目的探讨CT灌注成像在肝癌早期诊断中的临床诊断价值。方法选择2015年1月至2016年6月期间在本院行手术治疗、病理诊断为肝癌早期的60例患者作为受试者;60例患者术前均行CT灌注成像检查,比较CT灌注成像与病理诊断结果,并总结其影像特征。结果 CT灌注成像确诊肝癌51例,与病理诊断完全相符者49例,符合率为81.67%。CT灌注成像显示病灶灌流量明显多于周围正常肝组织,具有明显高血流灌注特征,多数伴有肿瘤组织内局部低血流灌注。结论肝脏CT灌注成像对肝癌早期病变的检测准确性较高,有利于肝脏的早期确诊及治疗,临床应用价值较高。
Objective To investigate the clinical value of CT perfusion imaging in the early diagnosis of liver cancer. Methods Sixty patients with early diagnosis of HCC from January 2015 to June 2016 were enrolled in this study. 60 patients underwent CT perfusion imaging before operation and CT perfusion imaging Pathological diagnosis results, and summarize the image features. Results CT perfusion imaging confirmed 51 cases of liver cancer, which was completely consistent with the pathological diagnosis of 49 cases, the coincidence rate was 81.67%. CT perfusion imaging showed that the perfusion of the lesion was significantly more than that of the surrounding normal liver tissue, with obvious characteristics of high perfusion, most of which were accompanied with local hypoperfusion in the tumor tissue. Conclusion CT perfusion imaging of liver has high accuracy in early detection of liver cancer, which is good for the early diagnosis and treatment of liver, and has high clinical value.
