High-resolution full pancreas water T1 mapping
Motivation: T1 mapping provides valuable insights for the assessment of pancreatic diseases which might be challenging to evaluate if only based on qualitative MRI. Goal(s): Not only a high-resolution, fast T1 mapping method of the entire pancreas remains a challenge, but also a technique for water T1 mapping since the T1 is biased in the presence of fat. Approach: This work proposes a high-resolution, rapid, continuous inversion-recovery Look-Locker method combining a spiral read out with Dixon and a dictionary-based processing for water T1 mapping. Results: The entire pancreas is scanned within 24 slices, distributed in 3 breath-holds of 12s each. Impact: The present work proposes a high-resolution water T1 mapping methodology of the whole pancreas: 24 slices (2x2x5mm3) in 3 short breath-holds of 12s. The proposed method aims to support the fast assessment of diseases in the entire pancreas.
