提出了一种新的磁共振血管成像（MRA）方法--交换相位编码扩展数据（SPEED）法。在单个屏气期内收集相位编码方向交换的两个单次激发图像，并使用最大强度投影（MIP）进行处理以获得图像。在本研究中，使用半傅立叶（half-RARE）长回波序列弛豫增强（RARE）二维快速采集序列获得肺部MRA图像。使用SPEED技术获得的MIP图像对肺血管显示了良好的结果。
A novel MR angiography (MRA) method, swap phase encode extended data (SPEED), was developed. Two one‐shot images with the phase‐encode directions swapped were collected within a single breath‐hold period and processed with a maximum intensity projection (MIP) to obtain an image. In this study, a long echo train two‐dimensional rapid acquisition with relaxation enhancement (RARE) sequence with half‐Fourier (half‐RARE) was used to obtain the pulmonary MRA images. The MIP image obtained using the SPEED technique presented promising results for pulmonary vessels.
