WebHistorically, IR techniques were widely used in the "early days" of MRI (c. 1980-1985). They produced excellent image contrast, especially for T1-weighted imaging, but were time-consuming (15-20 minute sequences typical). After about 1985 spin-echo techniques largely supplanted IR for most applications. In the late 1990's use of the fast spin ... Web2 days ago · April 13, 2024 — 05:28 am EDT.
