Signal intensities in four cerebral arterial territories (anterior cerebral artery, middle cerebral artery, posterior cerebral artery, and whole area) were measured using both 4D-MRA and SP-ASL, and peak time of maximum intensity through each technique was recorded. Regression analysis was used to determine the correlation between the peak times using 4D-MRA and those using SP-ASL, and the regression function obtained was used to estimate the peak time for SP-ASL (optimum post-label delay) from that obtained for 4D-MRA.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      The peak time in anterior cerebral artery territory for SP-ASL was expressed as 1.19\u2009+\u20090.30\u2009\u00d7\u2009(peak time of 4D-MRA) s, ( p\u2009=\u20090.017, r\n                      <jats:sup>2<\/jats:sup>\n                      \u2009=\u20090.14).
