Whole pancreas water T₁ mapping at 3 Tesla.

ABSTRACT:

Purpose

A fast T₁ mapping method of the whole pancreas remains a challenge, due to the complex anatomy of the organ. In addition, a technique for pancreas water T₁ mapping is needed, since the T₁ is biased in the presence of fat. The purpose of this work is to accelerate the acquisition of water selective T₁ (wT₁) mapping for the whole pancreas at 3 T.

Methods

The proposed method combines a continuous inversion-recovery Look-Locker acquisition with a single-shot gradient echo spiral readout, water-fat separation and dictionary matching for wT₁ mapping of the whole pancreas at 3 T. The bias of T₁ in the presence of fat was evaluated in a phantom by comparing the modified Look-Locker inversion-recover
