摘要
目的:探讨MRI多项技术在乳腺良、恶性病变诊断中的临床应用价值。方法:对39例乳腺疾病患者行T1WI、抑脂T2WI、动态增强(DCE-MRI)、弥散加权成像(DWI)扫描。使用后处理软件测量表观弥散系数(ADC值)、绘制时间一信号强度曲线。评价上述方法对乳腺疾病的定性诊断价值。结果:39例患者中,共43个病灶,恶性30例,良性13例。常规MR成像、动态增强成像诊断乳腺病变的敏感性分别为73.3%(22/30),86.7%(26/30),特异性为61.5%(8/13),69.2%(9/13),准确率为69.8%(30/43),81.4%(35/43)。ADC值诊断及联合诊断的敏感性为分别93.3%(28/30),83.3%(25/30),特异性为76.9%(10/13),84.6%(11/13),准确性为88.4%(38/43)83.7%(36/43)。结论:乳腺磁共振多项技术联合应用,可提高病变诊断的特异性,对乳腺良、恶性病变的诊断有重要临床价值,并且为临床制定治疗、手术方案提供重要的依据。
Objective： To evaluate the clinical value of MRI multiple technology analysis diagnosis of breast benign and malignant lesions. Methods：39 cases patient of breast disease all received double -breast axial T1 WI,T2WI series axial fat - pressure series and ax- ial diffusion weighted imaging（DWI） scan ,dynamic contrast -enhanced scan. Using postl processing software to obtain the measurement of Apparent Diffusion Coefficient（ ADC value） ,time signal strength curves. The validities of all the above methods were evaluated. Results： The sensitivity, speetivity, and accuracy of MRI rout - scanning and dynamic contrast - enhanced imaging respectively were73.3% （22/ 30 ） ,86.7% （26/30） ,61.5% （ 8/13 ） and 69.2% （9/13） ,69.8 （ 30/43 ） , 81.4% （ 35/43 ） respectively. The senificity, spectivity, and accuracy of ADC for were 93.3% （28/30） ,76.9% （ 10/13 ） ,88.4% （38/43）respectively. Tile senificity, spe -etivity, and accuracy of combination of dynamic contrast - enhanced MRI and DWI - ADC were 83.3% （ 25/30 ） , 84.6 （ 11/13 ） and83.7 % （ 36/43 ） respectively. Conclusion：The combination of MRI multiple technology is useful to increase specificity, all of the inspection method has important value in the diagnosis od breast benign and malignant lesions.
