Elevated levels of iron in the body can be detected in various organs including the heart. If not treated, high iron levels can lead to serious health conditions including heart failure and cirrhosis. Cardiovascular MR provides a non-invasive and repeatable alternative method to endomyocardial biopsy for monitoring iron levels within the myocardium.
Multi-echo, single slice, Cartesian acquisitions have previously been developed for cardiovascular iron assessment with MR, but the presence of iron within the myocardium can be heterogeneous . In this work, we present a single breath-hold, multi-echo, multi-slice, spiral acquisition providing large coverage of the heart for the assessment of cardiovascular iron deposition.
The sequence was tested on volunteers to demonstrate the feasibility of the technique. Images were reconstructed with partially parallel imaging with localized sensitivities.
With spiral imaging, a set of T2* weighted images can be acquired over multiple slices in a single breath-hold. Future work includes clinical evaluation.
