Small brain lesions such as multiple sclerosis (MS) are the most frequent inflammatory demyelinting disease of the central nervous system. T2-weighted imaging is a gold standard for diagnosing infratentorial brain lesions, while fluid-attenuated-inversion-recovery (FLAIR) imaging is known to be highly sensitive to lesions close to cerebro-spinal-fluid (CSF) but less sensitive in posterior fossa. Additionally, high-resolution three-dimensional (3D) imaging is preferred due to the small size of lesions. Given the facts above, the purpose of this work is to develop a novel phase-sensitive dual-acquisition single-slab 3D turbo/fast spin echo (SE) pulse sequence for acquiring both T2-weighted and CSF-suppressed images simultaneously in a single measurement.
