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 ...
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 ...
Oxygen-enhanced MRI Is Feasible, Repeatable, and Detects Radiotherapy-induced Change in Hypoxia in Xenograft Models and in Patients with Non-small Cell Lung Cancer.
(AMER ASSOC CANCER RESEARCH, 2019-07-01)
PURPOSE: Hypoxia is associated with poor prognosis and is predictive of poor response to cancer treatments, including radiotherapy. Developing noninvasive biomarkers that both detect hypoxia prior to treatment and track ...
Inter-observer agreement of baseline whole body MRI in multiple myeloma.
(BMC, 2020-07-14)
BACKGROUND: Whole body magnetic resonance imaging (MRI) is now incorporated into international guidance for imaging patients with multiple myeloma. The aim of this study was to investigate inter-observer agreement of triple ...
Radioactive 3D printing for the production of molecular imaging phantoms.
(IOP Publishing Ltd, 2020-09-08)
Quality control tests of molecular imaging systems are hampered by the complexity of phantom preparation. It is proposed that radioisotopes can be directly incorporated into photo-polymer resins. Use of the radio-polymer ...
Strategies and technical challenges for imaging oligometastatic disease: Recommendations from the European Organisation for Research and Treatment of Cancer imaging group.
(ELSEVIER SCI LTD, 2018-03-01)
Patients with oligometastatic disease (OMD) often have controllable symptoms, and cures are possible. Technical improvements in surgery and radiotherapy have introduced the option of metastasis-directed ablative therapies ...
Implementing diffusion-weighted MRI for body imaging in prospective multicentre trials: current considerations and future perspectives.
(SPRINGER, 2018-03-01)
UNLABELLED: For body imaging, diffusion-weighted MRI may be used for tumour detection, staging, prognostic information, assessing response and follow-up. Disease detection and staging involve qualitative, subjective ...
Genetically modified lentiviruses that preserve microvascular function protect against late radiation damage in normal tissues.
(AMER ASSOC ADVANCEMENT SCIENCE, 2018-01-24)
Improvements in cancer survival mean that long-term toxicities, which contribute to the morbidity of cancer survivorship, are being increasingly recognized. Late adverse effects (LAEs) in normal tissues after radiotherapy ...
