(a, b) Coronal subtraction MIP VFA MR angiograms (repetition time, two R-R intervals; echo time, 10 msec; variable flip angle) demonstrate vessel irregularity and poor visualization of the proper digital arteries (a) at cold imaging and (b) after rewarming, with no appreciable change in vessel caliber and no increase in the number of visualized vessel segments after rewarming.
