Abstract

Thirty‐five women with a total of 39 breast lesions detected at mammography and/or physical examination and who were scheduled for surgical biopsy were studied with dynamic magnetic resonance (MR) mammography. Fat‐suppressed, spoiled GRASS (gradient‐recalled acquisition in the steady state) sequences were performed before and after administration of gadopentetate dimeglumine. T1‐weighted spin‐echo and fat‐suppressed T2‐weighted fast spin‐echo images were also obtained. By measuring percentage signal intensity change in lesions on the spoiled GRASS images after contrast agent injection, the authors achieved a sensitivity of 100% and a specificity of 83.3% in differentiating benign from malignant lesions (24 benign, 15 malignant), with biopsy results as the standard. This dynamic MR mammography technique deserves further evaluation.
