CT venography increases detection of dangerous blood clots
Recurring blood clots in the lungs can be prevented with computed tomography (CT) of the legs, according to a study published in the February issue of the journal Radiology. The researchers found that indirect CT venography (CTV) can identify the formation of blood clots in the legs that have the potential to break free travel to the lungs and block an artery - a potentially fatal disease called pulmonary embolism.Disease. CT lung (CTPA), a type of lung scan is often used to detect the presence of blood clots in the lungs. But because many clots in smaller arteries are not visible on the lung scan, thromboembolic disease in some patients can not be diagnosed. Indirect CTV can help a problem of blood clotting. Studies have shown that not enough deep vein thrombosis treated
with recurrent pulmonary embolism, said lead author Matthew D. Cham, MDRochester, New York. In a large study, Dr. Cham and his colleague David F. Yankelevitz, Claudia I. Henschke and MD, Ph.D., MD, New York Presbyterian Hospital-Weill Medical College of Cornell University in New York, found that the performance of the CTV with CTPA, the detection rate of thromboembolic disease increased by 20 percent . Each year over 600,000 people in the United States suffer from pulmonary embolism, and kills more than 60,000 of them, according to the National Heart, Lung and Blood Institute.
free and travels to the lungs. The researchers studied 1,590 patients undergoing both CTPA and CTV the other to New York Presbyterian Hospital-Weill Medical College of Cornell University
zwischen suspected pulmonary embolism 1998 and 2001. CTPA detected pulmonary embolism in 15 percent or 243 patients. CTV detected deep vein thrombosis in 148 or 9 percent of patients. Of the 148 patients only 100 were diagnosed with pulmonary embolism by CTPA state.. Perform In both the CTV and CTPA, addressed a series of X-rays through the body from different angles, thereby cross-section of the body by computer in
