| 摘要 目的：对比分析MRI和螺旋CT增强在肝脏占位性病变诊断中的价值。方法：以2012年7月-2016年5月我院收治的临床考虑为肝脏占位性病变70例患者为研究对象，将70例患者根据入组先后顺序分为两组，35例行增强CT扫描，35例行动态增强MRI扫描，比较两组患者的病理诊断结果、病灶个数及直径、增强CT及MRI的诊断结果和检查过程中的不良反应及耐受性。结果：CT增强组和MRI增强组的肝脏占位性病变的病理诊断、病变类型、分布及病灶个数(71 vs 70)、病灶直径(2.25±2.01 cm vs 2.19±1.98 cm)比较差异均无统计学意义(P>0.05)；以病理诊断结果为金标准，MRI增强组的总诊断符合率为85.71%，CT增强组的总诊断符合率为77.14%，MRI增强组的总诊断符合率高于CT增强组，但差异无统计学意义(P>0.05)；CT增强组共发生2例不良反应，均为轻度恶心，MRI增强组未出现造影剂不良反应，CT增强组的不良反应发生率(5.71% vs 0.00%)及视觉模拟评分法(VAS)评分(1.25 0.96分 vs 0.71 0.56分)均显著高于MRI增强组(P<0.05)。结论：CT增强和MRI增强扫描对于肝脏占位性病变的诊断均具有较高的临床价值，其中MRI增强扫描的安全性和耐受性更高，临床医师可根据患者的经济状态、身体状态等因素的综合评估，选择合适的检查手段，必要时可两者联合检查，以提高诊断的准确性。 |

| ABSTRACT Objective: To investigate the diagnostic value of MRI and CT for the liver space-occupying lesions. Methods: The clinical data of 70 cases of patients with liver space-occupying lesions in our hospital from June 2012 to May 2016 were divided into two groups and retrospectively analyzed. 35 cases underwent contrast enhanced ct scans(CT group), and others underwent dynamic con- trast-enhanced MR imaging(MRI group). The pathological diagnosis, number of lesions and lesions diameter were ompared between two groups. Results: No significant difference was found in the pathological diagnosis, number of lesions(71 vs 70) and lesions diameter(2.25 ±2.01cm vs 2.19±1.98 cm) between two groups(P>0.05). As the gold standard by pathological diagnosis results, correct diagnostic rate of MRI group were 85.71%, which was 77.14% CT group and lower than that of the MRI group, but no significant difference was found between two groups(P>0.05). The incidence of adverse reactions in CT group was significantly higher than that of the MRI group(P>0.05). Conclusion: Both CT and MRI enhancement scanning have higher diagnostic value for the liver space-occupying lesions, but MRI enhancement scanning has higher safety and tolerability. |
