Abstract：Objective: To image the arteries and veins of the abdomen and lower extremities in the crucial patients, using bolus tracking 3D CE-MRA technology. Material and Methods: With Philips gyroscan intera 1.5T superconducting MR machine, body coil and special leg rest, using bolustrack and mobitrack(intelligent tracking skill) scan technology, 4 crucial patients suspected of vascular disease, who can’t cooperate with doctors, were scanned. Results: All the 4 patients were able to accomplish the examination and the images of the vessels from the abdomen to lower extremities were of high quality with satisfied results. Conclusion: Suitable posture chosen, corresponding parameters well-modified and bolus-tracking 3D CE-MRA technology adopted, we can obtain high-quality images of vessels, even for the severely sick patients and thus we can provide necessary information in time before operation and therapy.
