title: [Comparison of two coils for MR angiography based on the SDNR method].
abstract: In this paper, signal-to-noise ratio (SNR) and signal different-to-noise ratio (SDNR) methods were used to compare image quality using two different radiofrequency coils. The two coil types included an eight-element phased-array coil and a quadrature birdcage head coil with endcap and the comparison studies performed on a uniform cylindrical phantom and volunteer respectively. The results showed phased-array coil have advantages and proved effectiveness of the method in the evaluation and selection of coils.
