The ferumoxytol-enhanced 4D MR angiography with MUSIC (Multiphase Steady State Imaging with Contrast) technique provides a single data set that captures dynamic cardiovascular anatomy and ventricular function at the same time. Homogeneous opacification of all cardiovascular structures within the imaging volume allows full sequential segmental approach to the congenital heart diseases without any blind spots. The complex systemic and pulmonary venous anatomy is particularly well captured in the MUSIC. Cinematographic display of multiplanar sectional and 3D volume images is helpful in the morphological identification of the cardiac chambers, the assessment of the dynamic nature of the ventricular outflow tracts, and the assessment of the coronary arterial origins and courses.
采用MUSIC(多期稳态对比成像)技术的铁羧麦芽糖增强4D磁共振血管造影可提供一个数据集,能同时捕捉动态心血管解剖结构和心室功能。成像容积内所有心血管结构的均匀显影,使得在先天性心脏病的诊断中能够采用完整的序列节段分析方法,不存在任何盲点。MUSIC技术能特别清晰地显示复杂的体静脉和肺静脉解剖结构。多平面断层图像和三维容积图像的电影式显示,有助于对心腔进行形态学识别、评估心室流出道的动态特性以及评估冠状动脉的起源和走行。
