Three-Dimensional MRCP with Reduced RF Power Deposition

John P. Mugler, III¹, Wilhelm Horger², Berthold Kiefer²

This work explored two approaches for reducing the RF power deposition of MRCP imaging based on a turbo-spin-echo pulse sequence. An adiabatic T2 preparation applied just before the excitation RF pulse, or a very long first echo spacing, combined with partial-Fourier acquisition permitted power deposition to be reduced by 25%-40% compared to that for a standard MRCP pulse sequence, while providing image quality comparable to that for the standard method. These methods will be valuable for addressing power-deposition limitations of MRCP at 3T, and will permit more consistent MRCP image quality to be achieved.
