摘要
目的，比较多层螺旋CT双期增强扫描（MDCT），数字减影血管造影（DSA），碘化油CT（CT）扫描对肝内富血管肝细胞癌结节的诊断价值。方法 80例肝癌患者均行MDCT，DSA，碘化油CT检查，比较三种影像学方法对结节型原发性肝癌的检出率。结果 对〉2cm的肝癌结节，三种方法检出率无明显差异（P〉0.05），对1-2cm的肝癌结节，三种方法检出率的差异无统计学意义（P〉0.05），对于〈cm的肝癌结节，MDCT检出47个结节（94.0%），碘化油CT检出27个结节（54.0%），两者检出率差异有统计学意义（χ2=3.11,P〈0.01）,DSA只检出16个（32.0%）〈1cm的结节，与MDCT和碘化油CT扫描相比，差异均有统计学意义（χ2=9.09,9.03,均P〈0.01）,结论 MDCT能够较好显示肝癌供血动脉情况，可作为治疗前综合评价的有效影像学检查方法。
Objective To compare the value of biphasicmulti-detector row helical computed tomogrpahy （MDCT）,digital subtraction angioraphy（DSA） and lipiodol computed tomography（CT） in hypervascular hepatocellular careinoma（HCC）.Methods 80 cases with liver cancer were underwent MDCT,DSA,iodized oil CT sean,then compared detection rated of three methods.Results In detecting hepatic nodules（〉2cm）,these three imaging techniques had the same sensitivity;for 1-2cm hepatic nodules,the detecting rate had no significant difference;The MDCT scan〈1cm detected 47 nodules（94.0%）,iodized oil CT detected 27nodules（54.0）,both statistically significant difference in detection rate（χ2=3.11,P〈0.01）,DSA is only detected 16 nodules（32.0%） compared with enhanced dual-phase MDCT scan and iodized oil CT detection rate the differences were statistically significant（χ2=9.09,9.03,all P〈0.01）.Conclusion MDCT is able to better show feeding arteries of hepatocellular carcinoma.The imaging examination of liver cancer before treatment can be used as a comprehensive evaluation.
