Legend
MRA demonstrates abrupt termination of the left MCA. DWI shows
increased signal in the left MCA distribution and there is corresponding
decreased ADC values.
Legend
Hemodynamic time-signal intensity curves show no T2* signal intensity
drop on the left relative to the right. There is decreased CBV (left images),
CBF (upper right), and increased MTT (lower right).
Legend
Hemodynamic time-signal intensity curve shows no T2* signal intensity
drop on the left relative to the right. The time to minimum is prolonged
(green & blue areas) on the left on all images. The orange/red areas are
artifactual (overshoot) due to zero flow to those areas.
