The present invention relates to a multimodal system for obtaining senological images by means of X-ray and MBI techniques. Said multimodal system comprises: - a supporting plane (1) for the breast, - a gamma ray detector (2A) for obtaining at least a molecular image, - a detection module (10) comprising inside said gamma ray detector (2A), where said gamma ray detector (2A) is arranged on a first plane, parallel to said supporting plane, as well as: o at least one between an X-ray detector (4) for obtaining at least an X-ray image and a scintigraphic collimator (2B)； said scintigraphic collimator (2B), when in use, being coupled with said gamma ray detector (2A) and forming with said gamma ray detector (2A) a first gamma camera (2)； o a compartment (3) configured for receiving one at time said X- ray detector (4) or said scintigraphic collimator (2B), where said compartment (3) is arranged between said supporting plane (1) and said gamma ray detector (2A) on a second plane, parallel to said supporting plane (1), different from said first plane.
