CT-CBF Maps Optimally Correlate with Admission DWI in Acute Stroke but Thresholds Vary by Post-Processing Platform

摘要

PurposeAdmission infarct core lesion size is an important determinant of management and outcome in acute (<9 hrs) stroke. Our purpose was to: (1) determine the optimal CT perfusion (CTP) parameter to define infarct core using various post-processing platforms, and (2) establish the degree of variability in threshold values between these different platforms.
