Freyhardt P, et al. - A comparative evaluation was undertaken of the high-pitch dual-source computed tomography angiography (CTA) of the aorta acquired with different tube currents and methods of image reconstruction in patients with Marfan Disease (MFS). It was reported that low-kV computed tomography (CT) protocols with IR permitted for CTA of the entire aorta in excellent image quality and diagnostic confidence with a dose reduction of up to 80% than 120 kV in MFS patients. Data suggested 100 kV for baseline CT and 80 kV for follow-up CT scans as tube voltage.
