Neuroimaging methods. A, CTP maps and DWI lesions in a patient with a supratentorial lacunar infarct (upper row) and in a patient with a brain stem paramedian infarct (lower row). B, Representative examples of the quantification of NVT and TAR and the final DWI lesion in a patient with mismatch (left) and a patient with no mismatch (right). NVT indicates nonviable tissue; TAR, tissue at risk.

Rates of mismatch tissue according to different definitions of nonviable tissue and tissue at risk in patients with LI and nonlacunar infarcts. Values are mean and standard error of the mean. DT indicates delay time.
