目的利用碘对比剂进行肝脏CT多期增强扫描,探讨CT多期增强扫描在小肝癌诊断方面的价值。方法回顾2010年2月—2013年12月间确诊的95例小肝癌患者的病历资料,分析肝脏CT平扫及碘对比剂增强扫描的图像,评价增强扫描对小肝癌的诊断价值。结果 95位患者平扫时共发现121个病灶,采用碘对比剂多期增强扫描后共发现155个病灶,比平扫多发现34个病灶,占21.93%。在这多发现的34个病灶中,其中8例无明显不适及临床症状,CT平扫未见异常,只有化验室检验发现异常,占5.16%。结论碘对比剂肝脏CT多期增强扫描可以显著提高小肝癌的检出率,为临床科室制定治疗方案和评价预后提供了可靠依据,有较高的临床应用及推广价值。
Objective To evaluate the value of iodine contrast agent in multi-phase contrast-enhanced CT scan of liver in diagnosis of small hepatocellular carcinoma (HCC). Methods The clinical data of 95 patients with small hepatocellular carcinoma who were diagnosed from February 2010 to December 2013 were retrospectively analyzed. The images of hepatic CT scan and iodine contrast enhancement scan were analyzed to evaluate the diagnostic value of enhanced scan in small hepatocellular carcinoma. Results A total of 121 lesions were found in 95 patients during plain scan. A total of 155 lesions were found after multi-phase contrast-enhanced scan with iodine contrast agent, accounting for 21.93% of the total. Among the 34 lesions found in this series, 8 of them showed no obvious discomfort and clinical symptoms. CT scan had no abnormalities. Only laboratory tests showed abnormalities, accounting for 5.16%. Conclusions CT contrast enhanced liver CT scan can significantly improve the detection rate of small hepatocellular carcinoma and provide a reliable basis for clinical departments to develop treatment programs and evaluate the prognosis, which has high clinical application and promotion value.
