MR directed breast biopsy is an essential component of any breast program which includes breast MR. However, it can be very diifficult at times to position patients for biopsy. Further, unlike ultrasound or stereo biopsy, verifying that the targeted lesion has been biopsied is complicated by the fact that 1) the lesion has faded by the time that a post biopsy image is obtained and 2) anesthetic and bleeding obscure the lesions. The wide variety of breast pathology (and even normal tissue) that can demonstrate enhancement complicates the determination of concordant vs discordant pathology even further. This exhibit will review proven “misses” and analyze how the miss occurred and how it may have been recognized.
1)Review of method of MR directed biopsy. 2) Review of cases in which there was a definitive miss of the targeted tissue. 3) Review the common causes of misses and their avoidance 4) Suggest methods to recognize when misses may have occurred.
MR directed biopsy is a necessary component of a comprehensive breast imaging program. Yet, they are much more difficult to perform than stereotactic or ultrasound directed breast biopsies. Given this difficulty, misses are inevitable. This work should aid radiolgists in avoiding misses and then recognizing them when they occur
