摘要
目的 对比64排MSCT、高场强MRI血管成像应用于急性主动脉综合征患者中的临床价值。方法 回顾性分析本院2017年3月至2019年7月收治的90例急性主动脉综合征患者的临床资料,观察MRI检查及MSCT检查的诊断结果进行讨论和分析;对比经MRI检查、MSCT检查对急性主动脉综合征的诊断准确性、敏感性和特异性及两种检查相关指标。结果 经MRI检查对急性主动脉综合征的诊断灵敏性、特异性和准确性分别为92.22%、81.11%、97.78%,MSCT检查对急性主动脉综合征的诊断灵敏性、特异性和准确性分别为88.87%、76.67%、95.56%,MRI检查对急性主动脉综合征的诊断灵敏性、特异性和准确性高于MSCT检查,但两者比较差异无统计学意义(P>0.05);MRI血管成像的图像质量评分高于MSCT血管成像,信噪比低于MSCT血管成像,差异具有统计学意义(P<0.05)。结论 MSCT、高场强MRI血管成像均可有效显示急性主动脉综合征的影像学特点,均可作为辅助诊断急性主动脉综合征的有效手段,临床可结合患者自身情况进行选择。
Objective To compare the clinical value of 64-row MSCT and high-field intensity MRI angiography in patients with acute aortic syndrome.Method The clinical data of 90 patients with acute aortic syndrome admitted to our hospital from March 2017 to July 2019 were retrospectively analyzed.The diagnosis results of MRI and MSCT were observed and analyzed.The diagnositic accuracy,sensitivity and specificity of MRI and MSCT for acute aortic syndrome and the related indicators were compared.Results The sensitivity,specificity and accuracy of MRI in the diagnosis of acute aortic syndrome were 92.22%,81.11%,and 97.78%,respectively.The sensitivity,specificity and accuracy of MSCT examination for acute aortic syndrome were 88.87.%,76.67%,95.56%,the sensitivity,specificity and accuracy of MRI examination for acute aortic syndrome were higher than those of MSCT,but the difference was not statistically significant(P>0.05).The image quality score of MRI angiography was higher than that of MSCT angiography,and the signal-to-noise ratio was lower than that of MSCT angiography.The difference was statistically significant(P<0.05).Conclusion MSCT and high field intensity MRI angiography can effectively display the imaging features of acute aortic syndrome,and can be used as an effective means to assist in diagnosing acute aortic syndrome.In clinic,it can be selected in combination with the patient's own situation.
