Answer

Answer

Normal tissues do not significantly alter their enhancement after routine needle biopsy. Foci of hemorrhage or a focal hypointense ferromagnetic metal artifact are occasionally seen at the biopsy site, particularly on GRE images. The biopsy clip is best visualized on T1 non-fat saturation images. Postbiopsy changes, including the biopsy tract, may be visualized in cases with recent biopsy.
