Comparison of prostate delineation on multimodality imaging for MR-guided radiotherapy.
(BRITISH INST RADIOLOGY, 2019-03-01)OBJECTIVE:: With increasing incorporation of MRI in radiotherapy, we investigate two MRI sequences for prostate delineation in radiographer-led image guidance. METHODS:: Five therapeutic radiographers contoured the prostate ... -
Comparison of six fit algorithms for the intra-voxel incoherent motion model of diffusion-weighted magnetic resonance imaging data of pancreatic cancer patients.
(PUBLIC LIBRARY SCIENCE, 2018-04-04)The intravoxel incoherent motion (IVIM) model for diffusion-weighted imaging (DWI) MRI data bears much promise as a tool for visualizing tumours and monitoring treatment response. To improve the currently poor precision ... -
Comparison of the dose escalation potential for two hypofractionated radiotherapy regimens for locally advanced pancreatic cancer.
(ELSEVIER IRELAND LTD, 2019-03-08)OBJECTIVES: To determine the potential for dose escalation to a biological equivalent dose BED10 ≅ 100 Gy in hypofractionated radiotherapy for locally advanced pancreatic cancer (LAPC). MATERIALS AND METHODS: Ten unselected ... -
Comparison of three reference methods for the measurement of intracellular pH using 31P MRS in healthy volunteers and patients with lymphoma.
(WILEY-BLACKWELL, 2014-02-01)31P magnetic resonance spectroscopy (31P MRS) can measure intracellular pH (pHi) using the chemical shift difference between pH-dependent inorganic phosphate (Pi) and a pH-independent reference peak. This study compared ... -
Compartmental Model for 223Ra-Dichloride in Patients With Metastatic Bone Disease From Castration-Resistant Prostate Cancer.
(ELSEVIER SCIENCE INC, 2018-06-04)PURPOSE: 223Ra-Dichloride is used for treatment of patients with metastatic bone disease from castration-resistant prostate cancer. The uptake and mechanism of action of 223Ra-Dichloride is not well understood. The aim of ... -
Computational Image Analysis of T-Cell Infiltrates in Resectable Gastric Cancer: Association with Survival and Molecular Subtypes.
(OXFORD UNIV PRESS INC, 2021-01-04)BACKGROUND: Gastric and gastro-esophageal junction cancers (GCs) frequently recur after resection, but markers to predict recurrence risk are missing. T-cell infiltrates have been validated as prognostic markers in other ... -
Computational modelling of the cerebral cortical microvasculature: effect of x-ray microbeams versus broad beam irradiation.
(2017-05)Microbeam Radiation Therapy is an innovative pre-clinical strategy which uses arrays of parallel, tens of micrometres wide kilo-voltage photon beams to treat tumours. These x-ray beams are typically generated on a synchrotron ... -
Computational science-enabled radiological pathology for the non-invasive mapping of tumour heterogeneity in childhood neuroblastoma
(Institute of Cancer Research (University Of London), 2021-01-31)Neuroblastoma is a common childhood solid tumour that accounts for 15% of all cancer paediatric deaths. This thesis addresses key deficiencies in our ability to define, monitor and predict neuroblastoma heterogeneity for ... -
Computer-assisted diagnosis techniques (dermoscopy and spectroscopy-based) for diagnosing skin cancer in adults.
(WILEY, 2018-12-04)BACKGROUND: Early accurate detection of all skin cancer types is essential to guide appropriate management and to improve morbidity and survival. Melanoma and cutaneous squamous cell carcinoma (cSCC) are high-risk skin ... -
Consensus guidelines for the definition, detection and interpretation of immunogenic cell death.
(BMJ PUBLISHING GROUP, 2020-01-01)Cells succumbing to stress via regulated cell death (RCD) can initiate an adaptive immune response associated with immunological memory, provided they display sufficient antigenicity and adjuvanticity. Moreover, multiple ... -
Consistent and invertible deformation vector fields for a breathing anthropomorphic phantom: a post-processing framework for the XCAT phantom.
