Provided is a fluoroscopy apparatus including illuminating portions that radiate excitation light and illumination light onto an imaging subject； a fluorescence imaging portion that acquires a fluorescence image from fluorescence emitted at the imaging subject due to the irradiation with the excitation light； a return-light imaging portion that acquires a return-light image from return light returning from the imaging subject due to the irradiation with the illumination light； a display portion that displays the acquired fluorescence image and/or the return-light image； an identifying portion that identifies a region-of-interest in the fluorescence image； an image switching portion that switches the display on the display portion so that only the return-light image is displayed thereon when the region-of-interest R is not identified, and so that the return-light image and the fluorescence image are juxtaposed and displayed on the display portion when the region-of-interest has been identified.
