Gradient recalled
WebGradient-echo techniques, including parallel imaging, were introduced to further reduce scanning time while producing equivalent or even improved image quality. Today, numerous sampling techniques in parallel imaging are available. WebNov 24, 2009 · Abstract Objective: Brain microbleeds on gradient-recalled echo (GRE) T2*-weighted MRI may be a useful biomarker for bleeding-prone small vessel diseases, with potential relevance for diagnosis, prognosis (especially for antithrombotic-related bleeding risk), and understanding mechanisms of symptoms, including cognitive impairment.

WebT 1 is extracted from a pair of spoiled gradient recalled echo (SPGR) images acquired at optimized flip angles. This T 1 information is combined with two refocused steady-state free precession (SSFP) images to determine T 2. T 1 and T 2 accuracy was evaluated against inversion recovery (IR) and spin-echo (SE) results, respectively. WebJul 1, 2008 · Depending on the signal sampled and used to form an image, steady-state sequences can be classified as (a) postexcitation refocused (only S+ is sampled), (b) preexcitation refocused (only S− is sampled), and (c) fully refocused (both S+ and S− are sampled) sequences.
