## Abstract As recently demonstrated, spin saturation effects in 3D time‐of‐flight (TOF) MR angiography (MRA) can be reduced by using RF pulses with linearly increasing flip angles (ramp pulses) in the main direction of flow. We developed a model for calculating the signal distribution of proton fl

## Abstract ## Purpose To evaluate the image quality of high‐spatial‐resolution three‐dimensional magnetic resonance cholangiography (MRC) with a high‐sampling‐efficiency technique (sampling perfection with application optimized contrasts using different flip angle evolutions [SPACE]) in compariso
