In this abstract we investigate the feasibility of zero
TE imaging for depiction of cortical bone structures in
the head and pelvis. Proton density contrast in
combination with logarithmic inverse scaling is used to
highlight bone structures and differentiate them from
soft tissues and background air. Different from prior
art, no long T2 suppression methods (like echo
subtraction or saturation prepulses) are required,
rendering this method fast, robust and effective.
In-vivo volunteer experiments indicate excellent 3D
cortical bone depiction as required for instance for
PET/MR attenuation correction and MR-based radiation
therapy planning.
