[Usefulness of CT-perfusion in acute cerebral infarction].
CT-perfusion (CTP) examination was performed in 30 cases of acute cerebral infarction (ACI) caused by middle cerebral artery (MCA) occlusion. Data were analyzed using cerebral blood flow (CBF), cerebral blood volume (CBV), and mean transit time (MTT). The results of the affected side were compared with those of the other side in terms of relative value and difference. A high correlation in relative value was found between CBF and CBV (r=0.81) and in both the relative (r=0.76) and difference (r=0.77) value between CBF and MTT. No correlation was seen between CBV and MTT. The time-density curve, along with CBF, CBV, and MTT, was classified into three patterns of ischemic brain damage: collateral, delayed, and flat patterns. In conclusion, CT-perfusion examination is useful for determining a treatment plan in ACI.
