Primary Outcome Measures:
  • Radiographic Densities at Selected Regions in Contrast-enhanced CT Examination by Location (Abdominal Aorta), kVp 80 and Contrast Type (Ioforminol vs Iopamidol), Concentration (Ioforminol 160 or 200) and Dose Levels (1.0, 1.5, and 2.0mL/kg). [ Time Frame: Within 5 minutes after administration for either Ioforminol or Iopamidol. ]
    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.

  • Radiographic Densities at Selected Regions in Contrast-enhanced CT Examination by Location (Abdominal Aorta), kVp 100 and Contrast Type (Ioforminol vs Iopamidol), Concentration (Ioforminol 160 or 200) and Dose Levels (1.0, 1.5, and 2.0mL/kg). [ Time Frame: Within 5 minutes after administration for either Ioforminol or Iopamidol. ]
    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.


Secondary Outcome Measures:
  • Evaluate the Overall Safety of Ioforminol and Iopamidol Injections by Recording Treatment Emergent Adverse Events (TEAE). [ Time Frame: Up to 72 hours for safety monitoring post Ioforminol and Iopamidol administration. ]
    Recording the occurrence of treatment emergent adverse events (TEAE).
