摘　　要：目的观察动态核磁共振成像(MRI)和螺旋CT增强在肝脏占位性病变诊断中的价值,对两种诊断方法的病理结果、不良反应发生情况进行比较。方法 72例疑似肝脏占位性病变患者,按照随机法分为对照组和观察组,每组36例。对照组使用螺旋CT增强进行检查,观察组采用动态MRI进行检查,比较两组的诊断符合率以及患者不良反应发生情况(恶心呕吐等)、视觉模拟评分法(VAS)评分。计算两组真阳性率、假阳性率、真阴性率、假阴性率,以病理为金标准,以灵敏度和特异度绘制受试者工作特征(ROC)曲线。结果以病理诊断作为金标准,观察组诊断符合率为96.97%(32/33),略高于对照组的93.75%(30/32),但差异无统计学意义(P>0.05)。观察组不良反应发生发生率0、VAS评分(0.56±0.17)分低于对照组的11.11%、(1.10±0.31)分,差异均具有统计学意义(P<0.05)。对照组真阳性率和假阳性率分别为93.75%和0,真阴性率和假阴性率分别100.00%和6.25%;观察组的真阳性率和假阳性率分别为96.97%和0,真阴性率和假阴性率分别100.00%和3.03%。对照组灵敏度和特异度分别为93.75%、100.00%,观察组的灵敏度和特异度分别为96.97%、100.00%。结论螺旋CT增强和动态MRI检测在肝脏占位性病变的诊断中均有较高的应用价值,将两种方法与病理诊断相比,两种方法的诊断符合率均较高。但采用动态MRI检测的患者不良反应发生率较低,且检测准确度更高,在实际工作中可根据情况选择最适合的检测方案,必要时可采用联合诊断的方式以增加诊断的准确性。Objective To observe the value of dynamic magnetic resonance imaging(MRI)and contrast-enhanced spiral CT in the diagnosis of hepatic space-occupying lesions,and compared the pathological results and occurrence of adverse reactions of the two diagnostic methods.Methods A total of 72 patients with suspected hepatic space-occupying lesions were divided into control group and observation group according to random numerical table,with 36 cases in each group.The control group was treated with contrast-enhanced spiral CT,and the observation group was treated with dynamic MRI.The diagnostic coincidence rate,occurrence of adverse reactions(nausea and vomiting),and the visual analogue scale(VAS)score of the two groups were compared.The true-positive rate,false-positive rate,true-negative rate,and false-negative rate of the two groups were calculated.Using pathology as the gold standard,and receiver operating characteristics(ROC)curves was drawn and analyzed with sensitivity and specificity.Results Taking pathological diagnosis as the gold standard,the diagnostic coincidence rate of the observation group was 96.97%(32/33),which was slightly higher than 93.75%(30/32)of the control group,but the difference was not statistically significant(P>0.05).The incidence of adverse reactions 0 and VAS score(0.56±0.17)points of the observation group were lower than 11.11%and(1.10±0.31)points of the control group,and the difference was statistically significant(P<0.05).In the control group,the true-positive rate and false-positive rate were 93.75%and 0,and the true-negative rate and false-negative rate were 100.00%and 6.25%respectively.In the observation group,the true-positive rate and false-positive rate were 96.97%and 0,and the true-negative rate and false-negative rate were 100.00%and 3.03%respectively.The sensitivity and specificity of the control group were 93.75%and 100.00%respectively,while those of the observation group were 96.97%and 100.00%respectively.Conclusion Contrast-enhanced spiral CT and dynamic MRI detection have hig
