Postbiopsy Confirmation of MR-Detected Lesions Biopsied Using Ultrasound
American Journal of Roentgenology, 05/31/2012
Monticciolo DL – Ensuring that a lesion seen on targeted ultrasound is the same as that detected at MRI can be difficult. For benign concordant lesions, a mismatch may only be discovered at 6–month postbiopsy MRI follow–up. However, lesion correlation can be established on the same day as biopsy by obtaining a single unenhanced T1–weighted non–fat–saturated pulse sequence just after percutaneous ultrasound–guided biopsy. Scanning time is less than 4 minutes. Postbiopsy changes and the biopsy clip are easily seen and help verify MR–sonographic lesion correlation.
