In this study, we propose a highly time efficient quantitative imaging
scheme where short and long T2* components can be simultaneously estimated. This
method is based on a multi-echo UTE hybrid encoding scheme, where the central
SPI region is oversampled to allow measurement of short T2* across a wide range
of TEs. The UTE acquisition is immediately followed by a gradient echo train to
measure long T2*. We show the proposed method can obtain an extensive number of
images (e.g., approximately 750 images) within a single acquisition and
reasonable scan time.
