Ct Fistulogram Or Sinogram
Computed tomography is also known as CT scan. Ct uses xrays taken an 360 degrees combined with a computer to see"inside" the body. The table moves as the xray tube and detectors spin around the patient 10 times a second or more! the image shows excellent soft tissue detail, enhanced with injection of intravenous contrast or oral contrast. This way the body is shown in slices, in any plane, usually axially, but ...Read more
Sometimes...: It depends on the nature of the abnormality and no urgent the reading radiologist thinks the problem is. There are many varieties of abnormal, and many just need a routine follow up, sometimes another study in 6 months or so...So unless the radiologist thinks it is an emergency, the ordering doctor may not my informed right away. ...Read moreSee 2 more doctor answers
CT/PET: CT uses X-rays to produce images. The radiation passes through the body into detectors. With PET, a radioactive labelled substance, usually glucose, is injected into the body. Glucose is metabolically active, so PET forms functional images based on areas of high metabolic activity. CT images anatomic structure. Sometimes the 2 are combined, called PET/CT fusion imaging. ...Read moreSee 2 more doctor answers
None or a lot: The question is less about how many are safe and more about the question you're trying to answer. If you've been in a major car accident and are bleeding to death, 10 cts are very safe. If you are just curious to see your insides, none are safe. It is a decision of the risk of the scan versus the benefit of the information gained. It should be discussed with your md ordering the exam. ...Read moreSee 1 more doctor answer
Depends: The cancer risk from each CT is very minor (a fraction of one percent), especially when compared to the lifetime risk of developing a cancer from any cause (approximately 40 percent). As for getting multiple CTs, it's really a risk benefit analysis, and it really depends on what you are getting the CT for. I think it's appropriate to speak with your doctor about this issue. ...Read moreSee 1 more doctor answer
Hard to say: There is no simple answer. It depends on other sources of radiation accumulated during your lifetime as well as the reason for the scans themselves.

On a pet/ct preliminary report came out on 11/22 they said final report will follow. Generally is there much difference in info on prelim vs final?
Depends...: Ultimately it depends on the type of preliminary and who read it. However, in my experience, there are frequently minor findings that will be added and or different from the prelim report and there are only occasionally significant discrepancies between the two reports. I hope this helps answer your question. ...Read moreSee 2 more doctor answers
It combines: the high sensitivity of PET with the high level of anatomic detail of CT, so an abnormality on PET can be accurately localized. ...Read more
Caution: A ct abdomen equals about 500 chest xrays, add a pelvis, another 500. This is 5 years background radiation and exposure is cumulative. Worse when young! think twice about the real need before doing xrays.
