摘要
目的：探讨乳腺评估容积成像（VIBRANT）动态增强MR在乳腺良恶性肿块病变中的诊断价值。方法选择98例乳腺肿块患者，均接受双侧乳腺钼靶X线摄影和VIBRANT动态增强MR检查，比较两种方法诊断乳腺良恶性肿块的灵敏度、特异度、阳性预测值、阴性预测值及诊断符合度。结果共113枚病灶，经病理诊断为恶性57例65枚病灶，良性41例48枚病灶。其中，钼靶X线摄影诊断的灵敏度、特异度、阳性预测值和阴性预测值分别为67．69％（44／65）、68．75％（33／48）、74．58％（44／59）和61．11％（33／54），VIBRANT动态增强MR诊断的灵敏度、特异度、阳性预测值和阴性预测值分别为84．62％（55／65）、89．58％（43／48）、91．67％（55，60）和81．13％（43／53）。两种方法诊断符合度比较差异有统计学意义（P＜0．05）。结论VIBRANT动态增强MR在乳腺良恶性肿块病变中的诊断价值高于钼靶x线摄影。
Objective To investigate the diagnostic value of volume imaging for breast assessment （VIBRANT） dynamic enhanced MR for benign and malignant breast mass. Methods Ninety-eight patients with breast mass underwent both bilateral molybdenum target radiography and VIBRANT dynamic enhanced MR examination. The sensitivity,specificity,positive predictive value, negative predictive value and diagnosis accuracy between two methods were compared. Results There were 113 lesions including 65 lesions in 57 malignant cases and 48 lesions in 41 benign cases. The sensitivity,specificity,positive predictive value and negative predictive value of molybdenum target radiography were 67.69% （44/65）, 68.75% （33/48）,74.58% （44/59） and 61.11% （33/54）,respectively. The values of VIBRANT dynamic enhanced MR were 84.62% （55/65）, 89.58% （43/48）, 91.67% （55/60） and 81.13% （43/53）, respectively. The difference of the diagnosis accuracy between two methods had statistical significance （P 〈0.05）. Conclusion The diagnostic value of VIBRANT dynamic enhanced MR for benign and malignant breast mass is higher than molybdenum target radiography.
