目的：探讨磁共振(MR)定量及定性参数对乳腺良恶性病灶的鉴别诊断价值。方法对乳腺疾病患者进行动态 MR 检查,并取得病理结果,计算出病灶的时间-信号曲线类型(TIC)、最大上升斜率(Slopemax )、表观扩散系数(ADC)值。结果良性病灶24例,恶性病灶11例。乳腺良性病灶 TIC 类型为Ⅰ型占91.7%(22/24),Slopemax 为0.65%/s,ADC 值为1.31×10-3 mm2/s。乳腺癌 TIC 类型为Ⅱ型和Ⅲ型占100%,Slopemax 为1.63%/s,ADC 值为1.06×10-3 mm2/s。结论 TIC 类型、ADC 值、Slopemax 都对鉴别乳腺疾病良恶性疾病有帮助,如果3项或者2项参数联合起来可以提高诊断的准确性。

Objective To investigate the value of qualitative and quantitative parameters of MRI on diagnosis of benign and malig-nant breast lesions.Methods Patients were scanned with MRI who were confirmed as breast lesions verified by histopathology,and the time-signal curve(TIC),Slopemax ,the apparent diffusion coefficient values (ADC)were deduced.Results There were 24 benign and 11 malignant lesions.Features of benign lesions were shown as follow:The TIC type wasⅠmostly 91.7%,Slopemax was 0.65 %/s,the ADC values was 1.31×10 -3 mm2/s.Features of malignant lesions were shown as follow:The TIC type were Ⅱ and Ⅲ mostly (100%), Slopemax was 1.63 %/s,the ADC values was 1.06 ×10 -3 mm2/s.Conclusion Types of TIC,Slopemax ,the ADC values of MRI are valuable in the diagnosis of benign and malignant breast lesions,integrated functional parameters are better than an individual param-eters in that they can improve the accuracy of diagnosis.
