PET-CT is a combination of cross-sectional anatomic information provided by CT and the metabolic information provided by positron emission tomography (PET).. PET is most commonly performed with 2-[F-18]fluoro-2-deoxy-D-glucose (FDG). S 18F-fluorodeoxyglucose (FDG) PET/CT is a pivotal imaging modality for cancer imaging, assisting diagnosis, staging of patients with newly diagnosed malignancy, restaging following therapy and surveillance. 63 0 obj Approved tracers are called radiopharmaceuticals since they must meet FDAâs exacting standards for safety and appropriate performance for the approved clinical use.

The PET scan uses a mildly radioactive drug to show up areas of your body where cells are more active than normal. )Tj This combination test produces 3D images that allow for a more accurate diagnosis. Updated the PET Scans section Added the Sonography section FSSA and DXC . NIBIB is currently supporting research to develop a new family of PET imaging contrast agents that are taken up specifically by bacterial cells, but not human cells. Positron emission tomography (PET) is being increasingly used for diagnosis, staging, and follow-up of various malignancies. ET It has been studied in the evaluation of various tumors including but not limited to solitary pulmonary nodules, nonâsmall cell lung carcinoma, lymphoma, melanoma, breast cancer, and colorectal cancer (,1â,7). However, such techniques are only useful for detecting late stage infections, which usually have already become difficult to treat. Your doctor may order a bone scan if you have unexplained skeletal pain, a bone infection or a bone injury that can't be seen on a standard X-ray. /T1_2 1 Tf For any given CT examination, the protocol will vary according the individual requirement /T1_0 1 Tf The mission of the National Institute of Biomedical Imaging and Bioengineering (NIBIB) is to improve health by leading the development and accelerating the application of biomedical technologies. application/pdf endstream The Institute is committed to integrating the physical and engineering sciences with the life sciences to advance basic research and medical care.

In the last 15 years, slightly modified radiolabeled glucose molecules (F-18 labeled deoxyglucose or FDG) have been shown to be the best available tracer for detecting cancer and its metastatic spread in the body. 10 0 0 10 44 413.99985 Tm The PET technologist is a medical imaging technologist who has a high level of knowledge in positron emission tomography and is dedicated to producing high quality, diagnostically accurate results in a manner that is safe and effective for the patient. These carrier molecules vary greatly depending on the purpose of the scan. Only minute amounts of imaging substrate need to be injected (tracer principle) because of the high sensitivity of PET. Why PET scans are used. SPECT agents have recently become available for aiding in the diagnosis of Parkinson's disease in the brain, and distinguishing this malady from other anatomically-related movement disorders and dementias.
