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...

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....
