PROBLEM TO BE SOLVED: To maintain a radiation detector at a predetermined temperature or lower, to suppress temperature variations among individual radiation detectors, to improve time resolution and energy resolution, and to improve the diagnostic accuracy. SOLUTION: Nuclear medicine diagnostic equipment has an imaging apparatus, having an instrumentation space section K into which a specimen H is to be inserted. The imaging apparatus comprises a detector unit 20, that has a plurality of radiation detectors 21 and signal processors and is arranged around the instrumentation space section K, and inlet sections 30 and discharge sections 40 divided by partitions 50. A medium for cooling introduced into the inlet sections 30 cools the signal processor and is then discharged to the discharge sections 40 partitioned by the partitions 50.
