A diagnostic imaging device is provided to detect cancers in early stages with a high degree of accuracy while minimizing the risk of X-ray exposure that can be caused by the X-ray CT examination, taking advantage of the PET examination which provides a means of efficient early detection of cancers while minimizing the risk of radiation exposure. A PET gantry 20 and a CT gantry 30 are arranged sequentially relative to a common examination table 10 , a control unit provided in a console 40 controlling the examination table 10 , the PET gantry 20 , and the CT gantry 30 , and an examination subject 13 laid on a top board 11 of the examination table 10 is inserted into a tunnel 21 of the PET gantry 20 for collecting PET data in order to reconstruct a PET image, display the PET image on an image monitor provided in the console 40 , allow a doctor to make a determination as to whether the examination subject 13 should be further subjected to a CT examination by sending it into a tunnel 31 of the CT gantry 30 , and allow necessary actions to be taken in accordance with the determination.
