A novel MR angiography (MRA) method, swap phase encode mended data (SPEED), was developed. Two one-shot images with the phase-encode directions swapped were collected within a single breathhold 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.
