Calculation of absorbed dose in radiotherapy by solution of the linear Boltzmann transport equations.
(2019-01-10)
Over the last decade, dose calculations which solve the linear Boltzmann transport equations have been introduced into clinical practice and are now in widespread use. However, knowledge in the radiotherapy community ...
Quantitative assessment of patient suitability for magnetic resonance-guided High Intensity Focused Ultrasound Therapy
(Institute of Cancer Research (University Of London), 2021-01-31)
Clinical assessment of a patient's suitability for magnetic resonance-guided high intensity focused ultrasound (MRgHIFU) therapy currently involves subjective judgements based on available diagnostic images and prior ...
The diagnostic value of 18F-FDG-PET/CT and MRI in suspected vertebral osteomyelitis - a prospective study.
(2018-05)
PURPOSE:The aim of this study was to determine the diagnostic value of 18F-fluorodeoxyglucose (FDG) positron emission tomography and computed tomography (PET/CT) and magnetic resonance imaging (MRI) in diagnosing vertebral ...
Imaging of testicular germ cell tumours.
(E-MED LTD, 2006-09-07)
In testicular germ cell tumour (GCT), imaging plays a central role in assessment of tumour bulk, sites of metastases, monitoring response to therapy, surgical planning and accurate assessment of disease at relapse. The ...
Preoperative imaging in patients undergoing trachelectomy for cervical cancer: validation of a combined T2- and diffusion-weighted endovaginal MRI technique at 3.0 T.
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2014-05-01)
AIM: The aim of this study is to validate high-resolution endovaginal T2- and diffusion-weighted MRI measurements (tumour size, volume and length of uninvolved cervical canal) against histology in patients undergoing ...
Advanced magnetic resonance imaging in lung mesothelioma
(Institute of Cancer Research (University Of London), 2021-07-31)
Malignant pleural mesothelioma (MPM) has a rind-like growth pattern and may have both solid disease and pleural fluid, so it is very challenging to accurately categorize change in tumour burden using size-based tumour ...
Novel concepts for automated segmentation to facilitate MRI-guided radiotherapy in head and neck cancer
(Institute of Cancer Research (University Of London), 2019-09-30)
The dramatic increase of magnetic resonance imaging (MRI) in daily treatment planning and response assessment of radiotherapy (RT) requires the development of reliable auto-segmentation algorithms for organs-at-risk (OARs) ...
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, ...
Lung stereotactic body radiotherapy with an MR-linac - Quantifying the impact of the magnetic field and real-time tumor tracking.
(ELSEVIER IRELAND LTD, 2016-06-01)
BACKGROUND AND PURPOSE: There are concerns that radiotherapy doses delivered in a magnetic field might be distorted due to the Lorentz force deflecting secondary electrons. This study investigates this effect on lung ...
Mechanism and non-mechanism based imaging biomarkers for assessing biological response to treatment in non-small cell lung cancer.
(ELSEVIER SCI LTD, 2016-05-01)
Therapeutic options in locally advanced non-small cell lung cancer (NSCLC) have expanded in the past decade to include a palate of targeted interventions such as high dose targeted thermal ablations, radiotherapy and growing ...
