目的探讨增强核磁共振成像(MRI)在肝脏局灶性病变诊断中的应用价值。方法 60例肝脏局部病变患者均经B超或CT检查发现肝脏局限性病灶,且均行常规T2W及T1W平扫,在此基础上进行增强扫描,并对其结果进行分析。结果本组60例患者共检出136个病灶,增强MRI检出率为88.2%,平扫检出率为75.0%,两者比较差异具有统计学意义(P<0.05);增强MRI定性准确率为86.8%,平扫定性准确率为66.2%,两者比较差异具有统计学意义(P<0.05)。结论采用增强MRI对肝脏局灶病变患者进行诊断可有效提高检出率,并具有较高的准确性及安全性,且毒副作用少,有较高的应用价值,可在临床上推广应用。
Objective To investigate the value of enhanced magnetic resonance imaging (MRI) in the diagnosis of focal liver lesions. Methods Sixty patients with liver lesions were examined by B-mode ultrasonography or computed tomography (CT). All the lesions were examined by conventional T2W and T1W. The contrast-enhanced scan was performed and the results were analyzed. Results A total of 136 lesions were detected in 60 patients in this study. The detection rate of enhanced MRI was 88.2% and the average detection rate was 75.0%. The difference between the two groups was statistically significant (P <0.05) (86.8%). The qualitative and qualitative accuracy of the scan was 66.2%. There was a significant difference between the two (P <0.05). Conclusions The diagnosis of patients with focal hepatic lesions by enhanced MRI can effectively improve the detection rate, and has high accuracy and safety, less toxic and side effects, higher application value, and can be widely applied in clinic.
