MRI、MSCT三期增强对肝脏孤立性结节的鉴别诊断研究

Differential Diagnosis Value of MRI and MSCT Three-Phase Enhanced Scan for Solitary Liver Nodules

目的旨在分析MRI、MSCT三期增强对肝脏孤立性结节的鉴别诊断价值。方法回顾分析本院2017年3月至2019年5月收治的肝脏孤立性结节患者的临床资料56例,所有患者均经病理检查确诊。对患者所得MSCT及MRI图像进行分析,并以病理结果为基础对比MSCT、MRI对肝脏孤立性结节良、恶性结节检出率以及病变检诊断合率。结果MSCT对肝脏孤立性结节良、恶性检出率分别为68.00%、90.32%,MRI为64.00%、93.54%,两者与比较,差异无统计学意义(P>0.05)。以病理结果为基准,MSCT检查对肝脏孤立性结节良、恶性诊断符合率分别为48.00%、64.51%,均低于MRI检查(80.00%、90.32%)(P<0.05)。结论MRI、MSCT三期增强对肝脏孤立性结节的鉴别诊断均有较高应用价值,但MRI提供信息更为全面,可提高诊断符合率,值得临床推广。

Objective To analyze the differential diagnosis value of MRI and MSCT three-phase enhanced scan for solitary liver nodules.Methods The clinical data of 56 patients with solitary liver nodules admitted to our hospital from March 2017 to May 2019 were retrospectively analyzed.All patients were diagnosed by pathological examination.The MSCT and MRI images of the patients were analyzed.The pathological results were used as a basis to compare the detection rate of benign and malignant nodules in solitary liver nodules and the accuracy in the diagnosis of lesions between MSCT and MRI.Results The detection rates of MSCT for benign and malignant liver nodules were 68.00%and 90.32%,respectively,and detection rates of MRI was 64.00%and 93.54%.There was no significant difference between the them(P>0.05).The pathological results were used as a basis,the accuracy of MSCT examination in the diagnosis of benign and malignant liver nodules was 48.00%and 64.51%,respectively,which were lower than those of MRI(80.00%,90.32%)(P<0.05).Conclusion MRI and MSCT three-phase enhanced scan have high application value in the differential diagnosis of solitary nodules of the liver.However,MRI provides more comprehensive information,which can improve the diagnostic accuracy and it is worthy of clinical promotion.
