Abstract

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.
