[Three-dimensional MR angiography of the celiac artery with single breath holding]

We performed a three-dimensional MR angiography of the celiac artery with single breath holding. The measuring time was just twenty-three seconds. In four healthy volunteers, celiac arteries were visualized clearly, moved cephalad with expiration and caudad with inspiration. In two patients with the median arcuate ligament compression of the celiac artery, the degree of stenosis increased with deep expiration and decreased with deep inspiration. Using this technique, we obtained different vascular images with each respiratory phase. This technique is considered to be a useful three-dimensional MR angiography in the abdominal region without respiratory artifacts.
