On the other hand, lab markers such as D-dimer results showed only weak correlations.April 3, 2011CTAuntMinnie.com CT InsiderMarch 30, 2011CTCT of testicular cancer associated with new malignanciesRepeated CT scans of testicular cancer patients are associated with an increased number of secondary cancers among older men, concludes a new study from the University of California, Davis.March 30, 2011CTStudy finds CTC screening's benefits outweigh radiation risksThe benefits of colon cancer screening with virtual colonoscopy far outweigh the risk of radiation-induced cancers, even when the exam is repeated every five years between the ages of 50 and 80, concludes a new study in the April issue of the American Journal of Roentgenology.March 29, 2011InterventionalSIR: Radiation protection supplement protects DNAA new antioxidant formula earned high marks in a small study for protecting against DNA damage from radiation exposure, according to a presentation at this week's Society of Interventional Radiology (SIR) annual meeting in Chicago.March 28, 2011CTStudy finds no significant risk from airport x-ray scannersThere is no significant radiation threat to air travelers from airport scanners, researchers reported March 28 in the Archives of Internal Medicine. In fact, the radiation received in a typical airport full-body scan is equivalent to the background radiation of about nine minutes of flying time, the authors stated.March 27, 2011CTAscending colon rotation can mask colonic polypsPolyps in the ascending colon can mimic mobile contents such as fecal matter when patients turn from prone to supine position at virtual colonoscopy, potentially skewing interpretation, a new study indicates. Simple awareness of the phenomenon can go a long way toward helping radiologists avoid misinterpretation of virtual colonoscopy results.March 24, 2011Previous PagePage 105 of 258Next PageTop StoriesMolecular ImagingPET links brain receptor to emotional numbing in PTSDTo date, only a single study has investigated CB1R availability in humans exposed to trauma.Womens ImagingCEM, DBT show promise for preoperative breast cancer stagingMRIMRI illumines how the brain maintains 'representation' of phantom limbsDigital X-Ray3D DEXA reveals lower bone density in diabetes patientsMRIGadolinium in ... beer?
