FIG 1. MRA and perfusion MR imaging during the headache phase.
A, MRA shows dilatation of the middle and posterior cerebral artery branches on the right side (arrows) compared with that on the left side.
B and C, Relative cerebral blood volume (rCBV) map (B), with time-concentration curves (C) based on perfusion MR imaging findings, shows hyperperfusion of the right hemisphere (arrows in B) compared with that of the left hemisphere.

FIG 2. Repeat MRA and perfusion MR imaging 1 month after the attack.
A, MRA shows a symmetric appearance of the middle and posterior cerebral artery branches.
B and C, rCBV map (B) with time-concentration curves (C) also shows symmetric perfusion of both cerebral hemispheres.
