A method and system for performing biopsies can include an imaging system (190) for obtaining diagnostic images of a target region (200); a tracking system (100); a probe (75) having a deployable biopsy needle for performing a biopsy procedure where the tracking system generates tracking information for at least one of the probe and the biopsy needle; an ultrasound imaging system (50) for obtaining ultrasound imaging of the target region; and a computer (150) in communication with the tracking system, the imaging system and the ultrasound imaging system. The computer can register the tracking system with the imaging system. The computer transfers a marking (500) of a biopsy site associated with the biopsy procedure from the ultrasound imaging to the diagnostic images based on the tracking information and the registration of the tracking system with the diagnostic images.
