also expose patients to ionizing radiation, CT has appropriately received the greatest scrutiny because of the relatively high radiation dose per exam – although it comprises about 15% of all medical imaging procedures, it produces approximately half of the population's medical radiation exposure [4...
Molecular characterization of endometrial tumors has resulted in a boom of investigative efforts aimed at ushering in a new era of tailored therapeutic regimens for patients with these malignancies. Although radiation and chemotherapy have been the cornerstone of treatment for patients with advanced or re...
Unlike X-rays and CT scans, MRIs don’t use damaging radiation. How MRIs Work The MRI is basically a tube-shaped magnet. While you're inside the machine, protons from water in your body get pulled into the magnetic field around you and start to line up. The machine also sends out ...

results take longer -- maybe 1 hour. MRIs are used to diagnose problems like torn ligaments, inflammation, or spinal issues. It's especially useful for looking at soft tissues (like organs and muscles) and the nervous system. UnlikeX-raysand CT scans, MRIs don’t use damaging radiation. ...
There are potential reasons for a discrepancy between CT and MR diagnosis. First, there may be a difference between measurements obtained within the vestibular aqueduct (CT) or intra-osseous endolymphatic sac/duct (MRI) at the mid- point (mid post isthmic) and opercular segments. Threshold ...
