Magnetic resonance (MR) imaging of the breast is currently of limited value because of lack of specificity. Enhanced MR imaging with gadolinium diethylenetriaminepentaacetic acid (DTPA) has been shown to be helpful in the further characterization of breast tissue. This prospective study attempted to differentiate benign and malignant breast disease with a dynamic enhancement technique. Bolus injection of Gd-DTPA and a short MR imaging time were used to examine 18 patients with a palpable breast mass. Construction of enhancement profiles helped effectively differentiate benign and malignant lesion (P less than .001). Dynamic MR imaging shows promise for the further characterization of breast tissue and, particularly, identification of breast carcinoma.
由于缺乏特异性，目前乳腺磁共振成像（MR）的价值有限。钆喷酸葡胺（DTPA）增强磁共振成像已被证明有助于进一步鉴别乳腺组织。这项前瞻性研究试图通过动态增强技术区分乳腺良性和恶性疾病。采用钆喷酸葡胺（Gd-DTPA）团注和短磁共振成像时间对18例可触及乳腺肿块患者进行检查。增强曲线的构建有助于有效区分良性和恶性病变（P<0.001）。动态磁共振成像有望进一步鉴别乳腺组织，尤其是识别乳腺癌。
