The Bookend method has been presented with water exchange effects correctionfor quantitative cerebral blood flow (qCBF) measurement. Acute strokepatients were scanned with the Bookend protocol, and qCBF maps wereobtained. The diagnostic accuracy for ischemic threshold was determinedusing an ROC analysis, and the ischemic threshold values were estimated in white matter and gray matter, respectively.
