Answer

Answer

Early postoperative MRI is affected by the strong enhancement of resection margins in response to inflammatory postoperative reactions. Therefore, MRI is unable to exclude possible residual tumor until at least 12-18 months after completion of BCT. However, MRI is often used as part of the routine posttreatment follow-up, because it can discriminate between postsurgical tissue modifications and tumor relapse with a high negative predictive value and a sensitivity of 90-100% and a specificity of 89-92%.
