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
Discuss with doctor.: It is best to discuss your pet scan results with your physician so that you can be sure that you have a detailed and correct understanding of the scenario. If you have any specific questions, be sure to have them clarified. Without the results, it is difficult to answer your question. Hope this helps. ...Read more
How do pet scans work? My wife is scheduled for a pet scan and i was wondering how it works. Is this a good test relative to the other kinds of tests you can do? Is it accurate? Do you know how long it usually takes to get the results back?
Positrons -Really!!: A pet/ct looks at the function of the body. 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

What can a Heart PET Scan diagnos ?
If it is Abnormal result, what is the outcome needed procedure or treatment plan ?
Heart perfusion: A heart PET scan evaluates the blood flow to the heart. It can also detect prior damage and give information on the overall function of the heart. This test is not widely used in cardiac evaluations, thus addressing an abnormality on the scan would depend on why your doctor recommended the scan for you. ...Read moreSee 2 more doctor answers
Post op seminoma, in r testicle. Pet scan done for suspecious nodes. Pet scan result shows negative for any abnormalility. This means no seminoma?
Surveillance: A negative pet scan means there is no accumulation of cancer cells large enough to be discernible by the pet scanner. There is a resolution limit of about 7mm in size to be seen, some are better now. I am not trying to scare you, but your doctor i'm sure will continue to caution you and continue surveillance for a period of time safe to say you are cancer-free. ...Read moreSee 1 more doctor answer
What could cause a reduced glucose metabolism in a PET scan?that was my result.It was done bcause I have 30 inactive cns lesions and anxiety for years

Hi, if pet scan results for pancreatic cancer are negative after treatment is this mean that the patient was recovered completely ?
No: The medical definition of a cure is usually no cancer present for 5 years after the end of treatment. PET scans can miss small tumors and can also give a falsely negative results for other reasons. That being said, it is a positive sign, better chance of a cure than if cancer were still present, obviously. ...Read more

Yes: There are differences in techniques between the ct scan with a pet scan and a general ct scan. Additionally, radiologists may measure a nodule slightly differently.

My ct-cat-pet scans reveal unclear results, acc to my drs. After my sigmoid colon was removed 'coz of a tumor. Yet I am taking xeloda500m. Justified?
back in may i had a nuclear stress test results could not determine if the image was a breast artifact or something else and a PET scan was warranted .. in other testing he had done the same day ischemia was found .. when went for follow-up he said i did
SPECT vs. PET: On regular myocardial perfusion SPECT imaging, large breasts and large body habitus can cause attenuation artifacts. This is often avoided on cardiac PET where attenuation correction is used. If the breast shifts between stress and rest SPECT imaging, false positive for ischemia could occur. ...Read moreSee 1 more doctor answer
