【摘要】：目的探讨高场MRI对乳腺X线摄影可疑钙化良、恶性病变的鉴别诊断价值。方法 2012年10月至2014年4月该院乳腺X线检查表现可疑钙化患者48例52个病灶,所有病例术前MRI平扫及动态增强,X线引导下钩丝定位后手术切除,对手术标本行钼靶X线摄影,观察病变是否完整切除;以病理结果为金标准,分析乳腺X线摄影及MRI表现与病理结果的相关性。结果 48例52个病灶,乳腺X线检查美国放射学会乳腺影像报告和数据系统(BI-RADS)3类13个,4类39个;MRI检查评估为BI-RADS-MRI 1类19个,2类1个,3类8个,4类13个,5类11个;病理诊断:良性40个,恶性12个;MRI对可疑钙化恶性病变的灵敏度为100.0%,特异度为70.0%,准确性为76.9%,阴性预测值为100.0%,阳性预测值为50.0%;乳腺X线摄影对可疑钙化恶性病变的阳性预测值及准确性均为23.1%,二者差异有统计学意义(χ2=5.51,P0.05;χ2=30.15,P0.01)。结论高场MRI对乳腺X线摄影发现的可疑钙化良、恶性病变有较好的鉴别诊断价值,可提高活检恶性阳性率。
[Abstract]:Objective to investigate the value of high field MRI in differential diagnosis of suspected calcification and malignant lesions in mammography.Methods from October 2012 to April 2014, 48 patients (52 lesions) with suspected calcification were examined by mammography. All the patients were resected by MRI plain scan and dynamic contrast enhanced radiography-guided hookwire localization. Molybdenum target radiography was performed on the specimens.The correlation of mammography and MRI findings with pathological findings was analyzed.Results in 48 patients with 52 lesions, the mammography report and data system of the American Society of Radiography (ARS) were evaluated as BI-RADS-MRI 1, 19, 2, 8, 4, 13, 13, 5, 11, and the data system was evaluated as BI-RADS3, class 3, class 3, class 2, class 1, class 2, class 3, class 3, class 4, class 13, class 5, type 11.Pathological diagnosis: benign 40,The sensitivity, specificity, accuracy, negative predictive value, positive predictive value and positive predictive value of 12 MRI images for suspected calcified malignant lesions were 100.0, 70.0, 76.9and 100.0.The positive predictive value and accuracy of mammography for suspected calcified malignant lesions were both positive and accurate.There was significant difference between the two groups (蠂 2, 5.51, P 0.05; 蠂 2, 30.15, P 0.01; 蠂 2, 30.15, P 0.01).Conclusion High field MRI has a good value in differential diagnosis of suspected calcification and malignant lesions found by mammography, and can improve the positive rate of biopsy.
