| 摘要 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。 |

| ABSTRACT Objective: To analyze and compare the detection rate of CT and MR in cirrhosis of the liver under the background of small liver cancer, and to explore their diagnosis value. Methods: 91 confirmed patients with cirrhosis in the context of small liver cancer from our hospital during June 2010 to June 2015 were selected as the objects, from which 102 lesions were diagnosed by pathology and clinical,including 69 cases of small liver cancer and 33 cases of micro hepatocellular carcinoma. All patients were examined at different times or sequence by spiral CT and MRI, and their detection rate of liver cancer were compared. Results: Using the row helical CT, 91 cases of lesions were found, including 66 cases of small liver cancer and 25 cases of micro liver cancer; And by MRI method, 95 lesions were examined, including 67 cases of small liver cancer and 28 cases of micro liver cancer. To the 69 lesions of small liver cancer, the highest detection rate were gotten at the arterial phase of CT(92.75%)and LAVA(92.75%), and the lowest one was by CT plain scanning (76.81%); To the 33 lesions of micro liver cancer, the highest detection rate was gotten at the arterial phase of LAVA (75.76%), and the lowest one was at the equilibrium phase of LAVA (36.36%). The detection rates to small liver cancer were significantly higher than that of the micro liver cancer by CT plain scanning, portal venous PHASE, arterial PHASE, equilibrium PHASE and MRI - IN - PHASE, LAVA balance period and LAVA plain scanning (P<0.05); The detection rate of CT to small liver cancer was significantly higher than that to micro liver cancer (P<0.05). There were no significant difference between the detection rates of magnetic resonance imaging (MRI) to small and micro liver cancer (P>0.05). The detection rates of small liver cancer were not significantly different between by MRI and by CT (P>0.05), but the rate of MRI to micro liver cancer was obviously higher than that of CT (P<0.05). Conclusion: The detection rates to examine the small and micro liver cancer lesions were the highest at the sequence of MRI - LAVA arterial phase. There were no signifi- cant difference between CT and MRI to small liver cancer, but the detection rate of MRI had more obvious advantage. |
