摘要
目的探讨磁共振多b值技术在鉴别肝脏局灶性病变中的应用价值,提高对肝脏局灶性病变的正确诊断率。方法选取我院2016年9月~2018年10月行磁共振检查的肝脏占位病变75例患者为研究对象,其中恶性病变患者40例,良性病变患者35例。同时选取同期健康志愿者30名在GE MR750引导下行MR扫描,记录多b值扩散加权成像不同性质肝脏局灶性病变的信号强度、ADC值,观察不同性质病变的b值-信号强度和b值-ADC值曲线的差异、特点。结果肝脏局部良性病变者与肝脏局部恶性病变者的肝脏局灶性病变的信号强度、ADC值,不同性质病变的b值-信号强度和b值-ADC值曲线均有显著性差异(P<0.05)。结论通过MRI扫描序列的设立及多b值的测算,对扫描结果进行综合分析、判断,可鉴别肝脏不同性质局灶性病变的性质,提高正确诊断率,具有较好的诊断价值。
Objective To explore the application value of Multi-b value MRI in the differential diagnosis of liver focal lesions, so as to improve the correct diagnosis rate of liver focal lesions. Methods From September 2016 to October 2018, 75 patients with liver space occupying lesions were selected as the study object, including 40 patients with malignant lesions and 35 patients with benign lesions. At the same time, 30 healthy volunteers under the guidance of Ge MR750 were selected for MR scanning to record the signal intensity and ADC value of liver focal lesions of different natures on multi-b-value diffusion weighted imaging, and to observe the differences and characteristics of b-value signal intensity and b-value ADC value curves of different natures of lesions. Results There were significant differences in signal intensity, ADC value, b-value-signal intensity and b-value-ADC value curves between benign and malignant lesions(P<0.05).Conclusion Through the establishment of MRI scanning sequence and the calculation of Multi-b value, the comprehensive analysis and judgment of the scanning results can identify the nature of focal lesions of different nature of the liver, improve the correct diagnosis rate, and have better diagnostic value.
