磁共振动态增强扫描血管图在乳腺癌诊断中的应用
Vascular maps with dynamic contrast-enhanced MRI for diagnosis of breast cancer
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.平均乳腺血管数目,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.
更多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.
