Magnetic resonance imaging of the breast was performed on 25 lesions in 24 patients. These lesions were indeterminate on clinical and mammographic examination. The imaging findings were compared with pathological results in all cases. Conventional T1 and T2 spin echo images provided a certain diagnosis in only one case. The pattern of signal enhancement following gadolinium diethylamine triamine pentaacetic acid injection as demonstrated by a T1-weighted gradient recalled echo sequence permitted accurate diagnosis of four recurrent carcinomas and 19 cases of non-malignant disease (17 postoperative scars and two cases of benign breast disease). One false positive diagnosis of cancer was made in a case of fibroadenoma. Dynamic contrast enhanced magnetic resonance imaging may have a role in the assessment of the indeterminate breast mass.
对24例患者的25个病灶进行了乳腺磁共振成像检查。这些病灶在临床和乳腺钼靶检查中均难以明确诊断。所有病例均将影像学检查结果与病理结果进行了对比。常规T1和T2自旋回波图像仅在1例中做出了明确诊断。钆喷酸葡胺注射后，T1加权梯度回波序列所显示的信号增强模式能够准确诊断4例复发性癌以及19例非恶性疾病（17例术后瘢痕和2例乳腺良性疾病）。1例纤维腺瘤被误诊为癌症。动态对比增强磁共振成像在评估难以明确的乳腺肿块方面可能具有一定作用。
