CT能谱成像对肝脏微小转移瘤的诊断价值

Diagnostic Value of CT Spectrum Imaging on Micrometastases of Liver

摘要

摘要: 目的：探讨肝脏微小转移瘤患者应用CT能谱成像诊断的效果及对患者肝功能的影响。方法：回顾性分析2015年5月至2017年5月我院收治的肝脏微小转移瘤患者80例的临床资料，根据诊断方法不同分成对照组和研究组两组。对照组常规的CT诊断，研究组应用CT能谱成像的诊断方法，对比诊断结果。结果：对比诊断结果，研究组诊断出的病灶个数以及检出率显著高于对照组（&lt;i&lt;P&lt;/i&lt;&lt;0.05），同时漏检率以及误检率均低于对照组（&lt;i&lt;P&lt;/i&lt;&lt;0.05）；研究组应用诊断方法的诊断敏感度、阳性预测值以及特异性都高于对照组（&lt;i&lt;P&lt;/i&lt;&lt;0.05）；对比治疗效果，研究组的疗效显著优于对照组（&lt;i&lt;P&lt;/i&lt;&lt;0.05）。结论：应用CT能谱成像诊断肝脏微小转移瘤患者，有助于疾病早发现、早治疗，有更高的诊断价值，利于患者改善肝功能，值得在临床上推广应用。

Abstract: Objective: The effect of CT spectroscopy in the diagnosis of liver micrometastases and the effect on the liver function of the patients. Methods: Methods 80 cases of hepatic micrometastases in our hospital from May 2015 to May-2017 were retrospective analyzed and divided into two groups according to different diagnostic methods. The control group was given conventional CT diagnosis, and the study group was diagnosed by CT energy spectrum imaging. Results: Comparison of diagnostic results, the number of lesions in study group diagnosed and the detection rate was significantly higher than the control group (&lt;i&lt;P&lt;/i&lt;&lt;0.05), at the same time, loss rate and error rate were lower than the control group (&lt;i&lt;P&lt;/i&lt;&lt;0.05); diagnosis method used in study group the sensitivity, specificity and positive predictive value were higher than the control group (&lt;i&lt;P&lt;/i&lt;&lt;0.05); contrast treatment, efficacy of study group was significantly better than the control group (&lt;i&lt;P&lt;/i&lt;&lt;0.05). Conclusion: The application of CT spectroscopy in the diagnosis of liver micrometastases is helpful for early detection and early treatment, and has higher diagnostic value. It is beneficial for patients to improve liver function, and is worthy of clinical application.
