Clinical development of new drug-radiotherapy combinations.
(NATURE PUBLISHING GROUP, 2016-10-01)
In countries with the best cancer outcomes, approximately 60% of patients receive radiotherapy as part of their treatment, which is one of the most cost-effective cancer treatments. Notably, around 40% of cancer cures ...
Oxygen-Enhanced MRI Accurately Identifies, Quantifies, and Maps Tumor Hypoxia in Preclinical Cancer Models.
(AMER ASSOC CANCER RESEARCH, 2015-11-19)
There is a clinical need for noninvasive biomarkers of tumor hypoxia for prognostic and predictive studies, radiotherapy planning, and therapy monitoring. Oxygen-enhanced MRI (OE-MRI) is an emerging imaging technique for ...
Targeting Hypoxia to Improve Non-Small Cell Lung Cancer Outcome.
(OXFORD UNIV PRESS INC, 2018-01-01)
Oxygen deprivation (hypoxia) in non-small cell lung cancer (NSCLC) is an important factor in treatment resistance and poor survival. Hypoxia is an attractive therapeutic target, particularly in the context of radiotherapy, ...
Repeatability and reproducibility of longitudinal relaxation rate in 12 small-animal MRI systems.
(ELSEVIER SCIENCE INC, 2019-06-01)
BACKGROUND: Many translational MR biomarkers derive from measurements of the water proton longitudinal relaxation rate R1, but evidence for between-site reproducibility of R1 in small-animal MRI is lacking. OBJECTIVE: To ...
Oxygen Enhanced Optoacoustic Tomography (OE-OT) Reveals Vascular Dynamics in Murine Models of Prostate Cancer.
(IVYSPRING INT PUBL, 2017-01-01)
Poor oxygenation of solid tumours has been linked with resistance to chemo- and radio-therapy and poor patient outcomes, hence non-invasive imaging of oxygen supply and demand in tumours could improve disease staging and ...
Cancer heterogeneity and imaging.
(ACADEMIC PRESS LTD- ELSEVIER SCIENCE LTD, 2017-04-01)
There is interest in identifying and quantifying tumor heterogeneity at the genomic, tissue pathology and clinical imaging scales, as this may help better understand tumor biology and may yield useful biomarkers for guiding ...
Data-driven mapping of hypoxia-related tumor heterogeneity using DCE-MRI and OE-MRI.
(WILEY, 2018-04-01)
PURPOSE: Previous work has shown that combining dynamic contrast-enhanced (DCE)-MRI and oxygen-enhanced (OE)-MRI binary enhancement maps can identify tumor hypoxia. The current work proposes a novel, data-driven method for ...
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) ...
Detecting gas-induced vasomotor changes via blood oxygenation level-dependent contrast in healthy breast parenchyma and breast carcinoma.
(WILEY-BLACKWELL, 2016-08-01)
PURPOSE: To evaluate blood oxygenation level-dependent (BOLD) contrast changes in healthy breast parenchyma and breast carcinoma during administration of vasoactive gas stimuli. MATERIALS AND METHODS: Magnetic resonance ...
Reliability and prognostic value of radiomic features are highly dependent on choice of feature extraction platform.
(SPRINGER, 2020-11-01)
OBJECTIVE: To investigate the effects of Image Biomarker Standardisation Initiative (IBSI) compliance, harmonisation of calculation settings and platform version on the statistical reliability of radiomic features and their ...
