目的:分析比较CT与MR对肝硬化背景下小肝癌检出情况,探究CT与MR在肝硬化背景下小肝癌的诊断价值。方法:选择2010年6月~2015年6月期间,我院收治确诊为肝硬化背景下小肝癌患者91例为研究对象,病理及临床相关方法确诊102个病灶,其中小肝癌69个和微小肝癌33个,患者均在不同时期或序列下行多排螺旋CT与MRI检查,分析比较两者对小肝癌和微小肝癌的检出率。结果:多排螺旋CT检查发现肝癌小病灶91个,其中66个小肝癌,25个微小肝癌;MRI检查发现95个病灶,小肝癌67个,微小肝癌28个;69个小肝癌病灶,检出率最高的为CT动脉期(92.75%)与LAVA动脉期(92.75%),检出率最低的为CT平扫(76.81%);33个微小肝癌病灶,检出率最高为LAVA动脉期(75.76%),检出率最低的为LAVA平衡期(36.36%);CT平扫、门静脉期、动脉期、平衡期、MRI-IN-PHASE、LAVA平衡期、LAVA平扫对小肝癌的检出率显著高于对微小肝癌的检出率(P<0.05);CT对小肝癌的检出率显著高于微小肝癌的检出率(P<0.05),MRI对小肝癌与微小肝癌的检出率无显著差异(P>0.05);MRI与CT对小肝癌的检出率不存在差异(P>0.05),但MRI对微小肝癌的检出率显著高于CT(P<0.05)。结论:MRI-LAVA的动脉期序列对小肝癌病灶与微小肝癌病灶的检出率最高;CT与MRI在对小肝癌的检出率不存在差异,但MRI对微小肝癌的检出具有更明显的优势。
Objective: To compare the detection of small hepatocellular carcinoma in cirrhotic patients by CT and MR, and to explore the value of CT and MR in the diagnosis of small hepatocellular carcinoma in cirrhosis. Methods: From June 2010 to June 2015, 91 cases of small hepatocellular carcinoma diagnosed as cirrhosis in our hospital were selected as study objects. 102 lesions were confirmed by pathology and clinical related methods, of which 69 were small hepatocellular carcinoma and small hepatocellular carcinoma Thirty-three patients underwent multi-slice spiral CT and MRI in different periods or sequences, and analyzed the detection rate of both small and small hepatocellular carcinoma. Results: Multi-slice helical CT examination revealed 91 small lesions of liver cancer, including 66 small hepatocellular carcinoma and 25 small hepatocellular carcinoma. 95 lesions, 67 small hepatocellular carcinoma and 28 small hepatocellular carcinoma were detected by MRI; 69 small hepatocellular carcinoma lesions were detected The highest detection rate was CT arterial phase (92.75%) and LAVA arterial phase (92.75%), the lowest detection rate was CT scan (76.81%). The highest detection rate was in 33 LCC arteries (75.76% %). The lowest detection rate was LAVA balance (36.36%). The detection rate of small hepatocellular carcinoma on CT scan, portal vein phase, arterial phase, balance phase, MRI-IN-PHASE, LAVA balance phase and LAVA scan (P <0.05). The detection rate of CT on small hepatocellular carcinoma was significantly higher than that of small hepatocellular carcinoma (P <0.05). The detection rate of small hepatocellular carcinoma and small hepatocellular carcinoma on MRI (P> 0.05). There was no difference between MRI and CT in the detection rate of small hepatocellular carcinoma (P> 0.05). However, the detection rate of MRI for small hepatocellular carcinoma was significantly higher than that of CT (P <0.05). Conclusion: MRI-LAVA has the highest detection rate of small hepatocellular carcinoma and small hepatocellular carcinoma in the arterial phase sequence. There is no difference in the detection rate of small hepatocellular carcinoma between CT and MRI, but MRI has more obvious detection on small hepatocellular carcinoma Advantage.
