Technical difficulties and challenges include the tendency of the MRI-visible lesion to fade over time (because enhancement with contrast material is transient). [5] In addition, because of the amount of time required to perform the procedure (30-60 min), the patient may begin to move, which could cause an error in needle placement. Nevertheless, MRI localizations have generally been as accurate as mammographic localizations, with miss rates of 2-9%. Some investigators have suggested that postoperative MRI should be performed to verify complete excision of the lesion.
