多层螺旋CT与冠状动脉造影在心肌桥-壁冠状动脉成像诊断中的对比研究

Comparative research with MSCT and CAG in the myocardial bridge-wall diagnostic coronary angiography

目的:对比分析多层螺旋CT(MSCT)与冠状动脉造影(CAG)在心肌桥-壁冠状动脉成像诊断中应用价值。方法:选取经确诊的心肌桥-壁冠状动脉(MB-MCA)患者93例,对其进行导管CAG和MSCT扫描,比较两种检查手段的诊断准确性,并对其结果进行相关性分析。结果:MSCT和CAG两种检查手段在诊断表浅型和深埋型MB-MCA中具有高度的一致性,在诊断MBMCA平均长度、平均深度上比较具有统计学意义(t=3.021,t=3.758;P<0.05),狭窄检出率比较无差异。结论:MSCT作为一种新型、无创的MB-MCA检查手段,其诊断结果可靠、准确,能够为临床医生提供更加丰富的诊断信息,可广泛应用于MB-MCA临床诊断中。

Objective： To comparative Research with MSCT and CAG in the myocardial bridgewall diagnostic coronary. Methods： Selected 93 patients for the study in January 2011 to the end of December 2013,MB-MCA patients diagnosed in Beijing North Hospital, all patients underwent catheter coronary angiography（CAG） and 64-slice spiral CT（MSCT）, comparison of the diagnostic accuracy of the two inspection methods, and the results of the correlation analysis, results processing and analysis using statistical software SPSS17.0. Results： MSCT and CAG were two examination methods in the diagnosis of superficial and deep type MB-MCA, witha high degree of consistency in the diagnosis of MB-MCA average length, average depth comparison with statistical significance（t=3.021, t=3.758; P〈0.05）, there was not statistically significant comparison in the narrow detection rate. Conclusion： MSCT as a novel, non-invasive means of MB-MCA examination, the diagnosis results are reliable, accurate and capable of providing a richer diagnostic information for clinicians, clinician and patient can be widely applied.
