Wide-array CT reduces dose, improves images of thoracic aorta
By Eric Barnes
Wide-detector-array CT holds a number of advantages for scanning the thoracic aorta, including wider anatomic coverage of the heart and aorta, less contrast use compared to traditional scanners, and lower radiation dose, according to two studies from the Cleveland Clinic Foundation.
