使用MR进行血管成像的当前基于血流的序列的性能在固有血流缓慢的区域中受到严重限制。我们用与流动无关的成像方法来解决这个问题。具体而言，我们使用具有长回波时间的流量补偿、水选择性、短TI反转恢复序列生成肢体中血液的投影图像，同时抑制来自所有其他组织（主要是骨骼肌、骨髓和皮下脂肪）的信号。我们通过实验评估了这种序列的有效性，并提出了体内结果，清楚地表明了该方法的潜力。出版社：Academic Press，Inc.
The performance of current, flow‐based sequences for imaging vasculature using MR is severely restricted in regions with inherently slow flow. We address this problem with a flow‐independent imaging method. Specifically, we generate projection images of blood in the limbs while suppressing signal from all other tissues (primarily skeletal muscle, bone marrow, and subcutaneous fat) using a flow‐compensated, water‐selective, short TI inversion recovery sequence with a long echo time. We experimentally evaluate the effectiveness of this sequence and presentin vivoresults clearly demonstrating the method's potential. © 1991 Academic Press, Inc.
