摘要:
目的 利用一次呼吸抑制快速磁共振电影建立健康国人右心室容积、射血分数正常值。方法 健康自愿者57(男37,女20)例,平均年龄33(18~58)岁。用FLASH序列轴位定位,用心电门控呼吸抑制FLASH2D电影序列做双斜位和四腔磁共振电影,用西门子心脏功能分析软件包进行各数据测量分析。结果 右心室舒张末期容积指数77±13 ml/m2,右心室收缩末期容积指数31±6 ml/m2,射血分数(61±6)%。结论 一次呼吸抑制快速磁共振电影能准确测量右心室体积及射血分数,在评价心脏病患者时应做为常规检查。
Abstract:
AIM To establish right ventricular(RV) volume and ejection fraction(EF) in normal volunteers with fast magnetic resonance (MR) imaging a breath-hold technique.METHODS Fifty-seven health adult volunteers(20 female, 37 male; mean age:33 years; range:18 ~ 59 years). Turbo fast low-angle shot(FLASH) was used to localize the intrinsic heart planes. Double-angulated view and four-chamber view were acquired with a segmental ECG-gated FLASH 2D cine sequence. All statistical analyses were performed with the Siemens software package.RESULTS Right ventricular endystolic volume index 77±13 ml/m2. Right ventricular endystolic volume index 31±6 ml/m2. Right ventricular ejection fraction (61±6)%. CONCLUSION RV volumes and EF can be routinely assessed with fast MRI in cardiac patients. Our established normal values allow the assessment of RV( and LV) global systolic function at rest with a high certainty for normal subjects.
