متن کاملOptimization of inversion time for postmortem short-tau inversion recovery (STIR) MR imaging.
PURPOSE Signal intensity and image contrast differ between postmortem magnetic resonance (PMMR) images and images acquired from the living body. We sought to achieve sufficient fat suppression with short-tau inversion recovery (STIR) PMMR imaging by optimizing inversion time (TI). MATERIAL AND METHODS We subjected 37 deceased adult patients to PMMR imaging at 1.5 tesla 8 to 60 hours after con...

Figure 2. Renal angiograms with the same zoom. (b) MIP of MIR 3D ATR-bSSFP (1:08 min) demonstrates excellent background suppression compared to (a) the same sequence without MIR or gating (24 s). Superb suppression enabled rapid projective scans. (c) MIR 2D ATR-bSSFP (2 shots/3 heartbeats) achieved higher vessel SNR and sharpness than SSFSE. (d) MIR 2D SSFSE (1 shot/1 heartbeat) realized near-p...
متن کاملEvaluation of Non-Contrast Time-Spatial Labeling Inversion Pulse for Abdominal Angiography Compared to Contrast- Enhanced Angiography
Purpose In light of recent findings linking gadolinium based contrast media to the onset of Nephrogenic Systemic Fibrosis (NSF), it has become increasingly important to use non-contrast MR Angiography techniques to evaluate and diagnose renal artery stenosis and arterial disease. Time-Spatial Labeling Inversion Pulse (Time-SLIP) [1-3] is a non-contrast technique that has the ability to provide ...
متن کاملAccelerated Time-SLIP Cerebral MR Angiography by Use of Dual Inversion Pulse for Background Suppression
Introduction Time-Spatial Labeling Inversion Pulse (time-SLIP) which is a technique of magnetic resonance angiography (MRA) based on arterial spin labeling (ASL) are utilized in various situations [1]. However, to visualize cerebral angiograms, the background signal cannot suppress enough in the conventional time-SLIP technique because of longer T1 and T2 value of cerebrospinal fluid (CSF). The...
