• Two common types of acute injury are recognized: – Cerebral infarction (stroke) is a regional ischemic lesion usually due to local vascular occlusion (thrombotic or embolic) – Ischemic (hypoxic) encephalopathy is a diffuse lesion characterized by selective loss of neurons due to global ischemia, usually as a result of hypotension

Diagnostic Role in Acute MI • Relationship of WMA to pathologic infarct size – A/dyskinesis • Can over-estimate infarct size – Adjacent to scar – Hypokinesis • Nonspecific • Overestimates infarct size – Stunning, tethering, ischemia – Lack of systolic thickening (wall thinning) • Best estimator of infarct size

The infarct growth region (IGR) was defined by subtracting the acute DWI lesion volume from the INF region volume. The hypoperfused salvage region (HS) was defined by subtraction of the INF region volume from the acute MTT 4 seconds abnormality (Figure 1).
