BOLD fMRI using a modified HASTE sequence
For more than a decade, turbo spin echo (TSE) pulse sequences have been suggested as an alternative to echo planar imaging (EPI) sequences for fMRI studies. Recent development in parallel imaging has renewed the interest in developing more robust TSE sequences for fMRI. In this study, a modified half Fourier acquisition single-shot TSE (mHASTE) sequence has been developed with a three-fold GRAP...
متن کاملT2-Weighted Liver MRI Using the MultiVane Technique at 3T: Comparison with Conventional T2-Weighted MRI
OBJECTIVE To assess the value of applying MultiVane to liver T2-weighted imaging (T2WI) compared with conventional T2WIs with emphasis on detection of focal liver lesions. MATERIALS AND METHODS Seventy-eight patients (43 men and 35 women) with 86 hepatic lesions and 20 pancreatico-biliary diseases underwent MRI including T2WIs acquired using breath-hold (BH), respiratory-triggered (RT), and M...
متن کاملHASTE diffusion-weighted MRI for the reliable detection of cholesteatoma.
PURPOSE To assess the detection efficiency of Half-Fourier acquisition single-shot turbo spin-echo (HASTE) diffusion-weighted magnetic resonance imaging (MRI) for cholesteatoma. MATERIALS AND METHODS A total of 21 patients with suspected primary (n=16) or recurrent cholesteatoma (n=5) underwent MRI in a 1.5 Tesla scanner using an adapted protocol for cholesteatoma detection that included a co...
متن کاملHASTE sequences for functional MRI: BOLD and VASO
B. A. Poser, D. G. Norris FC Donders Centre for Cognitive Neuroimaging, Nijmegen, Netherlands Introduction Multiply-refocused sequences such as HASTE are attractive for functional MRI (fMRI) as they are free of susceptibility artifacts, and yield pure T2 contrast. The latter can be advantageous for two fMRI applications: First, spin echo (SE) based fMRI. SE reportedly offers better spatial loca...
