目的:研究和分析螺旋CT和核磁共振对肝脏囊性占位的诊断作用。方法:收集肝脏囊性占位患者共60例,患者均进行螺旋CT和核磁共振检查,对其诊断结果进行分析。结果:螺旋CT和核磁共振检查对肝脏囊性占位病变的检出率无统计学差异,P>0.05;核磁共振检查对患者的炎症性病变的检出率显著高于螺旋CT,P<0.05。结论:对于肝脏囊性占位病变,螺旋CT和核磁共振两种检查方式均能够有效检出,核磁共振对炎症性病变的敏感性更高。 Objective: To study and analyze the diagnostic value of spiral computed tomography and nuclear magnetic resonance in cystic masses of the liver. Methods: A total of 60 patients with cystic space occupying liver were collected. All patients underwent spiral CT and MRI examinations, and their diagnostic results were analyzed. Results: There was no significant difference in the detection rate of cystic mass lesions between spiral CT and MRI (P> 0.05). The detection rate of MRI in patients with inflammatory lesions was significantly higher than that of spiral CT (P <0.05) . Conclusion: For liver cystic lesions, both spiral CT and MRI can be detected effectively, and the sensitivity of nuclear magnetic resonance to inflammatory lesions is higher.
