MRI: MedlinePlus Medical Encyclopedia
It is often used when traditional angiography cannot be done.Normal values A normal result means the body area being studied looks normal.What Abnormal Results Mean Results depend on the part of the body being examined and the nature of the problem. The dye helps the radiologist see certain areas more clearly.Small devices, called coils, may be placed around the head, arm, or leg, or other areas to be studied
CAT Scan (CT) - Sinuses
top of page What are some common uses of the procedure? View larger with caption CT of the sinuses primarily is used to: detect the presence of inflammatory diseases. However, both the American College of Radiology (ACR) and the European Society of Urogenital Radiology note that the available data suggest that it is safe to continue breastfeeding after receiving intravenous contrast
Typically the contrast is contained in a special injector, which injects the contrast through a small needle taped in place (usually on the back of the hand) during a specific period in the CT exam.Once the contrast is injected into the bloodstream, it circulates throughout the body. In some cases, CT can still provide valuable diagnostic information without the administration of a contrast agent, so the physician may decide this is the best course of action
In addition, the movement of the table through the scanner creates a spiral path for the x-ray beam, which allows the computer to create two-dimensional cross-section scans. Traditional X-RaysA CT scan is different from a traditional x-ray in that during a CT scan numerous x-ray beams are sent into the body, while electronic x-ray detectors rotate around the body, measuring the amount of radiation the body absorbs
What Is The Difference Between A CT Scan And An MRI Scan? - Naked Science Forum
However, the development of multi-detector CT scanners with near-isotropic resolution, allows the CT scanner to produce data that can be retrospectively reconstructed in any plane with minimal loss of image quality.For purposes of tumor detection and identification, MRI is generally superior. MRI, on the other hand, uses non-ionizing radio frequency (RF) signals to acquire its images and is best suited for non-calcified tissue.CT may be enhanced by use of contrast agents containing elements of a higher atomic number than the surrounding flesh (iodine, barium)
I am glad I have helped you :)A CT scah of the abdomen does not show the stomach that well...if there is a concern regarding the lining of the stomach (ulcer, for example) a scope of the stomach is really what you need.The diaphragm is usually visualized on the CT scan as is the base of the lungs.The intestines are also visualized but a CT scan is not the test of choice for certain intestinal problems.

posted @ Monday, November 08, 2010 11:11 PM by Ari M I had a MRCP(MRI WITH CONTRAST OF LIQUID AND IV)and felt horrible pain in hand when it went through iv,worst pain ever.It was sore for a few days but then I woke up today and hand swelled double and pain in hand and up to my elbow..does anyone know why???..but I would still have again if it figures out whats wrong posted @ Monday, December 13, 2010 4:34 PM by tammie from kentucky I had a CT today with the contrast through iv.. I truly think it depends on the tech, I've had the stabby ones who just aim and throw, and then I get these guys like today, who actually take their time and take the patient into consideration
