背景：应用4D Flow磁共振成像技术对60例房颤患者和15例正常对照的左房(LA)和左心耳(LAA)血流动力学进行了研究。计算左房和左心耳的血流量和血流速度的解剖图，以量化心房峰值速度、平均速度和血流量
Background Atrial 4D flow magnetic resonance imaging was used for the characterization of left atrial (LA) and left atrial appendage (LAA) flow dynamics in patients with atrial fibrillation (AF).Methods and Results 4D flow magnetic resonance imaging measured in vivo 3D blood flow velocities in 60 AF patients and 15 controls. Anatomic maps of LA and LAA stasis and velocity were calculated to quantify atrial peak velocity, mean velocity, and stasis (velocities
