Bone water exists in the form of free water
in the Haversian canals or lacunar-canalicular system, as well as bound water either loosely
bound to collagen or more tightly bound to mineral. Ultrashort echo time (UTE)
sequences with TEs as short as 8 µs can potentially detect signal from pore
water and loosely bound water. In this study, we introduce an approach for fast
volumetric mapping of bound and pore water content in vivo using a clinical 3T
MR scanner.
