Fig. 7B. 73-year-old man with claudication. On sagittal X-ray digital
subtraction angiography (A), right lateral plantar artery was diagnosed
as occluded (arrows) by all reviewers because it never fills, even on
delayed X-ray digital subtraction angiography images. However, on
time-resolved MR angiograms, lateral plantar artery is slowly filled by
gadolinium contrast and is patent (arrowheads). In this case, MR
angiography was considered more likely to be correct than X-ray digital
subtraction angiography.
