MRI Specific Absorption RateSAR how to calculate MRI SAR

Sequence modifications for RF-intensive pulse sequences such as diffusion-weighted imaging (DWI) become technically challenging at high-field magnets. These adjustments included decreasing slices per TR, decreasing flip angle, lengthening TR, increasing interecho spacing, and prolonging the RF pulse duration. However, these modifications led to reduced anatomic okcoin review coverage, alteration of tissue contrast, and diminished SNR. […]
