Consistent and invertible deformation vector fields for a breathing anthropomorphic phantom: a post-processing framework for the XCAT phantom.
(IOP PUBLISHING LTD, 2020-08-13)
Breathing motion is challenging for radiotherapy planning and delivery. This requires advanced four-dimensional (4D) imaging and motion mitigation strategies and associated validation tools with known deformations. Numerical ...
Tumour auto-contouring on 2d cine MRI for locally advanced lung cancer: A comparative study.
(ELSEVIER IRELAND LTD, 2017-12-01)
BACKGROUND AND PURPOSE: Radiotherapy guidance based on magnetic resonance imaging (MRI) is currently becoming a clinical reality. Fast 2d cine MRI sequences are expected to increase the precision of radiation delivery by ...
Validated imaging biomarkers as decision-making tools in clinical trials and routine practice: current status and recommendations from the EIBALL* subcommittee of the European Society of Radiology (ESR).
(SPRINGER, 2019-08-29)
Observer-driven pattern recognition is the standard for interpretation of medical images. To achieve global parity in interpretation, semi-quantitative scoring systems have been developed based on observer assessments; ...
Height, selected genetic markers and prostate cancer risk: results from the PRACTICAL consortium.
(NATURE PUBLISHING GROUP, 2017-08-22)
BACKGROUND: Evidence on height and prostate cancer risk is mixed, however, recent studies with large data sets support a possible role for its association with the risk of aggressive prostate cancer. METHODS: We analysed ...
Chemical- and radiation-induced haemorrhagic cystitis: current treatments and challenges.
(WILEY, 2013-11-01)
• To review the published data on predisposing risk factors for cancer treatment-induced haemorrhagic cystitis (HC) and the evidence for the different preventive and therapeutic measures that have been used in order to ...
The Patient Deficit Model Overturned: a qualitative study of patients' perceptions of invitation to participate in a randomized controlled trial comparing selective bladder preservation against surgery in muscle invasive bladder cancer (SPARE, CRUK/07/011).
(2012-11-29)
Background Evidence suggests that poor recruitment into clinical trials rests on a patient 'deficit' model - an inability to comprehend trial processes. Poor communication has also been cited as a possible barrier to ...
Beam modeling and VMAT performance with the Agility 160-leaf multileaf collimator.
(2013-05-06)
The Agility multileaf collimator (Elekta AB, Stockholm, Sweden) has 160 leaves of projected width 0.5 cm at the isocenter, with maximum leaf speed 3.5 cms-1. These characteristics promise to facilitate fast and accurate ...
Assessment of the direct effects of DDAH I on tumour angiogenesis in vivo.
(SPRINGER, 2018-11-01)
Nitric oxide (NO) has been strongly implicated in glioma progression and angiogenesis. The endogenous inhibitors of NO synthesis, asymmetric dimethylarginine (ADMA) and N-monomethyl-L-arginine (L-NMMA), are metabolized by ...
Mapping Hypoxia in Renal Carcinoma with Oxygen-enhanced MRI: Comparison with Intrinsic Susceptibility MRI and Pathology.
(RADIOLOGICAL SOC NORTH AMERICA, 2018-09-01)
Purpose To cross-validate T1-weighted oxygen-enhanced (OE) MRI measurements of tumor hypoxia with intrinsic susceptibility MRI measurements and to demonstrate the feasibility of translation of the technique for patients. ...
Dose-limiting Urinary Toxicity With Pembrolizumab Combined With Weekly Hypofractionated Radiation Therapy in Bladder Cancer.
(ELSEVIER SCIENCE INC, 2018-08-01)
There is currently significant interest in the potential benefits of combining radiation and immune checkpoint blockade (ICB) to stimulate both regional and distant abscopal immune responses. In melanoma and lung cancer, ...
