Latest Computed tomography angiography Stories
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.
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.
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
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.
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.
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).
