Quantitative imaging has been very useful in neuroscientific and clinical applications, including glioma, tumor diagnosis and prognosis, brain maturation, and Alzheimer's disease. EPI is a powerful tool for quantitative imaging owing to its extremely fast acquisition. This work aims to develop a distortion-free, blip-up/down acquisition (BUDA) 3D-EPI with controlled aliasing in parallel imaging (CAIPI) sampling and joint Hankel low-rank image reconstruction for fast and robust multi-contrast high-resolution whole-brain imaging. The developed technique could generate distortion-free high-resolution whole-brain T2*mapping and quantitative susceptibility mapping in 47s at 1.1×1.1×1 mm resolution.
