| 目的 探讨磁共振成像( MRI)对先天性大动脉转位(TGA)的诊断价值。方法 本组病例14例,男8例,女 6例,年龄2月~12岁,平均5.4±3.6岁。应用超导磁共振仪,选用心电图门控自旋回波技术(SE)、电影磁共振(cine-MRI)及磁共振造影(MRA)进行诊断,所有病例均做二维彩色多普勒超声心动图检查,10例同时做心血管造影(Angio)检查,2例经手术治疗。结果 MRI准确诊断本组病例包括完全性大动脉转位13例( 92.8 ％ ),纠正性大动脉转位 1例(7.2 ％ ) 。14例中,合并室间隔缺损12例( 85.6％ ),室间隔完整2例(14.4％),右室双出口 4例 (28.8％),心脏位置异常5例( 35.7 ％ ),肺动脉狭窄6例(43.2 ％) 。 14例中,10例经Angio或/和手术证实。结论 MRI对TGA的诊断具有重要临床价值,有利于外科手术方案的制定。 |

| Objective This study was to evaluate magnetic resonance imaging (MRI) in diagnosing congenital transposition of the great arteries (TGA). Methods 14 patients (male 8, female 6 ) aged 2 months to 12 years ( mean age 5.4±3.6 years ) were scanned with ECG-gated spin echo technique (SE), cine-MRI and magnetic resonance angiography (MRA) at superconductive magnetic system. All patients were examined with 2-dimensional color Doppler echocardiography and 10 of them had received angiography. 2 patients had surgical treatment. Results MRI could correctly depict the anatomic structure of TGA, including complete TGA (13 cases) and corrected TGA( 1 case). The associated defects included ventricular septal defects (12 cases), intact ventricular septal (2 cases ), double outlet of right ventricle (4 cases ), cardiac malposition (5cases ) and pulmonary stenosis (6cases ). The Results of MRI were comformed by Angio and /or surgery in 10 patients. Conclusion MRI is accurate in diagnosing congenital transposition of the great arteries . |
