With the development of ultra-short echo-time (UTE) MRI
sequences, adequate imaging of kidney stones becomes
possible. Although few studies investigated imaging
stones in certain experimental settings (in gel phantoms
using volumetric coils), no study so far investigated
the results of imaging stones with natural surroundings
(inside kidneys) and using the body surface coil, which
is the purpose of this work. The results show that MRI
has the potential for imaging stones of different types
and sizes. If successful for in-vivo imaging, the
developed technique could be a valuable alternative to
CT for imaging patients with higher sensitivity to
radiation exposure.
