Fast multi-contrast brain exams are highly desirable in clinical practice. Spiral sampling has high efficiency in terms of spatial encoding. Thus it holds great potential for many MRI applications. In this work, we optimized a fast multi-contrast brain imaging protocol based on multi-shot spiral acquisitions. Six contrasts (T1W-FLAIR, T2W, PDW, T2*W, T2W-FLAIR, DWI) and apparent diffusion coefficient (ADC) maps with an in-plane resolution of 1.0 mm2 for a full brain MR exam can be obtained in about 2 minutes.
