摘　　要：目的:探讨64排螺旋CT后处理技术在肝癌及肝硬化疾病诊断中的价值。方法:选取中南大学湘雅医院2020年1月—2021年2月收治并经手术病理或穿刺确诊的肝硬化患者55例与肝癌患者57例,并选取同期经我院临床及影像证实的肝血管瘤患者112例。所有患者均接受超声及64排螺旋CT后处理技术检查。统计不同检查方式临床检出情况,分析64排螺旋CT后处理诊断敏感度、特异度与准确性情况及影像表现。结果:肝硬化检查中,64排螺旋CT后处理技术的阳性检出率为98.18%,阴性检出率为100.00%,与手术探查结果相比差异不显著(P>0.05);64排螺旋CT后处理技术的阳性检出率与阴性检出率均显著高于超声检查(P<0.05)。在肝癌检查中,64排螺旋CT后处理技术的阳性检出率为98.25%,阴性检出率为100.00%,与手术探查结果相比差异不显著(P>0.05);64排螺旋CT后处理技术的阳性检出率及阴性检出率均显著高于超声检查(P<0.05)。肝硬化检查与肝癌检查中,64排螺旋CT后处理技术的敏感度、特异度与准确性均较高。64排螺旋CT扫描检查后图像处置技术较为清晰地提示了肝癌肿瘤与周边血管壁的毗邻情况。结论:64排螺旋CT后处理技术的临床应用能更好地鉴别诊断肝癌及肝硬化,为临床治疗提供了较为充分的依据。建议在临床检查中推广、使用。Objective To evaluate the value of 64-row spiral CT in the diagnosis of liver cancer and cirrhosis.Methods 55 patients with liver cirrhosis and 57 patients with liver cancer who were admitted to Xiangya Hospital of Central South University from January 2020 to February 2021 and confirmed by surgical pathology or puncture were selected.112 patients with hepatic hemangioma confirmed by clinical and imaging in our hospital during the same period were selected.All patients were examined by ultrasound and 64-row spiral CT.The clinical findings of different examination methods were counted,the diagnostic sensitivity,specificity and accuracy and imaging performance of 64-row spiral CT post-processing technology were analyzed.Results In liver cirrhosis examination,the positive rate of 64-row spiral CT was 98.18%,and the negative rate was 100.00%,the results of surgical exploration were not significantly different compared to those(P>0.05).However,the positive and negative detection rates of 64-row spiral CT were significantly higher than those of ultrasound(P<0.05).In liver cancer examination,the positive rate of 64-row spiral CT was 98.25%,and the negative rate was 100.00%,which showed no significant difference compared with surgical exploration(P>0.05).However,the positive and negative detection rates of 64-row spiral CT were significantly higher than those of ultrasound(P<0.05).The sensitivity,specificity and accuracy of 64-row spiral CT post processing are high in liver cirrhosis and liver cancer examination.The image processing technology after 64-row spiral CT scan can clearly indicate the adjacent situation of liver cancer tumor and peripheral vascular wall.Conclusion The clinical application of 64-row spiral CT can better differentiate liver cancer and liver cirrhosis,and provide a more sufficient basis for clinical treatment.It is recommended to be popularized and used in clinical examination.
