3-D Microvascular Imaging Using High Frame Rate Ultrasound and ASAP Without Contrast Agents: Development and Initial In Vivo Evaluation on Nontumor and Tumor Models.
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2019-05-01)Three-dimensional imaging is valuable to noninvasively assess angiogenesis given the complex 3-D architecture of vascular networks. The emergence of high frame rate (HFR) ultrasound, which can produce thousands of images ... -
3-Dimensional objective aesthetic evaluation to replace panel assessment after breast-conserving treatment.
(2020-11)Background Two-thirds of patients with early breast cancer undergo breast-conserving treatment (BCT). Aesthetic outcome is important and has long term implications for psychosocial wellbeing. The aesthetic goal of BCT is ... -
3D tumour spheroids for the prediction of the effects of radiation and hyperthermia treatments.
(NATURE PORTFOLIO, 2020-02-03)For multimodality therapies such as the combination of hyperthermia and radiation, quantification of biological effects is key for dose prescription and response prediction. Tumour spheroids have a microenvironment that ... -
4D-MRI for thoracic radiotherapy treatment planning and guidance on an MR-linac
Lung cancer currently has a poor prognosis in England and Wales with only 10% of adults surviving five years or more after diagnosis. The poor survival rate demonstrates the need to improve contemporary treatment approaches ... -
5-fraction radiotherapy for breast cancer: FAST Forward to implementation.
(Elsevier, 2023-05-19) -
A Canadian approach to the regionalization of testis cancer: A review.
(2020-10)At the Canadian Testis Cancer Workshop, the rationale and feasibility of regionalization of testis cancer care were discussed. The two-day workshop involved urologists, medical and radiation oncologists, pathologists, ... -
A cellular automaton model for spheroid response to radiation and hyperthermia treatments.
(NATURE PORTFOLIO, 2019-11-27)Thermo-radiosensitisation is a promising approach for treatment of radio-resistant tumours such as those containing hypoxic subregions. Response prediction and treatment planning should account for tumour response ... -
A comparison of machine learning methods for predicting recurrence and death after curative-intent radiotherapy for non-small cell lung cancer: Development and validation of multivariable clinical prediction models.
(ELSEVIER, 2022-03-03)BACKGROUND: Surveillance is universally recommended for non-small cell lung cancer (NSCLC) patients treated with curative-intent radiotherapy. High-quality evidence to inform optimal surveillance strategies is lacking. ... -
A comparison of the diagnostic value of MRI and 18 F-FDG-PET/CT in suspected spondylodiscitis.
(2017-02)Purpose The purpose of this study was to evaluate the diagnostic value of 18 F-fluorodeoxyglucose (FDG) positron emission tomography and computed tomography (PET/CT scan) and magnetic resonance imaging (MRI) in diagnosing ... -
A comprehensive model for heat-induced radio-sensitisation.
(TAYLOR & FRANCIS LTD, 2017-07-05)Combined radiotherapy (RT) and hyperthermia (HT) treatments may improve treatment outcome by heat induced radio-sensitisation. We propose an empirical cell survival model (AlphaR model) to describe this multimodality ... -
A computerized volumetric segmentation method applicable to multi-centre MRI data to support computer-aided breast tissue analysis, density assessment and lesion localization.
(SPRINGER HEIDELBERG, 2017-01-01)Density assessment and lesion localization in breast MRI require accurate segmentation of breast tissues. A fast, computerized algorithm for volumetric breast segmentation, suitable for multi-centre data, has been developed, ... -
A convolutional neural network for contouring metastatic lymph nodes on diffusion-weighted magnetic resonance images for assessment of radiotherapy response.
(ELSEVIER, 2020-07-01)BACKGROUND AND PURPOSE: Retrieving quantitative parameters from magnetic resonance imaging (MRI), e.g. for early assessment of radiotherapy treatment response, necessitates contouring regions of interest, which is ... -
A Cross-Cancer Genetic Association Analysis of the DNA Repair and DNA Damage Signaling Pathways for Lung, Ovary, Prostate, Breast, and Colorectal Cancer.
(AMER ASSOC CANCER RESEARCH, 2016-01-01)BACKGROUND: DNA damage is an established mediator of carcinogenesis, although genome-wide association studies (GWAS) have identified few significant loci. This cross-cancer site, pooled analysis was performed to increase ... -
A Cross-Machine Comparison of Shear-Wave Speed Measurements Using 2D Shear-Wave Elastography in the Normal Female Breast
(MDPI, 2021-10-01)<jats:p>Quantitative measures of radiation-induced breast stiffness are required to support clinical studies of novel breast radiotherapy regimens and exploration of personalised therapy, however, variation between shear-wave ... -
A data-driven statistical model that estimates measurement uncertainty improves interpretation of ADC reproducibility: a multi-site study of liver metastases.
(NATURE PORTFOLIO, 2017-10-26)Apparent Diffusion Coefficient (ADC) is a potential quantitative imaging biomarker for tumour cell density and is widely used to detect early treatment changes in cancer therapy. We propose a strategy to improve confidence ... -
A Dosimetric Comparison of Breast Radiotherapy Techniques to Treat Locoregional Lymph Nodes Including the Internal Mammary Chain.
(ELSEVIER SCIENCE LONDON, 2018-06-01)AIMS: Radiotherapy target volumes in early breast cancer treatment increasingly include the internal mammary chain (IMC). In order to maximise survival benefits of IMC radiotherapy, doses to the heart and lung should be ... -
A dosimetric comparison of real-time adaptive and non-adaptive radiotherapy: A multi-institutional study encompassing robotic, gimbaled, multileaf collimator and couch tracking.
