How Accurate Are Ct Scans For Detecting Ovarian Dermoid Tumors
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

They can: The diagnostic yield of increased with use of IV contrast material as some tumors disrupt the so called blood brain barrier affording the contrast the ability to infiltrate from the blood stream into the tumor. Small tumors that have not disrupted the integrity of blood vessels may escape detection on CT especially if the have the same radiographic tissue density as their surrounding tissue. ...Read more
Not always: Brain CT scans without contrast do not always miss cerebellar tumors. A tumor whose density is different from that of its adjacent brain tissue, or whose size is such that it pushes away adjacent brain tissue (distorting the normal shapes and outlines) will likely be visible even on noncontrast scans. ...Read moreSee 1 more doctor answer
I was diagnosed with carcinoid syndrome in march of 2007. I have had yearly CT scans since then, and no tumor has been found. Is this common?
Not uncommon: Carcinoid is a type of tumor that usually arises within the gut wall. Though larger tumors can often be seen on ct scans, it is not unusual for a small carcinoid to be difficult to see on ct (especially if it arises in the small bowel). If the carcinoid is aggressive or spreads, ct is likely to see it. A radionuclide test (e.g. Octreoscan) is a useful adjunct when ct does not detect the tumor. ...Read more
Read more about it: To learn more about imaging and radiation, see: http://www.Conciergeradiologist.Com/ct-scan-radiation.Html and http://www.Conciergeradiologist.Com/radiation-exposure.Html. Properly indicated imaging studies represent, by definition, situations where the risks of radiation are outweighed by the benefits to the patient. I wouldn't worry about ct scan radiation causing a brain tumor. ...Read moreSee 1 more doctor answer
