<P>PROBLEM TO BE SOLVED: To provide a method for quantitating cerebral blood flow at rest and during drug loading with low invasiveness and high accuracy. <P>SOLUTION: Cerebral blood flow during drug loading is determined from a following formula (1). (t<SB POS="POST">3</SB>: dosage time in drug loading, t<SB POS="POST">5</SB>: imaging start time in drug loading, t<SB POS="POST">6</SB>: imaging end time in drug loading, mC<SB POS="POST">f</SB>:constant, k<SB POS="POST">1</SB>: cerebral blood flow at rest, k<SB POS="POST">2</SB>: brain tissue blood flow rate constant at rest, k<SB POS="POST">1d</SB>: cerebral blood flow during drug loading, k<SB POS="POST">2d</SB>: brain tissue blood flow rate constant during drug loading.) <P>COPYRIGHT: (C)2012,JPO&INPIT |
