Radiopathological correlations: masses, non-masslike enhancements and MRI-guided biopsy.
MRI-guided biopsy is a recent interventional breast technique. Validating the procedure poses a new problem because the signal targeted is created by the injection of a paramagnetic contrast agent and is thus transitory. In the first instance, the procedure is validated by the radiologist, who checks that targeting is accurate and inserts a clip at the end of the procedure, and secondly by analysis of the histopathological results, which should be representative of the lesion. The pathologist needs to know the nature of the image, i.e. whether it is of mass or non-masslike enhancement, and its BI-RADS classification. The objective is that the image and the pathological result should concur. If the result is non-specific and benign, a follow-up MRI is required six months later.
