PRIMARY outcome

Timeframe: Within 10 minutes post contrast administration.

Population: 249 subjects completed assessments, for overall discomfort, heat or pain between Iodixanol and Iopamidol during the diagnostic phase of imaging.124 subjects received Iodixanol and 125 subjects received Iopamidol.

The number of subjects experiencing overall discomfort, heat or pain between Iodixanol and Iopamidol during the diagnostic phase of imaging.

SECONDARY outcome

Timeframe: Within 10 minutes post contrast administration.

Population: A recruitment error occurred with a subject in each treatment group. Therefore, the subject's efficacy data were excluded from this efficacy analysis. This resulted in a total of 126 Iodixanol subjects and a total 125 Iopamidol subjects were used in the imaging analysis.

Overall Image Quality rated as 'Excellent, Adequate or Poor' by radiologists blinded to the contrast administration.
