Abstract

One or both breasts of 296 patients with equivocal clinical or mammographic findings were examined with MRI. T1-weighted spin-echo (SE) and gradient-echo (FFE) sequences were acquired before and after i.v. application of Gadolinium DTPA. 50 lesions with enhancement after Gd-DTPA were biopsied--26 carcinomas, 17 proliferating mastopathic tissues, 5 fibroadenomas and 1 abscess were found. Contrast enhanced MRI with 2D-SE and FFE sequences is an effective technique for evaluating suspicious breast lesions with high diagnostic accuracy.

摘要

对296例临床或乳腺X线摄影检查结果不明确的患者的一侧或双侧乳房进行了MRI检查。在静脉注射钆喷酸葡胺前后，采集了T1加权自旋回波（SE）和梯度回波（FFE）序列。对50个钆喷酸葡胺注射后有强化的病变进行了活检，发现26例为癌，17例为增生性乳腺病组织，5例为纤维腺瘤，1例为脓肿。采用二维SE和FFE序列的对比增强MRI是一种评估可疑乳腺病变的有效技术，诊断准确性高。
