Abstract : This study explored whether microscopic magnetic resonance imaging (MRI) could help to determine the nature of suspicious breast lesions. After mammography identifies a suspicious lesion, there is currently no reliable, noninvasive way to determine whether the lesion is malignant, which results in unnecessary biopsies. In this study, we developed a special set-up, to be used in a GE Signa 1.5F magnet. The breast was gently compressed and small receiver coils were used to detect the MR signal to produce very high resolution images of the breast lesions. Using these coils, as well as a contrast agent, several types of images were obtained for all patients. There were 6 patients, all of whom underwent biopsies, and the biopsy results were compared with the acquired images.
