What does CBV, CBF and MTT stand for?
CBV = cerebral blood volume; CBF = cerebral blood flow; MTT = mean transit time.
What is does pattern of perfusion indicate?
Large region of decreased CBV/CBF and increased MTT in the left MCA territory. The CBV and CBF deficits are matched meaning that there no ischaemic penumbra and this patient has had a large ischaemic infarct.
There is a large region of decreased CBV and CBF in the left parietal/posterior left frontal lobes consistent with infarct core. No significant CBV/CBF mismatch to suggest penumbra.
