Task: Answer Verification
Input (English): Question: Is perioperative breast MRI associated with lower locoregional recurrence rates in DCIS patients treated with or without radiation?
Answer: We observed no association between perioperative MRI and lower LRR or CBC rates in patients with DCIS, with or without RT. In the absence of evidence that MRI improves outcomes, the routine perioperative use of MRI for DCIS should be questioned.
Output (English): no
