RESUMO
MR imaging-guided focal therapy is a viable treatment option for patients with localized prostate cancer. After the identification of a malignant focus in the prostate gland on multiparametric MR imaging, treatment can be directed in a precise fashion to the area of interest. The goal of focal therapy is to eradicate prostate cancer while minimizing complications that can affect quality of life. Currently, the most commonly used methods of focal treatment of prostate cancer are cryotherapy, high-intensity focused ultrasound, and laser ablation.

MR imaging is now routinely performed for breast cancer screening and staging. For suspicious MR imaging-detected lesions that are mammographically and sonographically occult, MR imaging-guided breast interventions, including biopsy, clip placement, and preoperative needle localization, have been developed to permit accurate tissue diagnosis and aid in surgical planning. These procedures are safe, accurate, and effective when performed according to key principles, including proper patient selection, use of appropriate technique, adequate preprocedure preparation and postprocedure patient care, and postprocedure imaging-pathology correlation. Imaging-pathology correlation after MR imaging-guided biopsy is essential to confirm accurate sampling and guide development of a comprehensive management plan.

Contrast-enhanced breast MR imaging is increasingly being used to diagnose breast cancer and to perform biopsy procedures. The American Cancer Society has advised women at high risk for breast cancer to have breast MR imaging screening as an adjunct to screening mammography. This article places special emphasis on biopsy and operative planning involving MR imaging and reviews use of breast MR imaging in monitoring response to neoadjuvant chemotherapy. Described are peer-reviewed data on currently accepted MR imaging-guided procedures for addressing benign and malignant breast diseases, including intraoperative imaging.
