| 摘 要： | 对52例乳腺病变患者进行MRI动态增强扫描。在MRI血管图上进行血管计数，计数评价分为0～3级。平均乳腺血管数M，乳腺恶性病变患侧为（3．8±2．0）条，良性病变患侧为（1．3±1．0）条，良恶性病变间差异有统计学意义（P〈0．05）。采用0～1级诊断为良性病灶，2～3级诊断为恶性病灶标准，特异度为79％，敏感度为83％。乳腺癌患侧乳腺血管数目明显增多，可为MRI诊断乳腺癌提供更多的信息。

| Abstract: | Total 52 patients with breast lesions underwent dynamic contrast-enhanced breast MRI; and the breast vascularization was scored on the MRI vascular maps with a range of 0 to 3. The mean number of vessels per ipsilateral breast in malignant cases was higher than that of benign cases (3.8±2.0 vs. 1.3± 1.0; P=0.000). When the breast vascularity score 0-1 was defined as benign and 2-3 was defined as malignant, the sensitivity and specificity was 79% and 83%, respectively. Results indicate that dynamic contrast-enhanced breast MRI is of value in diagnosis of malignant breast lesions. |
