摘要
目的 通过对比超声检查,分析非对比增强全心冠状动脉磁共振血管成像(NCE-CMRA)技术评估冠状动脉方面的优势,探讨该技术诊断儿童川崎病冠状动脉病变的价值.资料与方法 回顾性分析 2017 年 6 月—2021 年 6 月兰州大学第二医院经临床确诊的41例川崎病患儿的NCE-CMRA及超声资料.对比超声与NCE-CMRA对冠状动脉的显示能力,分析NCE-CMRA技术的成像特点,总结NCE-CMRA显示的冠状动脉病变范围、程度等影像学特征.结果 41 例患儿NCE-CMRA检查整体血管节段显示率为75.6%;超声整体节段显示率为46.3%,两种技术差异有统计学意义(χ2=59.04,P<0.001).针对冠状动脉中、远段的显示,NCE-CMRA较超声具有明确的显像优势(χ2=57.98、161.47,P<0.001).41例患儿中,25例(200节段)冠状动脉受损,94个节段表现为不同程度扩张,其中巨大冠状动脉瘤8段(8.6%),中型冠状动脉瘤35段(37.2%),小型冠状动脉瘤或冠状动脉扩张51段(54.2%).结论 NCE-CMRA技术能够客观、清晰地显示儿童冠状动脉,准确反映川崎病所致冠状动脉受损程度,在诊断和评估儿童川崎病冠状动脉病变方面具有重要临床意义.
Abstract
Purpose To demonstrate the advantages of non-contrast-enhanced whole-heart coronary magnetic resonance angiography(NCE-CMRA)in evaluating coronary arteries by comparing ultrasonography(US),and to explore the clinical value of NCE-CMRA in the diagnosis of coronary artery lesions of Kawasaki disease(KD)in children.Materials and Methods NCE-CMRA and US imaging data of 41 children with KD from June 2017 to June 2021 who were diagnosed clinically in Lanzhou University Second Hospital were analyzed retrospectively.The display ability of US and NCE-CMRA in coronary arteries were compared.At the same time,the imaging characteristics of NCE-CMRA were analyzed,and the imaging characteristics such as the range and degree of coronary artery lesions displayed by NCE-CMRA were summarized.Results The overall segment display rate of NCE-CMRA in 41 children with KD was 75.6%;the overall segment display rate of US was 46.3%,with statistical difference between the two techniques(χ2=59.04,P<0.001).Regarding the display of the middle and distal segments of coronary arteries,NCE-CMRA had a clear imaging advantage over US(χ2=57.98 and 161.47,P<0.001).In all cases,25 patients(200 segments)had coronary artery lesions,and 94 segments of coronary artery showed different degrees of dilatation,including 8 segments(8.6%)of giant coronary artery aneurysm,35 segments(37.2%)of medium coronary artery aneurysm,and 51 segments(54.2%)of small coronary artery aneurysm or coronary artery dilation.Conclusion NCE-CMRA technology can objectively and accurately display coronary artery in children,and it can specifically evaluate the degree of damage caused by KD.It has important clinical significance in the diagnosis and evaluation of coronary artery lesions in children with KD.
