Figure 2c:

Mean qualitative (image quality) and semiquantitative (stenosis degree) scores for nonenhanced FSD MR angiography, as compared with contrast-enhanced time-resolved (TR-MRA) or high-spatial-resolution (HR-MRA) MR angiography, with corresponding schematics of hand arteries. Lower mean image quality scores correlate with improved image quality. Higher mean stenosis degree scores correlate with increased apparent degree of stenosis. Mean image quality scores for the (a) control subjects and (b) patients and mean stenosis degree scores for the (c) control subjects and (d) patients are compared between the angiographic techniques. In each set of numbers, first value is mean score with FSD, second number is mean score with time-resolved or high-spatial-resolution MR angiography, and number in parentheses is P value for given comparison.
