Evaluation of a multi-atlas CT synthesis approach for MRI-only radiotherapy treatment planning.
(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 ... -
An evaluation of contouring and planning methods to expand the role of SBRT with CyberKnife in the treatment of localised prostate and renal cancers
(Institute of Cancer Research (University Of London), 2022-05-31)Technological advancement has led to the substantial evolution of stereotactic body radiotherapy (SBRT). The CyberKnife SBRT platform achieves a high degree of precision through robotic delivery of multiple non-coplanar ... -
Evaluation of DFO-HOPO as an octadentate chelator for zirconium-89.
(ROYAL SOC CHEMISTRY, 2017-07-27)The future of 89Zr-based immuno-PET is reliant upon the development of new chelators with improved stability compared to the currently used deferoxamine (DFO). Herein, we report the evaluation of the octadentate molecule ... -
Evaluation of diffusion models in breast cancer.
(WILEY, 2015-08-01)PURPOSE: The purpose of this study is to investigate whether the microvascular pseudodiffusion effects resulting with non-monoexponential behavior are present in breast cancer, taking into account tumor spatial heterogeneity. ... -
Evaluation of diffusion-weighted MRI and (18F) fluorothymidine-PET biomarkers for early response assessment in patients with operable non-small cell lung cancer treated with neoadjuvant chemotherapy.
(Oxford University Press (OUP), 2019-01-01)OBJECTIVE: To correlate changes in the apparent diffusion coefficient (ADC) from diffusion-weighted (DW)-MRI and standardised uptake value (SUV) from fluorothymidine (18FLT)-PET/CT with histopathological estimates of ... -
Evaluation of dynamic contrast-enhanced MRI biomarkers for stratified cancer medicine: How do permeability and perfusion vary between human tumours?
(ELSEVIER SCIENCE INC, 2018-02-01)BACKGROUND: Solid tumours exhibit enhanced vessel permeability and fenestrated endothelium to varying degree, but it is unknown how this varies in patients between and within tumour types. Dynamic contrast-enhanced (DCE) ... -
Evaluation of dysphagia-optimising radiotherapy techniques in locally advanced oropharyngeal cancer
(Institute of Cancer Research (University Of London), 2020-01-31)Radiation-associated dysphagia (RAD) following chemoradiation in locally advanced oropharyngeal cancers (LA-OPC) can have a devastating impact on patients' quality of life (QoL). Establishing efficient swallow-sparing ... -
