Fusion of 3D images with real-time ultrasound
During the biopsy, 3-dimensional information derived from the multi-parametric MRI is color-coded and fed into an innovative guidance and imaging device that fuses the images with real-time ultrasound (MR-US fusion). This blending of images provides a map of the prostate and areas of suspicion for needle navigation and permits direct targeting of the lesion in question.
Moreover, lesions outside the normal catchment area of conventional biopsies can be identified. Once mapping and targeted biopsy have identified a tumor suitable for active surveillance, follow-up typically requires fewer biopsy samples than standard biopsy.
Teams from the National Institutes of Health pioneered targeted biopsy in 2009. Research at UCLA has improved image fusion technology, and UCLA clinicians have now performed more than 900 targeted biopsies — more than any other institution.
