Detecting gas-induced vasomotor changes via blood oxygenation level-dependent contrast in healthy breast parenchyma and breast carcinoma.
(WILEY-BLACKWELL, 2016-08-01)PURPOSE: To evaluate blood oxygenation level-dependent (BOLD) contrast changes in healthy breast parenchyma and breast carcinoma during administration of vasoactive gas stimuli. MATERIALS AND METHODS: Magnetic resonance ... -
Polygenic risk scores and breast and epithelial ovarian cancer risks for carriers of BRCA1 and BRCA2 pathogenic variants.
(ELSEVIER SCIENCE INC, 2020-10-01)PURPOSE: We assessed the associations between population-based polygenic risk scores (PRS) for breast (BC) or epithelial ovarian cancer (EOC) with cancer risks for BRCA1 and BRCA2 pathogenic variant carriers. METHODS: ... -
Diffusion-weighted MRI in Advanced Epithelial Ovarian Cancer: Apparent Diffusion Coefficient as a Response Marker.
(2019-11)Background Treatment of advanced epithelial ovarian cancer results in a relapse rate of 75%. Early markers of response would enable optimization of management and improved outcome in both primary and recurrent disease. ... -
Repeatability and reproducibility of longitudinal relaxation rate in 12 small-animal MRI systems.
(ELSEVIER SCIENCE INC, 2019-06-01)BACKGROUND: Many translational MR biomarkers derive from measurements of the water proton longitudinal relaxation rate R1, but evidence for between-site reproducibility of R1 in small-animal MRI is lacking. OBJECTIVE: To ... -
Do imaging biomarkers relate to outcome in patients treated with VEGF inhibitors?
(AMER ASSOC CANCER RESEARCH, 2012-12-15)The management of solid tumors has been transformed by the advent of VEGF pathway inhibitors. Early clinical evaluation of these drugs has used pharmacodynamic biomarkers derived from advanced imaging such as dynamic MRI, ... -
A reformulation of pLSA for uncertainty estimation and hypothesis testing in bio-imaging.
(OXFORD UNIV PRESS, 2020-07-01)MOTIVATION: Probabilistic latent semantic analysis (pLSA) is commonly applied to describe mass spectra (MS) images. However, the method does not provide certain outputs necessary for the quantitative scientific interpretation ... -
Reliability and prognostic value of radiomic features are highly dependent on choice of feature extraction platform.
(SPRINGER, 2020-11-01)OBJECTIVE: To investigate the effects of Image Biomarker Standardisation Initiative (IBSI) compliance, harmonisation of calculation settings and platform version on the statistical reliability of radiomic features and their ... -
Radiomics as a personalized medicine tool in lung cancer: Separating the hope from the hype.
(ELSEVIER IRELAND LTD, 2020-08-01)Radiomics has become a popular image analysis method in the last few years. Its key hypothesis is that medical images harbor biological, prognostic and predictive information that is not revealed upon visual inspection. ... -
Whole-exome sequencing reveals the mutational spectrum of testicular germ cell tumours.
(NATURE PUBLISHING GROUP, 2015-01-22)Testicular germ cell tumours (TGCTs) are the most common cancer in young men. Here we perform whole-exome sequencing (WES) of 42 TGCTs to comprehensively study the cancer's mutational profile. The mutation rate is uniformly ... -
FDG PET/CT: EANM procedure guidelines for tumour imaging: version 2.0.
(2015-02)The purpose of these guidelines is to assist physicians in recommending, performing, interpreting and reporting the results of FDG PET/CT for oncological imaging of adult patients. PET is a quantitative imaging technique ... -
Issues involved in the quantitative 3D imaging of proton doses using optical CT and chemical dosimeters.
(IOP PUBLISHING LTD, 2015-01-21)Dosimetry of proton beams using 3D imaging of chemical dosimeters is complicated by a variation with proton linear energy transfer (LET) of the dose-response (the so-called 'quenching effect'). Simple theoretical arguments ... -
Combined MYC and P53 defects emerge at medulloblastoma relapse and define rapidly progressive, therapeutically targetable disease.
(CELL PRESS, 2015-01-12)We undertook a comprehensive clinical and biological investigation of serial medulloblastoma biopsies obtained at diagnosis and relapse. Combined MYC family amplifications and P53 pathway defects commonly emerged at relapse, ... -
Failing to Close the Gap Between Evidence and Clinical Practice in Radical Bladder Cancer Radiotherapy.

Prospective, longitudinal, multi-modal functional imaging for radical chemo-IMRT treatment of locally advanced head and neck cancer: the INSIGHT study.
(BIOMED CENTRAL LTD, 2015-05-15)BACKGROUND: Radical chemo-radiotherapy (CRT) is an effective organ-sparing treatment option for patients with locally advanced head and neck cancer (LAHNC). Despite advances in treatment for LAHNC, a significant minority ... -
Diffusion-weighted MRI for imaging cell death after cytotoxic or apoptosis-inducing therapy.
(NATURE PUBLISHING GROUP, 2015-04-28)BACKGROUND: Non-invasive serial imaging is desirable to detect processes such as necrotic and apoptotic cell death in cancer patients undergoing treatment. This study investigated the use of diffusion-weighted (DW-) magnetic ... -
Exploration of the treatment challenges in men with intellectual difficulties and testicular cancer as seen in Down syndrome: single centre experience.
(BMC, 2015-06-26)Down syndrome is the most common chromosomal disorder in humans as well as the most common cause of inherited intellectual disability. A spectrum of physical and functional disability is associated with the syndrome as ... -
Fast CPU-based Monte Carlo simulation for radiotherapy dose calculation.
(2015-08)Monte-Carlo (MC) simulations are considered to be the most accurate method for calculating dose distributions in radiotherapy. Its clinical application, however, still is limited by the long runtimes conventional implementations ... -
Hypofractionated radiotherapy versus conventionally fractionated radiotherapy for patients with intermediate-risk localised prostate cancer: 2-year patient-reported outcomes of the randomised, non-inferiority, phase 3 CHHiP trial.
(ELSEVIER SCIENCE INC, 2015-12-01)BACKGROUND: Patient-reported outcomes (PROs) might detect more toxic effects of radiotherapy than do clinician-reported outcomes. We did a quality of life (QoL) substudy to assess PROs up to 24 months after conventionally ... -
