A review on methods to estimate a CT from MRI data in the context of MRI-alone RT

Boukellouz Wafa, Abdelouahab Moussaoui
2018 Medical Technologies Journal  
Thus, approaches are focusing on the use of MRI as the only modality in RT. In this paper, we review methods for creating pseudo-CT images from MRI data for MRI-alone RT.  ...  Conclusion: Radiation therapy is emerging towards the generalisation of MRI-only RT thanks to the advances in techniques for generation of pseudo-CT images and the development of specialised MR sequences  ...  Conclusion This paper aimed to review approaches for pseudo-CT generation from MR images for an MRI-only radiotherapy treatment workflow.  ...

2019 arXiv   pre-print
Here we introduce methods to characterise different components of uncertainty in such problems and demonstrate the ideas using diffusion MRI super-resolution.  ...  Results demonstrate that such an uncertainty measure enables subject-specific and voxel-wise risk assessment of the output images.  ...  We would also like to thank Samuel Hurley whom helped with the Prisma acquisitions in FMRIB at University of Oxford.  ...

Exploratory Analysis of Serial 18F-fluciclovine PET-CT and Multiparametric MRI during Chemoradiation for Glioblastoma

Kavi Fatania, Russell Frood, Marcus Tyyger, Garry McDermott, Sharon Fernandez, Gary C. Shaw, Marjorie Boissinot, Daniela Salvatore, Luisa Ottobrini, Irvin Teh, John Wright, Marc A. Bailey (+7 others)
2022 Cancers  
Results suggest volumes of 18F-fluciclovine-PET activity beyond that depicted by DCE-MRI and Gd-T1 are associated with poorer prognosis in patients undergoing chemoradiotherapy for GBM.  ...  For GBM-SS, PET tumour volumes were greater than DCE-MRI, in turn greater than Gd-T1. For GBM-LS, Gd-T1 and DCE-MRI were greater than PET.  ...  The quality of registration was assessed by a Clinical Scientist specialised in radiotherapy planning (with 3 years of experience). The absolute volume of each delineation was determined (cm 3 ).  ...
