What chemical is in the injection for pet scans?

F18-FDG: Different pet tracers exist for positron emitting scans (pet) scans. The most widely used for oncologic purpose is f18-fdg (fluorine-18-fludeoxyglucose) which is a modified glucose (fdg) attached to a radionuclide (f18) that emits gamma photons of 511 kev (energy) and has a physical half-life of 110 minutes. ...Read more

Pet Scan (Definition)

Pet scans most often use a radioactive form of glucose, the energy source for most of the cells in our bodies. The pet scanner can detect and measure how much of the radioactive glucose analog, f-18 fdg, is in a particular organ or region. The areas using more glucose are hyper metabolic and generally more worrisome. Our brains and sometimes hearts prefer glucose as food, making ...Read more

Getting my first pet scan, will i get sick or nauseous from the radioactive medication/injection that i will receive?

However, *if* you are also having a ct scan *with contrast* at the time of your pet scan, this may make you feel warm or unusual during injection, and can rarely result in allergic reactions.

Pet scan and 2 injections of thyroglobulin and i'm still breastfeeding how can I stop? My son is 19mns he doesn't need it just wants it

Weaning: It is always hard to wean a child if they are breastfeeding for comfort, but the best thing to do is explain to him in simple terms that he is a big boy now, and be consistent- do not say yes one day and no the next. Cold turkey. He will cry but he will get over it. Buy him a little present for being a big boy-. ...Read more

What is suv on a pet scan?

What is suv on a pet scan?

StandardUptakeValue: Suv simply stands for standard uptake value of a certain area on a scan (lesion, lymph node, etc). This is typically used to standardize pet scans between institutions and physicians. Studies show that maximum suvs of certain lesions are more indicative of cancer. This takes out some of the subjectiveness of reading the studies because by looking at this value, one can decide if it is high or low. ...Read more

What are the limitations of a pet scan?

What are the limitations of a pet scan?

Tricky: Not all cancers are hypermetabolic on pet scans and not all hypermetabolic activity in a pet scan is cancer. Inflammation/infection can also show hypermetabolic activity. Pet scans are performed in conjugation with ct (pet/ct) and though pet is great for detecting metabolism (high sensitivity), its specificity is not as great and also has poor anatomic resolution. Reading a pet requires care/skil. ...Read more
