One of the main challenges of attenuation correction in
hybrid PET/MR scanners is the correct identification of
bone tissue. A recent development has been the
publication of a new bone identification technique,
based on 3D radial zero echo time (ZTE) imaging. This
sequence provides high-resolution, isotropic images,
suitable for bone segmentation, without the need of
preparation pulses or multiple echoes, making it a very
time-efficient acquisition. The goal of the present
study is to compare ZTE bone images of clinical patients
with the corresponding CT datasets, obtained using a
tri-modality scanner setup.
