Few trauma patients who develop potentially deadly blood clots in the lungs (pulmonary embolism) also have clots in the deep veins of their pelvis and legs (deep venous thrombosis), challenging commonly held beliefs about the association between the two conditions, according to a report in the October issue of Archives of Surgery, one of the JAMA/Archives journals. "For decades, it has been taught that pulmonary embolism is a sequel of deep venous thrombosis," the authors write as background...

Radiologists have discovered that prospective electrocardiogram (ECG) gating allows them to significantly reduce the patient radiation dose delivered during computed tomography (CT) angiography, a common noninvasive technique used to evaluate vascular disease, according to a study published in the October issue of the American Journal of Roentgenology (AJR). The study, performed at the Medical College of Wisconsin, compared the use of retrospective ECG gating (when the radiation beam is on...

While screening for possible pulmonary emboli using pulmonary CT angiography, a new study shows that radiologists can effectively lower the patient radiation dose by approximately 44% and improve vascular enhancement without deterioration of image quality, according to a study performed at Brigham and Women's Hospital and Harvard Medical School, Boston, MA.A total of 400 patients believed to have a pulmonary embolism were evaluated using pulmonary CT angiography. Two hundred patients were...

MDCT angiography leads to accurate recommendations for successful treatment of patients with critical limb ischemia, sometimes allowing the patients to avoid more complicated surgery, according to a study performed at the Medical University of Vienna, Vienna, Austria.The study included 28 patients with severely blocked peripheral arteries. MDCT angiography indicated that nine patients should undergo non-surgical endovascular treatment such as percutaneous angioplasties or stent placement....

ST. LOUIS "“ Electron-beam computed tomography (EBCT) is more accurate than conventional catheter angiography for detecting a dangerous congenital heart abnormality that could cause sudden death, according to research by a Saint Louis University radiologist published last month in Catheterization and Cardiovascular Interventions: Journal of the Society for Cardiovascular Angiography and Interventions. Esat Memisoglu, M.D., assistant professor of radiology at Saint Louis University...

Computed tomography of the coronary arteries (CT angiography of the heart) is a very new technique and, if done carefully, allows excellent visualization of the vessels that supply blood to the heart ("New scan technology lets doctors see heart," Nov. 17). We've now done 50 of these studies at Seattle Radiologists and there are several factors we believe the public should know. It's important that this study should be done only after consultation with one's personal physician or cardiologist....
