[Diagnosis of lesions in the major abdominal blood vessels by three-dimensional dynamic contrast-enhanced magnetic resonance angiography].

Objective: To elucidate the working principles of three-dimensional dynamic contrast-enhanced magnetic resonance angiography(3D DCE-MRA)and assess its value in the diagnosis of lesions in the major abdominal blood vessels.

Methods: The imaging data of 3D DCE-MRA and conventional MR examination in 32 cases of suspected major abdominal blood vessel diseases were obtained and analyzed retrospectively.

Results: The peak flow of contrast agents through the abdominal aorta at the level of renal artery occurred 17 to 23 s after the injections.
