Magnetization transfer (MT) imaging is one way
of indirectly assessing pools of protons with
extremely fast transverse relaxation. However,
conventional long TE MT imaging sequences are
not applicable to short T2 tissues such as
cortical bone. Ultrashort echo time (UTE)
sequences can detect signal from short T2
species. The combination of UTE with MT (UTE-MT)
provides a valuable option to assess different
bone components. In this study we evaluated
UTE-MT imaging of cortical bone and its
application in assessing cortical porosity and
biomechanical properties of cadaveric human bone
samples using a clinical whole body 3T scanner.
