Abstract: A preparatory pulse sequence is applied prior to an imaging pulse sequence during a diffusion-weighted MRI scan. The preparatory pulse sequence diffusion weights the longitudinal magnetization using a gradient waveform that is first moment nulled to reduce image artifacts caused by patient motion.

Abstract: Methods and systems for generating T1-weighted images are provided. The method includes acquiring a pair of single-shot fast-spin-echo (SSFSE) images S1 and S2. The method further includes generating a T1-weighted image ST1w based on S1 and S2.

Abstract: A technique is set forth that is designed to reduce RF induced power in high field MR imaging that includes application of an initial contrast preserving phase of RF pulses. These initial RF pulses are designed to have a constant, relatively high flip angle over the initial contrast preserving phase. Following an effective TE, a ramp down phase is applied that has a limited number of RF pulses with a flip angle that is less than the flip angle of those in the initial contrast preserving phase. Further, the RF pulses in the ramp down phase have a flip angle that is decreased over the ramp down phase. This technique provides improved resolution and steady contrast and SNR, while significantly reducing induced RF power.

Abstract: An automatic field of view optimization method for maximizing resolution and eliminating aliasing artifact includes the steps of measuring for an optimal field of view, acquiring images using this optimized field of view, and reconstructing images in a field of view consistent data set.
