic or biochemical function of your tissues and organs. The PET scan uses a radioactive drug called a tracer to show both typical and atypical metabolic activity.
PET-CT - Wikipedia
网页Positron emission tomography–computed tomography (better known as PET-CT or PET/CT) is a nuclear medicine technique which combines, in a single gantry, a positron emission tomography (PET) scanner and an x-ray computed tomography (CT) scanner, to acquire sequential images from both devices in the same session, which are combined …
PET/CT scan for cancer - Cancer Treatment Centers of America
网页2021年10月29日 · A positron emission tomography (PET) scan is an advanced nuclear imaging technique used to look for cancer and its spread. PET scanners trace a form of radioactive sugar as it’s absorbed by the body's cells. Because cancer cells grow quickly, they take up larger amounts of sugar (glucose) than normal cells.
PET Scan: What It Is, Types, Purpose, Procedure & Results
网页A positron emission tomography (PET) scan is an imaging test that produces images of your organs and tissues at work. The test uses a safe, injectable radioactive chemical called a radiotracer and a device called a PET scanner.
PET/CT Scan: How to Prepare, What to Expect & Safety Tips
网页Positron emission tomography, also called PET imaging or a PET scan, is a diagnostic examination that involves getting images of the body based on the detection of radiation from the emission of positrons. Positrons are tiny particles emitted from a radioactive substance administered to the patient.
PET Scan: Definition, Purpose, Procedure, and Results
网页2021年12月16日 · A positron emission tomography (PET) scan is an imaging test that uses a special dye with radioactive tracers. Learn why it’s performed and how to prepare.
