Deep Learning Framework with Multi-Head Dilated Encoders for Enhanced Segmentation of Cervical Cancer on Multiparametric Magnetic Resonance Imaging.
(MDPI, 2023-11-03)T2-weighted magnetic resonance imaging (MRI) and diffusion-weighted imaging (DWI) are essential components of cervical cancer diagnosis. However, combining these channels for the training of deep learning models is challenging ... -
Boosting and broadening recruitment to UK cancer trials: towards a blueprint for action
(BMJ, 2023-11-01)<jats:p>Recruitment and retention in cancer trials are long-standing issues, exacerbated by the COVID-19 pandemic. The UK National Institute of Health Research and leading clinicians have emphasised the urgency to achieve ... -
Relative fat fraction of malignant bone lesions from breast cancer, prostate cancer and myeloma are significantly lower than normal bone marrow and shows excellent interobserver agreement.
(BRITISH INST RADIOLOGY, 2023-11-01)OBJECTIVES: To compare relative fat fraction (rFF) of active bone lesions from breast, prostate and myeloma malignancies and normal bone marrow; to assess its inter-reader agreement. METHODS: Patients with breast (n = 26), ... -
Respiratory motion modelling for MR-guided lung cancer radiotherapy: model development and geometric accuracy evaluation.
(IOP Publishing Ltd, 2024-02-19)Objective.Respiratory motion of lung tumours and adjacent structures is challenging for radiotherapy. Online MR-imaging cannot currently provide real-time volumetric information of the moving patient anatomy, therefore ... -
Improving tumour target coverage in spine stereotactic radiotherapy
(Institute of Cancer Research (University Of London), 2024-01-16)Spine stereotactic body radiotherapy (SBRT) has high rates of local control. Local control failure rates are higher in cases with epidural disease and radioresistant histologies. A limiting factor is the proximity of the ... -
Defining novel immune biomarkers of prognosis and immunotherapy sensitivity in gastro-oesophageal and colorectal cancers
(Institute of Cancer Research (University Of London), 2023-11-28)Background Gastro-oesophageal adenocarcinomas (GOAs) frequently recur after resection; prognostic and predictive markers are absent. Mismatch repair-deficient (MMRd) GOAs have high mutational burden, are frequently ... -
