Previous studies suggest that for patients with a suspected blood clot in a deep vein of a leg, withholding anticoagulation therapy after a negative whole-leg compression ultrasound is associated with a low risk of developing a blood clot during the subsequent three months, suggesting that multiple ultrasounds may not be necessary for low-risk patients, according to a report in the Feb. 3 issue of the Journal of the American Medical Association.
Research published in the December issue of the Journal of Nuclear Medicine suggests that SPECT, when combined with low-dose CT, can provide an accurate diagnosis for pulmonary embolism.
Lung scintigraphy is more reliable than CT pulmonary angiography (CTPA) in identifying or excluding pulmonary embolism in pregnant patients, according to a study in the November issue of the American Journal of Roentgenology.
CT angiography (CTA) can identify abnormalities and injury beyond the pulmonary arteries, including broken bones and heart disease in pediatric patients, according to a study published in the September issue of the American Journal of Roentgenology.
Since the Appropriateness Criteria for cardiac CT (CCT) was published in 2006, the modality has experienced rapid growth in technology and clinical use. When the American College of Cardiology (ACC) formally reviews the criteria next year, there might be room to add more indications to the "appropriate" category, including the "triple rule-out" exam, according to a study presented at the Society of Cardiovascular Computed Tomography (SCCT) meeting in Orlando, Fla., last week.
The FDA has granted 510(k) clearance of the NeuViz 16 multi-slice CT system to Neuisys Imaging System Solutions.
Acting Surgeon General Steven K. Galson, MD, has issued a ‘call to action’ to prevent deep vein thrombosis (DVT) and pulmonary embolism (PE).

For the treatment of acute venous thromboembolism (VTE), a fixed dose of the new anticoagulant dabigatran (Pradaxa; Boehringer Ingelheim) is as effective as warfarin, has a safety profile that is similar to that of warfarin and does not require laboratory monitoring, based on the findings of the RE-COVER trial published online Dec. 6 in the New England Journal of Medicine.
The use of catheter-directed thrombolysis saves lives and should be considered a first-line treatment option for massive pulmonary embolism, according to a study in the November issue of the Journal of Vascular and Interventional Radiology.
Each year, nearly three million people are diagnosed with deep vein thrombosis. Of those, 600,000 are diagnosed with a pulmonary embolism (PE) caused by a venous clot. Of those, 200,000 will die from PE. Cook Medical has streamlined its inferior vena cava (IVC) filter delivery system, NavAlign, to help interventionalist place filters that help patients avoid PE.
An evaluation of coronary artery disease (CAD) on an Apple iPhone has high sensitivity and negative predictive value among evaluable arteries, according to a proof-of-concept study presented at last week's Society of Cardiovascular Computed Tomography (SCCT) meeting in Orlando, Fla.
Rosuvastatin (Crestor from AstraZeneca) significantly reduced the occurrence of symptomatic venous thromboembolism (VTE) in the atria of apparently healthy persons, according to a sub-study of the JUPITER trial published in the April 30 issue of the New England Journal of Medicine.
Three studies have found that the “triple rule-out” exam is advantageous in certain patient populations and the senior author told Cardiovascular Business News that the postprocessing involved is simple and straightforward.
In patients with suspected acute coronary syndrome presenting to the emergency department for the primary purpose of evaluation of the coronary arteries, a dedicated coronary CT protocol provides excellent quality images of the coronary arteries and proximal ascending aorta, but images of the pulmonary vasculature are insufficient for the exclusion of pulmonary embolism (PE).
