Research studies published in November and December demonstrate there are no one-stop radiologic shops for the diagnosis of cardiovascular disease. Each modality is endowed with specific strengths that recommend it as the instrument of choice in specific clinical situations.
More »Published clinical studies are expanding the diagnostic limits of multislice CT and other modalities for cardiovascular applications. A meta-analysis in the November Radiology offers a powerful argument in favor of its use for diagnosing lower extremity disease. Other, more preliminary, studies...
More »Peer-reviewed research published in October offered an eye-opener for anyone who thinks that cardiac imaging is all about measuring coronary artery occlusions. Variety spiced the most notable imaging research of the month. Studies produced fresh insight into the relevance of renal artery calcium,...
More »The heart may hold secrets to predicting the future onset of Type 2 diabetes, with the help of proton MR spectroscopy. This elegant finding emerged from research by Lidia Szczepaniak, Ph.D., and colleagues at the University of Texas Southwestern in Dallas. Using anatomical MRI and metabolic MRS,...
More »The first substantive clinical trials of dual-source CT suggest it will deliver on a promise to improve the detection of coronary artery disease. A Dutch study published in the August 21 issue of the
Journal of the American College of Cardiology found it is 95% sensitive and 95% specific on a...
More »Despite heated interest in cardiac CT, echocardiography continues to anchor the diagnosis and evaluation of coronary artery disease for most clinical practices. Echo possesses prognostic as well as diagnostic power, as demonstrated in a large Weill Cornell Medical College study. It found strong...

Journal of Nuclear Medicine suggests that radiolabeled recombinant tissue plasminogen activator can perform double duty for evaluations of deep vein thrombosis: It can diagnose the presence of DVT and distinguish between new and old thrombi....
More »A review of the current literature reveals a difference of opinion regarding whether to screen diabetic patients with CT and an inherent flaw with hybrid SPECT/CT scanners resulting in misregistered images. Researchers also optimized a contrast protocol for the triple rule-out procedure and advise...
More »Recently published studies reflect the versatility of cardiac MR, multislice CT, rubidium-82 PET/CT, and stress echocardiography for shedding diagnostic light on various aspects of coronary artery disease and other cardiac conditions.
More »March was a month of notable progress for cardiac MR, with studies demonstrating the impressive prognostic power of adenosine stress perfusion and dobutamine stress wall motion imaging. The combination was nearly perfect in identifying patients who would be safe from cardiac death or myocardial...
