How Does Metal Affect The Results Of A Pet Scan
Usually not much: Metal can block the gamma rays that are emitted by the patient, and block the xrays from the ct portion of the pet/ct, which can create errors on one portion of the exam (called the attenuation corrected scan). However, the original pet data from the scan (uncorrected) is always available for review, so if the standard images have artifact on them, the uncorrected images can be reviewed. ...Read moreSee 2 more doctor answers
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

Radioactive drugs (usually a glucose analog) distribute based on differences in function, release a positron (antimatter), which is destroyed by combining with an electron, making an x-ray we detect. Follow the directions the imaging center gives exactly, because patient prep is critical to getting the best test. Pet/cts are usually read the same day. ...Read moreSee 2 more doctor answers

Oncology: How long after a Whipple operation can a patient still have a slightly annoying pain as a result of inflammation as seen on a PET scan?
Weeks: Since the Whipple requires several anastomosis, there is the potential for slight and temporary leaks. These areas should be drained at the time of surgery and include suturing the common duct to small bowel, and implanting the transected body of pancreas into jejunum. These sites are well known to cause, even with good drainage, temporary leakage setting up inflammation seen on scan. ...Read more
