摘要：

Magnetic resonance angiography of the peripheral vascular system has been hampered by the limited view provided by available imaging coils. We have constructed an extended-length, split-saddle design radiofrequency (rf) coil for peripheral angiography. The two coil halves are inductively coupled, to each other and to the rf source. Details regarding the construction of the coil and comparison of the performance with the knee coil are described here. This coil provides the benefit of a larger field of view but with image quality comparable to that of a commercial knee coil.
