Abstract: A system for performing a real-time frequency adjustment during medical imaging includes at least one memory and at least one processor. The at least one memory is configured to store instructions and the at least one processor is configured to execute the instructions to cause the system to apply a navigator before a repetition time (“TR”) variant spatial-encoding event of a first TR of a plurality of TRs, determine phase change information from a navigator signal acquired after the navigator is applied, and adjust a radio frequency (“RF”) pulse frequency of the medical imaging based on the phase change information.

Abstract: Methods, systems and computer-readable storage mediums relate to imaging techniques of a region, for example, the brain, with magnetization transfer contrast (MTC°) effects with less specific absorption rate (SAR). The methods, systems and computer-readable storage mediums may include acquiring MR image data from at least one magnetic resonance (MR) scan that includes a pre-pulse signal and a pulse sequence. The pre-pulse signal may be less than 500°, e.g., from about 150° to 425°, and the pulse-sequence may be a gradient echo based sequence. The methods, systems and computer-readable storage mediums may include generating information associated with an image of at least one region of a subject. The information may include quantitative or qualitative information of a region of a brain. The quantitative information may include volume information, contrast to noise ratio information, number of voxels, as well as other information.
