Randomized Controlled Trial
Reducing contrast medium volume and tube voltage in CT angiography of the pulmonary artery.
To evaluate image quality after contrast medium (CM) and tube voltage reduction in computed tomography angiography (CTA) of the pulmonary artery. ⋯ Low tube voltage (80 kV) CTA using 50 ml CM is not inferior to CTA at 120 kV using 100 ml CM.
