Fluoroseopy Fluoroscopy is a studdy of moving body strctures. It is an imaging technique that uses X-rays pass the body part to he esamined to obtain real time moving images of the internal structures of a patie the use of a fluoroscope. In its simplest form, a fluoroscope eonsists of an X-ray source and fluoew between which a patient is placed. It is most commonly used to view the upper Gl tract (stomach, cduodenum, the lower GI tract. Modern huoroscopes...

Radioisotopes are often used in diagnostic imaging for detecting disease. The isotope 18F, which has a half-life of 110 min, is used in medical imaging. What percentage of the original activity in the sample remains after 600 min? Show your work, include units, and pay attention to significant figures. Remember that half-life is given by: k=(0.693)/t1/2.

Fluorodeoxyglucose (FDG), incorporating the positron emitter fluorine-18, is a commonly used radioisotope in PET scans. Which of the following statements about PET scans is correct? Select one: a. FDG is an analogue of glucose, so areas of low activity in a PET scan indicate areas of high glucose metabolism b. FDG in solution is injected into vascular system, so areas of high activity in a PET scan indicate areas of high vascularization c. FDG is metabolized by tumour cells more...
