WebA conventional spin echo diffusion weighted sequence consists of two monopolar symmetric gradient lobes occurring before and after the 180° refocusing RF pulse to provide M 0 nulling 1. The timing and amplitude of these diffusion encoding gradient lobes impacts the diffusion encoding sensitivity, known as the b-value. WebJan 1, 2024 · In brief, T2-weighted and T2*-weighted images were automatically registered to a common template image, which was generated in a previous study by averaging spinal cord MRIs from 50 adult subjects. 12,13 The T2-weighted image was used to precisely identify vertebral levels, and the T2*-weighted image was used to automatically measure …
