MDCT angiography for detection of pulmonary emboli: Comparison between equi-iodine doses of iomeprol 400Â mgI/mL and iodixanol 320Â mgI/mL

The greater iodine delivery rate achievable with iomeprol 400 compared to iodixanol-320 at equi-iodine dose and injection rate permits consistently greater attenuation at all levels of the pulmonary arterial tree.
