128排上腹部增强多层螺旋CT在小肝癌诊断中的研究

Study on the Efficacy of 128-Slice Upper Abdominal Enhanced Multilayer Spiral CT in the Diagnosis of Small Hepatocellular Carcinoma

目的探讨128排上腹部增强多层螺旋CT在小肝癌诊断中的效能。方法选取新乡市第一人民医院2021年1月至2023年10月收入的72例疑似小肝癌患者,所有患者均接受128排上腹部增强多层螺旋CT、MRI检查,并以病理结果为金标准,对比两者诊断效能。结果72例疑似小肝癌患者经病理检查结果显示53例为恶性(73.61%)、19例为良性(26.39%),128排上腹部增强多层螺旋CT中诊断准确率为94.44%,高于MRI的准确率(81.94%),差异有统计学意义(P<0.05);72例疑似小肝癌患者中,经病理明确病灶大小,病灶直径<2 cm为14例、2~5 cm为34例、>5 cm为24例。MRI与128排上腹部增强多层螺旋CT明确病灶大小情况,差异无统计学意义(P>0.05);53例小肝癌患者中,33例为肝细胞癌、8例为胆管细胞癌、6例为混合细胞癌、6例为转移性肝癌,MRI与128排上腹部增强多层螺旋CT肝癌类型确诊情况,差异无统计学意义(P>0.05)。结论128排上腹部增强多层螺旋CT疾病诊断准确率高于MRI检查,且在病灶大小确诊及肝癌类型确诊中具有较高的诊断效能,能用于临床疾病早期诊断,为临床医师诊疗方案的实施提供合理依据。

Objective To explore the efficacy of 128-slice upper abdominal enhanced multilayer spiral CT in the diagnosis of small hepatocellular carcinoma.Methods 72 suspected small hepatocellular carcinoma patients admitted to The First People’s Hospital of Xinxiang City from January 2021 to October 2023 were selected.All patients underwent 128-slice upper abdominal enhanced multilayer spiral CT and MRI examinations,and the diagnostic efficacy of the two was compared with pathology results as the gold standard.Results Pathological examination results of 72 suspected small hepatocellular carcinoma patients showed that 53 cases were malignant(73.61%)and 19 cases were benign(26.39%).The diagnostic accuracy rate of 128-slice upper abdominal enhanced multilayer spiral CT was 94.44%,which was higher than the accuracy rate of MRI(81.94%),and the difference was statistically significant(P<0.05).Among the 72 suspected small hepatocellular carcinoma patients,the lesion size was confirmed by pathology,with 14 cases of lesion diameter<2 cm,34 cases of 2~5 cm,and 24 cases of>5 cm.There was no statistical significance in the determination of lesion size by MRI and 128-slice upper abdominal enhanced multilayer spiral CT(P>0.05).Among the 53 small hepatocellular carcinoma patients,33 cases were hepatocellular carcinoma,8 cases were cholangiocarcinoma,6 cases were mixed cell carcinoma,and 6 cases were metastatic liver cancer.There was no statistical significance in the diagnosis of liver cancer type by MRI and 128-slice upper abdominal enhanced multilayer spiral CT(P>0.05).Conclusion The disease diagnostic accuracy rate of 128-slice upper abdominal enhanced multilayer spiral CT is higher than that of MRI examination,and it has a higher diagnostic efficacy in the determination of lesion size and liver cancer type.It can be used for early clinical disease diagnosis and provide a reasonable basis for the implementation of clinical treatment plans by clinicians.
