Trial Outcomes & Findings for Open Label, Randomized Study of Low Concentration Ioforminol Injections for Use in Abdominal CECT in Healthy Volunteers (NCT NCT01672996)

NCT ID: NCT01672996

Last Updated: 2014-05-29

Results Overview

Quantitative measurement of the radiographic density (as measured by Hounsfield Units (HU) ) at the abdominal aorta at the level of the celiac artery. The greater the contrast attenuation, the higher the HU.

Recruitment status

PRIMARY outcome

Timeframe: Within 5 minutes after administration for either Ioforminol or Iopamidol.

Population: Evaluted 33 subjects using 80 kilovolt peak (kVp), a measure of the maximum electrical potential in kilovolts across an x-ray.

Quantitative measurement of the radiographic density (as measured by Hounsfield Units (HU) ) at the abdominal aorta at the level of the celiac artery. The greater the contrast attenuation, the higher the HU.
