Evaluation of a multi-atlas CT synthesis approach for MRI-only radiotherapy treatment planning.
Guerreiro, F; Burgos, N; Dunlop, A; Wong, K; Petkar, I; et al. (ELSEVIER SCI LTD, 2017-03-01)BACKGROUND AND PURPOSE: Computed tomography (CT) imaging is the current gold standard for radiotherapy treatment planning (RTP). The establishment of a magnetic resonance imaging (MRI) only RTP workflow requires the ... -
Imaging biomarker roadmap for cancer studies.
O'Connor, JPB; Aboagye, EO; Adams, JE; Aerts, HJWL; Barrington, SF; et al. (NATURE PORTFOLIO, 2017-03-01)Imaging biomarkers (IBs) are integral to the routine management of patients with cancer. IBs used daily in oncology include clinical TNM stage, objective response and left ventricular ejection fraction. Other CT, MRI, PET ... -
Iterative framework for the joint segmentation and CT synthesis of MR images: application to MRI-only radiotherapy treatment planning.
Burgos, N; Guerreiro, F; McClelland, J; Presles, B; Modat, M; et al. (IOP PUBLISHING LTD, 2017-06-07)To tackle the problem of magnetic resonance imaging (MRI)-only radiotherapy treatment planning (RTP), we propose a multi-atlas information propagation scheme that jointly segments organs and generates pseudo x-ray computed ... -
Standard and Hypofractionated Dose Escalation to Intraprostatic Tumor Nodules in Localized Prostate Cancer: Efficacy and Toxicity in the DELINEATE Trial.
Murray, JR; Tree, AC; Alexander, EJ; Sohaib, A; Hazell, S; et al. (ELSEVIER SCIENCE INC, 2020-03-15)PURPOSE: To report a planned analysis of the efficacy and toxicity of dose escalation to the intraprostatic dominant nodule identified on multiparametric magnetic resonance imaging using standard and hypofractionated ... -
The PROFILE Feasibility Study: Targeted Screening of Men With a Family History of Prostate Cancer.
Castro, E; Mikropoulos, C; Bancroft, EK; Dadaev, T; Goh, C; et al. (WILEY, 2016-06-01)BACKGROUND: A better assessment of individualized prostate cancer (PrCa) risk is needed to improve screening. The use of the prostate-specific antigen (PSA) level for screening in the general population has limitations and ... -
Validation of T2- and diffusion-weighted magnetic resonance imaging for mapping intra-prostatic tumour prior to focal boost dose-escalation using intensity-modulated radiotherapy (IMRT).
Alexander, EJ; Murray, JR; Morgan, VA; Giles, SL; Riches, SF; et al. (ELSEVIER IRELAND LTD, 2019-12-01)BACKGROUND AND PURPOSE: To assess the diagnostic accuracy and inter-observer agreement of T2-weighted (T2W) and diffusion-weighted (DW) magnetic resonance imaging (MRI) for mapping intra-prostatic tumour lesions (IPLs) for ... -
Volumetry of the dominant intraprostatic tumour lesion: intersequence and interobserver differences on multiparametric MRI.
Harvey, H; Orton, MR; Morgan, VA; Parker, C; Dearnaley, D; et al. (BRITISH INST RADIOLOGY, 2017-03-01)OBJECTIVE: To establish the interobserver reproducibility of tumour volumetry on individual multiparametric (mp) prostate MRI sequences, validate measurements with histology and determine whether functional to morphological ... -
Whole-body diffusion-weighted MR imaging for assessment of treatment response in myeloma.
Giles, SL; Messiou, C; Collins, DJ; Morgan, VA; Simpkin, CJ; et al. (RADIOLOGICAL SOC NORTH AMERICA, 2014-06-01)PURPOSE: To determine the feasibility of whole-body diffusion-weighted (DW) magnetic resonance (MR) imaging for assessment of treatment response in myeloma. MATERIALS AND METHODS: This prospective single-institution study ...
