Abstract
A cerebral blood flow rate quantification device includes: a nuclear medicine image acquisition unit for acquiring a nuclear medicine image of the head of a subject administered with a radiopharmaceutical; a count calculation unit for calculating the number of counts obtained from a unit region; a cerebral blood flow rate calculation unit for calculating the value of a cerebral blood flow rate that makes the value of a function, which expresses the concentration of the radiopharmaceutical in brain tissue; and a cerebral blood flow map generation unit for generating a map showing cerebral blood flow based on the cerebral blood flow rate in each unit region. Consequently, the cerebral blood flow rate can be accurately quantified even at a relatively early stage after administration of a radiopharmaceutical.
