MRI动态增强TIC类型及ADC值在乳腺癌诊断中的价值

The value of dynamic contrast-enhanced MRI time-intensity curve type and apparent diffusion coefficient in the diagnosis of breast cancer

目的:探讨MRI动态增强时间-信号曲线(TIC)类型及表观扩散系数(ADC)在乳腺癌的诊断及鉴别诊断中的价值。方法:回顾性分析2015年1月-2019年6月期间行乳腺MRI检查,且经组织病理学确诊的乳腺病变患者70例,其中乳腺癌38例,良性病变32例,分析其TIC类型及测量ADC值。结果:良性病灶组中以I型曲线多见,乳腺癌组中以Ⅲ型曲线多见,两类曲线对于良恶性乳腺病变的鉴别差异有统计学意义(P<0.01)。良性病变组患者ADC值明显大于乳腺癌组,差异具有统计学意义(P<0.01)。结论:MRI动态增强时间-信号曲线及表观扩散系数在乳腺癌的诊断及鉴别诊断中具有很高的应用价值。

Objective:To discuss the value of MRI time-intensity curve(TIC)type and apparent diffusion coefficient(ADC)in diagnosis and differential diagnosis of breast cancer.Methods:70 cases of breast lesions which were examined by MRI and confirmed by histopathology between January 2015 and June 2019 were analyzed,retrospectively,38 cases of breast cancer and 32 cases benign lesions included.The TIC type and ADC value were recorded.Results:The statistical results show that type I curve was more common in benign lesions while type III curve in breast cancers.The two types of curve were significantly different in two groups(P<0.05).ADC value of benign lesion group was significantly higher than breast cancer group(P<0.05).Conclusion:MRI dynamic enhancement TIC type and ADC value have a high application value in the diagnosis and differential diagnosis of breast cancer.
