3D Phase Sensitive B1 Mapping

چکیده
INTRODUCTION: Sodium MRI shows promise in assessing cartilage health [1], characterizing tumors [2], detecting abnormal sodium levels in the kidneys [3], and assessing tissue damage following stroke [4]. However, relatively low Na concentrations in biological tissues, a rapid biexponential signal decay, and a low gyromagnetic ratio make sodium MRI challenging. Recent improvements in MRI hardware, high field scanners, and the development of more efficient pulse sequences have enabled higher quality sodium MRI in vivo in reasonable scan times [5].

Turbo Spin Echo Bloch Siegert Shift B1 Mapping
An interesting method for B1 mapping based on the Bloch-Siegert (BLS) shift was recently presented (1,2) for gradient echo (FLASH) and Spin Echo (SE) sequences. This method uses off-resonant pulses before signal acquisition to encode the B1 information into the signal phase. Fast B1 mapping is possible since the repetition time has only minor influence on the quality of the phase information. I...
متن کاملB1-insensitive T2 mapping of healthy thigh muscles using a T2-prepared 3D TSE sequence
PURPOSE To propose a T2-prepared 3D turbo spin echo (T2prep 3D TSE) sequence for B1-insensitive skeletal muscle T2 mapping and compare its performance with 2D and 3D multi-echo spin echo (MESE) for T2 mapping in thigh muscles of healthy subjects. METHODS The performance of 2D MESE, 3D MESE and the proposed T2prep 3D TSE in the presence of transmit B1 and B0 inhomogeneities was first simulated...
متن کاملFast phase-modulated B1+ mapping in the low flip-angle regime
Introduction and purpose: In high-field MRI phased transmit arrays are used to mitigate RF issues, e.g. optimizing the inhomogeneous B1 field using spatially tailored RF pulses played out by such an array. In order to design the RF pulses that produce the desired excitation field, the B1 field per coil must be mapped. Ideally, these B1 mapping techniques are fast and have a low SAR deposition. ...
متن کاملCharacterization of Phase-Based Methods Used for Transmission Field Uniformity Mapping: A Magnetic Resonance Study at 3.0 T and 7.0 T
Knowledge of the transmission field (B1(+)) of radio-frequency coils is crucial for high field (B0 = 3.0 T) and ultrahigh field (B0 ≥7.0 T) magnetic resonance applications to overcome constraints dictated by electrodynamics in the short wavelength regime with the ultimate goal to improve the image quality. For this purpose B1(+) mapping methods are used, which are commonly magnitude-based. In ...
متن کاملSA2RAGE: a new sequence for fast B1+ -mapping.
At high magnetic field strengths (≥ 3T), the radiofrequency wavelength used in MRI is of the same order of magnitude of (or smaller than) the typical sample size, making transmit magnetic field (B1+) inhomogeneities more prominent. Methods such as radiofrequency-shimming and transmit SENSE have been proposed to mitigate these undesirable effects. A prerequisite for such approaches is an accurat...
متن کاملAn experimental comparison of B1-mapping Techniques at two field strengths
Introduction: During the last years, a high interest in mapping of the B1-field has led to the development of a large number of techniques. Sequences designed for 2D and 3D acquisitions, based on amplitude or phase information have been presented. For an experimental comparison of these techniques, six different sequences were implemented on animal scanners with field strengths of 7 T and 16.4 ...
