Provided is a fluoroscopy apparatus including an illumination unit that radiates illumination light and excitation light onto a subject a fluorescence imaging unit that acquires a fluorescence image by imaging fluorescence generated at the subject a return-light imaging unit that acquires a return-light image by imaging return light returned from the subject a fluorescence-image storage unit that stores the fluorescence image a treatment input unit to which signals for starting and ending treatment performed on the subject are input a comparison-image generating unit that generates a comparison image that enables comparison of the fluorescence image stored in the fluorescence-image storage unit when the signal for starting the treatment is input to the treatment input unit and the fluorescence image acquired when the signal for ending the treatment is input and a display unit that displays the comparison image.
