Pet ct scan in hindi

Abstract This article was written to give health-care providers working in the field of nuclear medicine some background information on pediatric PET/CT. Specifically, it provides information regarding patient preparation and acquisition techniques necessary to obtain high-quality pediatric PET/CT images. It is targeted primarily at nuclear medicine technologists and CT technologists but may be beneficial to physicians performing PET/CT scans as well. The learning objectives for this article are to help the reader understand the practical aspects involved in pediatric PET/CT, to provide helpful tips and techniques that can be applied to pediatric nuclear medicine, and to help the reader understand and explore the various studies being done with 18F-FDG in children. • • • The use of 18F-FDG in PET/CT is well documented as a valuable tool in the staging and diagnosis of disease for many oncology patients. Although considered routine in adults, PET/CT in children has been somewhat limited. The recent acquisition of a Phillips Gemini GXL PET/CT scanner at The Hospital for Sick Children in Toronto, Ontario, Canada, has provided both clinicians and families with access to a service that previously required traveling great distances at personal expense. The purpose of this article is to familiarize technologists and clinicians with some of the practical aspects involved in successful pediatric PET/CT and explore some of the other PET/CT applications currently being used on childr...

What is a PET scan? 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. The patient will drink or be injected with the sugary tracer before the test. During the nuclear medicine scan, the patient rests on a table and slides into a large, tunnel-shaped scanner. The outpatient procedure is painless and varies in length, depending on the part of the body being evaluated. What is a PET/CT scan? This advanced nuclear imaging technique combines a PET scan and a computed tomography scan (CT) into one machine. A CT scan is similar to traditional X-rays. However, it takes pictures in thin slices from different angles. A computer is used to compile these thin slices and create a 3D picture of the X-rayed area. The combination of CT and PET imaging reveals information about both the structure (from the CT scan) and the function (from the PET scan) of cells and tissues in the body during a single session. Compared with an PET scan vs. CT scan Whereas CT scans take pictures from a variety of angles to show images of the patient's body organs, tissues and bones, the PET scan shows how the patient's cells react to a radiotracer, which may indicate cancerous areas. The combined PET/CT scan joins these two technologies together. What is ...
