Brief Summary
This study is aimed to assess the value of three-dimensional time-of-flight magnetic resonance angiography (3D-TOF-MRA) in hemodialysis patients with occlusive disease in arteriovenous fistula (AVF). ...
Detailed Description
The Principle of 3D-TOF-MRA is based on the "flow effect" of MR. In the GE sequence of MRA imaging, the effect of RF pulses makes the protons in the stationary tissue in the active layer in a saturate...
