Magnetic resonance imaging (MRI) offers superior soft-tissue contrast as compared with
computed tomography (CT), which is conventionally used for radiation therapy treatment …

Attenuation correction is an essential component of the long chain of data correction
techniques required to achieve the full potential of quantitative positron emission …

The use of magnetic resonance imaging (MRI) in radiotherapy (RT) planning is rapidly
expanding. We review the wide range of image contrast mechanisms available to MRI and …

Cycle-consistent generative adversarial network (CycleGAN) has been widely used for cross-
domain medical image synthesis tasks particularly due to its ability to deal with unpaired …

Purpose: In radiotherapy (RT) based on magnetic resonance imaging (MRI) as the only
modality, the information on electron density must be derived from the MRI scan by creating …

Simultaneous PET and MR imaging offers unprecedented opportunities to synergize the
physiologic and molecular imaging capability of PET and the excellent anatomic and …

The reconstruction of PET brain data in a PET/MR hybrid scanner is challenging in the
absence of transmission sources, where MR images are used for MR-based attenuation …

The classification and registration of incomplete multi-modal medical images, such as multi-
sequence MRI with missing sequences, can sometimes be improved by replacing the …

Simultaneous PET/MR of the brain is a promising technology for characterizing patients with
suspected cognitive impairment or epilepsy. Unlike CT, however, MR signal intensities do …

Despite being thirteen years since the installation of the first PET-MR system, the scanners
constitute a very small proportion of the total hybrid PET systems installed. This is in stark …
