<p>PURPOSE:To provide the quantitative value data on the in vivo function such as the glucose consumption rate and cerebral blood flow without collecting blood from the artery of a subject. CONSTITUTION:An auxiliary detector 22 movable in the body axis direction of a subject 10 near a radiation detector 1 and detecting radioactive rays from an artery blood portion 26 separately from the inspection portion by the radiation detector 1 is provided, and a separate simultaneous counting circuit 23 and a high-speed memory 24 inputting and calculating the detection signal from the auxiliary detector 22 are provided. The quantitative value data on the in vivo function can be obtained while no blood is collected from the subject 10.</p> |
