B1-insensitive T2 preparation for improved coronary magnetic resonance angiography at 3 T.
At 3 T, the effective wavelength of the RF field is comparable to the dimension of the human body, resulting in B1 standing wave effects and extra variations in phase. This effect is accompanied by an increase in B0 field inhomogeneity compared to 1.5 T. This combination results in nonuniform magnetization preparation by the composite MLEV weighted T2 preparation (T2 Prep) sequence used for cor...
متن کاملA Cylindrical, Inner Volume Selecting 2D-T2-Prep Improves GRAPPA-Accelerated Image Quality in MRA of the Right Coronary Artery
BACKGROUND Two-dimensional (2D) spatially selective radiofrequency (RF) pulses may be used to excite restricted volumes. By incorporating a "pencil beam" 2D pulse into a T2-Prep, one may create a "2D-T2-Prep" that combines T2-weighting with an intrinsic outer volume suppression. This may particularly benefit parallel imaging techniques, where artefacts typically originate from residual foldover...
متن کاملImproved image quality in GRAPPA-accelerated coronary MRA using an outer volume suppressing 2D-T2-Prep
Background Two-dimensional (2D) spatially selective radiofrequency (RF) pulses may be used to excite a restricted volume of tissue. By incorporating a “pencil beam” 2D pulse into a T2-Prep module, one may create a “2D-T2-Prep” that combines T2-weighting with outer volume suppression. This may be of particular benefit to parallel imaging techniques, where artefacts typically originate from resid...
متن کاملImproved fat signal suppression for coronary MRA at 3T using a water-selective adiabatic T2-Prep technique
Background In MRI, fat signal suppression is mandatory for unambiguous visualization of cardiac anatomy but remains challenging at high field. Fat saturation usually directly precedes the imaging portion of a cardiac MRI sequence. It is often used in conjunction with other magnetization preparation modules, such as T2 Preparation (or T2-Prep), to improve blood/myocardium contrast. We propose a ...
