Using MRI for diagnosis could help prevent breast cancer progression
... method of detection was assessed by comparing the biological profiles of mammography-detected DCIS with those of MRI-detected DCIS. The researchers found that of 167 women who had a diagnosis of DCIS, 153 (92%) were diagnosed by MRI compared with 93 (56%) diagnosed by mammography.
