Diagnosing acute lacunar infarction using CT perfusion

Highlights • CT perfusion (CTP) identifies large vessel ischemic stroke with high sensitivity. • We examined sensitivity for lacunar infarction (single perforating vessel occlusion). • CTP abnormalities were identified in 56% of lacunar stroke patients. • Mean transit time (MTT) was the most sensiti...

Description
Summary:Highlights • CT perfusion (CTP) identifies large vessel ischemic stroke with high sensitivity. • We examined sensitivity for lacunar infarction (single perforating vessel occlusion). • CTP abnormalities were identified in 56% of lacunar stroke patients. • Mean transit time (MTT) was the most sensitive map type. • Recognition of CTP abnormalities in lacunar stroke may improve diagnostic confidence.
