Computed tomography is the current gold-standard for
imaging kidney stones, albeit at the cost of radiation
exposure. Conventional MRI sequences are insensitive to
detecting kidney stones because their appearance as
signal void. With the development of 2D ultra-short
echo-time (UTE) MRI sequences, it becomes possible to
image kidney stones in-vitro, despite the limitations of
long scan-time and low sensitivity for stone detection.
In this work, we optimize and implement a modified 3D
UTE sequence for high-resolution in-vitro imaging of
kidney stones at 3.0T while avoiding the previously
mentioned limitations, which makes this sequence a
candidate for imaging kidney stone patients.
