Impact of Ga-68-PSMA PET/CT on management in prostate cancer patients with very early biochemical recurrence after radical prostatectomy.
(SPRINGER, 2019-04-01)PURPOSE: With the availability of ultra-sensitive PSA assays, early biochemical relapse (eBCR) of prostate cancer is increasingly being detected at values much lower than the conventional threshold of 0.2 ng/ml. Accurate ... -
Impact of Pelvic Radiation Therapy for Prostate Cancer on Global Metabolic Profiles and Microbiota-Driven Gastrointestinal Late Side Effects: A Longitudinal Observational Study.
(ELSEVIER SCIENCE INC, 2021-12-01)PURPOSE: Radiation therapy to the prostate and pelvic lymph nodes (PLNRT) is part of the curative treatment of high-risk prostate cancer. Yet, the broader influence of radiation therapy on patient physiology is poorly ... -
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 ... -
Improvements in molecular diagnostics and image analysis for detecting and managing cervical cancer
(Institute of Cancer Research (University Of London), 2020-12-31)This thesis addresses improvements in molecular diagnostics and in image analysis, and their combination for managing cervical cancer. Screening cytology has transformed early diagnosis but is resource intensive and highly ... -
Improving 3D ultrasound prostate localisation in radiotherapy through increased automation of interfraction matching.
(ELSEVIER IRELAND LTD, 2020-08-01)BACKGROUND AND PURPOSE: Daily image guidance is standard care for prostate radiotherapy. Innovations which improve the accuracy and efficiency of ultrasound guidance are needed, particularly with respect to reducing ... -
Improving fiducial and prostate capsule visualization for radiotherapy planning using MRI.
(WILEY, 2019-03-01)BACKGROUND AND PURPOSE: Intraprostatic fiducial markers (FM) improve the accuracy of radiotherapy (RT) delivery. Here we assess geometric integrity and contouring consistency using a T2*-weighted (T2*W) sequence alone, ... -
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 ... -
In transit metastases in children, adolescents and young adults with localized rhabdomyosarcoma of the distal extremities: Analysis of the EpSSG RMS 2005 study.
(2022-03-12)In-transit metastases (ITM) are defined as metastatic lymph nodes or deposits occurring between the primary tumor and proximal draining lymph node basin. In extremity rhabdomyosarcoma (RMS), they have rarely been reported. ... -
In vitro characterisation of ultrasound-induced heating effects in the mother and fetus: A clinical perspective.
(SAGE PUBLICATIONS LTD, 2020-09-14)INTRODUCTION: The quantification of heating effects during exposure to ultrasound is usually based on laboratory experiments in water and is assessed using extrapolated parameters such as the thermal index. In our study, ... -
In Vivo Characterization of 4 68Ga-Labeled Multimeric RGD Peptides to Image αvβ3 Integrin Expression in 2 Human Tumor Xenograft Mouse Models.
(2018-08)αvβ3 integrins play an important role in angiogenesis and cell migration in cancer and are highly expressed on the activated endothelial cells of newly formed blood vessels. Here, we compare the targeting characteristics ... -
In Vivo Modeling of Chemoresistant Neuroblastoma Provides New Insights into Chemorefractory Disease and Metastasis.
(AMER ASSOC CANCER RESEARCH, 2019-10-15)Neuroblastoma is a pediatric cancer that is frequently metastatic and resistant to conventional treatment. In part, a lack of natively metastatic, chemoresistant in vivo models has limited our insight into the development ... -
In-vivo EPID dosimetry for IMRT and VMAT based on through-air predicted portal dose algorithm.
(ELSEVIER SCI LTD, 2018-08-01)We have adapted the methodology of Berry et al. (2012) for Intensity Modulated Radiotherapy (IMRT) and Volumetric Modulated Arc Therapy (VMAT) treatments at a fixed source to imager distance (SID) based on the manufacturer's ... -
Inclusion of a Charge Sharing Correction Algorithm Into an X-Ray Photon Counting Spectral Detector Simulation Framework
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2021-07-01) -
Incorporating radiomics into clinical trials: expert consensus endorsed by the European Society of Radiology on considerations for data-driven compared to biologically driven quantitative biomarkers.
(SPRINGER, 2021-01-25)Existing quantitative imaging biomarkers (QIBs) are associated with known biological tissue characteristics and follow a well-understood path of technical, biological and clinical validation before incorporation into ... -
Incorporating spatial dose metrics in machine learning-based normal tissue complication probability (NTCP) models of severe acute dysphagia resulting from head and neck radiotherapy.
(ELSEVIER IRELAND LTD, 2018-01-01)Severe acute dysphagia commonly results from head and neck radiotherapy (RT). A model enabling prediction of severity of acute dysphagia for individual patients could guide clinical decision-making. Statistical associations ... -
Increased Dose to Organs in Urinary Tract Associates With Measures of Genitourinary Toxicity in Pooled Voxel-Based Analysis of 3 Randomized Phase III Trials.
(FRONTIERS MEDIA SA, 2020-07-22)Purpose: Dose information from organ sub-regions has been shown to be more predictive of genitourinary toxicity than whole organ dose volume histogram information. This study aimed to identify anatomically-localized regions ... -
Independent component analysis (ICA) applied to dynamic oxygen-enhanced MRI (OE-MRI) for robust functional lung imaging at 3 T.
(WILEY, 2024-03-01)PURPOSE: Dynamic lung oxygen-enhanced MRI (OE-MRI) is challenging due to the presence of confounding signals and poor signal-to-noise ratio, particularly at 3 T. We have created a robust pipeline utilizing independent ... -
