CAD fails to make up for inexperience in reading VC studies September 30, 2009 -- Using computer-aided detection (CAD) software with a 3D display technique can increase sensitivity for inexperienced readers of virtual colonoscopy exams, but it fails to narrow the performance gap with experienced interpreters, according to a study published in the October issue of Clinical Radiology.
VC excels at diverticulosis staging September 28, 2009 -- Although virtual colonoscopy practice has always focused on adenoma detection and colon cancer prevention, the exam is proving to be formidable in the staging of diverticular disease, a scourge of fast-food Western nations that affects most of their citizens by age 60.
CT, MRI look at different etiologies for myocardial fat September 25, 2009 -- New studies appearing in Radiology online examine two different etiologies associated with myocardial fat deposits. Their presence on imaging studies, both in CT and MRI, can help radiologists evaluate the extent of disease and potential risks.
Cardiac MR changes management in 62% of cases, study shows September 25, 2009 -- A German study has found that cardiovascular MR changes clinical management in approximately two-thirds of heart patient cases and can also eliminate the need for additional imaging procedures. Researchers also concluded that cardiovascular MR with contrast is safe and produces diagnostic-quality images in 98% of cases.
