MSCT联合弥散加权成像用于原发性肝癌患者的诊断价值

Diagnostic Value of MSCT Combined with Diffusion Weighted Imaging in Patients with Primary Liver Cancer

目的探索MSCT联合弥散加权成像对原发性肝癌的诊断价值。方法选取2022年3月-2023年11月在我院诊治的66例疑似原发性肝脏肿瘤患者为研究对象,均采用多层螺旋CT(MSCT)、弥散加权成像(DWI)诊断,以病理诊断结果为金标准,观察不同诊断方法对不同类型患者、不同病理分期患者的检出率以及诊断效能,比较MSCT与DWI联合及单独诊断原发性肝癌的价值。结果MSCT+DWI检查操作时间长于DWI、MSCT,病情确诊时间短于DWI、MSCT(P<0.05),但DWI检查操作时间、病情确诊时间与MSCT比较,差异无统计学意义(P>0.05);MSCT+DWI诊断灵敏度与DWI、MSCT比较,差异无统计学意义(P>0.05),MSCT+DWI诊断特异度、准确度均高于DWI、MSCT(P<0.05),但DWI特异度、准确度与MSCT比较,差异无统计学意义(P>0.05);MSCT+DWI诊断检出病灶数、直径的准确率均大于DWI、MSCT(P<0.05),但DWI与MSCT比较,差异无统计学意义(P>0.05);ROC曲线显示,MSCT+DWI诊断原发性肝癌的AUC面积大于DWI、MSCT(P<0.05),但DWI与MSCT比较,差异无统计学意义(P>0.05)。结论MSCT联合弥散加权成像诊断原发性肝癌具有相对较高的价值,可提高特异度、准确度,降低漏诊或误诊率,且利于病灶数和直径的准确检出,可为临床早期治疗提供可靠的参考。

Objective To explore the diagnostic value of MSCT combined with diffusion weighted imaging in primary liver cancer.Methods A total of 66 patients with suspected primary liver tumors diagnosed and treated in our hospital from March 2022 to November 2023 were selected as the research objects.All patients were diagnosed by multi-slice spiral CT(MSCT)and diffusion-weighted imaging(DWI).The pathological diagnosis results were used as the gold standard.The detection rate and diagnostic efficacy of different diagnostic methods for different types of patients and patients with different pathological stages were observed.The value of MSCT combined with DWI and single diagnosis of primary liver cancer was compared.Results The operation time of MSCT+DWI was longer than that of DWI and MSCT,and the diagnosis time was shorter than that of DWI and MSCT(P<0.05),while there was no significant difference in the operation time and diagnosis time between DWI and MSCT(P>0.05).There was no significant difference in diagnostic sensitivity between MSCT+DWI and DWI,MSCT(P>0.05),but the diagnostic specificity and accuracy of MSCT+DWI were higher than those of DWI and MSCT(P<0.05),however,there was no significant difference in specificity and accuracy between DWI and MSCT(P>0.05).The accuracy of the number and diameter of lesions detected by MSCT+DWI was higher than that of DWI and MSCT(P<0.05),but there was no significant difference between DWI and MSCT(P>0.05).ROC curve showed that the AUC area of MSCT+DWI in the diagnosis of primary liver cancer was larger than that of DWI and MSCT(P<0.05).Conclusion MSCT combined with diffusion weighted imaging has a relatively high value in the diagnosis of primary liver cancer,which can improve the specificity and accuracy,reduce the rate of missed diagnosis or misdiagnosis.Meanwhile,it is conducive to the accurate detection of the number and diameter of lesions,which can provide a reliable reference for early clinical treatment.
