In a new health technology assessment, the U.K. National Institute for Health and Care Excellence (NICE) has voiced misgivings about the evidence behind the use of MRI/ultrasound fusion systems to perform needle biopsy for suspected prostate cancer. NICE said the evidence for these systems could be bolstered by additional research comparing fusion biopsy to cognitive fusion-directed biopsy, suggesting that companies working in this space have a significant evidentiary lift in front of them.
