Noncontrast, flow-dependent FIESTA offers a safe and effective alternative to gadolinium-enhanced MR angiography for renal artery evaluations, according to a study from Japan presented on Thursday.
More »Medicare's decision against a national coverage determination for coronary CT angiography is not the end of conflict for the modality. It is just the beginning. The next battle involves fulfilling the promises the multisociety alliance made to assure the Centers for Medicare and Medicaid Services...

More »Coronary CT angiography has been found to be a powerful tool to evaluate patients suspected of coronary artery disease who are at low to intermediate risk. The task now for many researchers is to further refine specific patient populations for whom coronary CTA can be beneficial. One such patient...
More »In the October 2006 issue of Diagnostic Imaging, I wrote a brief article describing the benefits of using prospective gating when performing coronary CT angiography.
More »Coronary CT angiography is commonly performed using beta blockers to slow the heart rate and reduce motion artifacts in the images, thereby improving diagnostic accuracy. Oral metoprolol is often prescribed one hour prior to the procedure. Intravenous metoprolol may be given immediately prior to the...
More »Coronary CT angiography is one of the most promising new applications of CT technology. Despite the increasing number of detectors in CT scanners, however, coronary CT imaging had not solved the key issue: dealing with a structure that is in almost constant motion. That is, until the advent of dual...
More »During my first eight years of performing and interpreting cardiac multislice CT, up to 2006, our mantra was always that slower heart rates improve diagnostic image quality. Aside from image quality, slow heart rates also traditionally translated into lower patient radiation exposure. Our most...
More »A noninvasive technique to detect vulnerable atherosclerotic plaque is critically needed. Formation of atherosclerotic plaque is a dynamic inflammatory process that involves interactions between atherogenic lipoproteins and macrophages. As vulnerable plaques are usually numerous, extending beyond...
More »Questions remain from practitioners, payers, and administrators regarding the economic impact of coronary CT angiography on established diagnostic modalities and the effects on reimbursement within imaging. To address these concerns, we have developed the CCTA Data Registry, which now consists of...
