Quality of treatment plans and accuracy of in vivo portal dosimetry in hybrid intensity-modulated radiation therapy and volumetric modulated arc therapy for prostate cancer.
(ELSEVIER IRELAND LTD, 2016-08-01)BACKGROUND AND PURPOSE: Delivering selected parts of volumetric modulated arc therapy (VMAT) plans using step-and-shoot intensity modulated radiotherapy (IMRT) beams has the potential to increase plan quality by allowing ... -
Quantification and dosimetry of small volumes including associated uncertainty estimation.
(SPRINGER, 2022-12-13)BACKGROUND: Accurate quantification of radioactivity in a source of interest relies on accurate registration between SPECT and anatomical images, and appropriate correction of partial volume effects (PVEs). For small ... -
Quantification of Differential Response of Tumour and Normal Cells to Microbeam Radiation in the Absence of FLASH Effects.
(MDPI, 2021-06-29)Microbeam radiotherapy (MRT) is a preclinical method of delivering spatially-fractionated radiotherapy aiming to improve the therapeutic window between normal tissue complication and tumour control. Previously, MRT was ... -
Quantification of spatial subclonal interactions enhancing the invasive phenotype of pediatric glioma.
(CELL PRESS, 2022-08-30)Diffuse midline gliomas (DMGs) are highly aggressive, incurable childhood brain tumors. They present a clinical challenge due to many factors, including heterogeneity and diffuse infiltration, complicating disease management. ... -
Quantification of subclonal selection in cancer from bulk sequencing data.
(NATURE PUBLISHING GROUP, 2018-05-28)Subclonal architectures are prevalent across cancer types. However, the temporal evolutionary dynamics that produce tumor subclones remain unknown. Here we measure clone dynamics in human cancers by using computational ... -
Quantifying evidence toward pathogenicity for rare phenotypes: The case of succinate dehydrogenase genes, SDHB and SDHD.
(ELSEVIER SCIENCE INC, 2022-01-01)PURPOSE: The weight of the evidence to attach to observation of a novel rare missense variant in SDHB or SDHD in individuals with the rare neuroendocrine tumors, pheochromocytomas and paragangliomas (PCC/PGL), is uncertain. ... -
Quantifying prediction of pathogenicity for within-codon concordance (PM5) using 7541 functional classifications of BRCA1 and MSH2 missense variants.
(ELSEVIER SCIENCE INC, 2021-11-18)PURPOSE: Conditions and thresholds applied for evidence weighting of within-codon concordance (PM5) for pathogenicity vary widely between laboratories and expert groups. Because of the sparseness of available clinical ... -
Quantifying the Genetic Correlation between Multiple Cancer Types.
(AMER ASSOC CANCER RESEARCH, 2017-09-01)Background: Many cancers share specific genetic risk factors, including both rare high-penetrance mutations and common SNPs identified through genome-wide association studies (GWAS). However, little is known about the ... -
Quantitative analysis of diffusion weighted imaging in rectal cancer during radiotherapy using a magnetic resonance imaging integrated linear accelerator.
(ELSEVIER, 2022-07-01)BACKGROUND AND PURPOSE: Magnetic resonance imaging integrated linear accelerator (MR-Linac) platforms enable acquisition of diffusion weighted imaging (DWI) during treatment providing potential information about treatment ... -
Quantitative Assessment and Prognostic Associations of the Immune Landscape in Ovarian Clear Cell Carcinoma.
(MDPI, 2021-07-30)Ovarian clear cell carcinoma (OCCC) is a rare subtype of epithelial ovarian cancer characterised by a high frequency of loss-of-function ARID1A mutations and a poor response to chemotherapy. Despite their generally low ... -
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 ... -
Quantitative Brain MRI in Congenital Adrenal Hyperplasia: In Vivo Assessment of the Cognitive and Structural Impact of Steroid Hormones.
(2018-04)Context:Brain white matter hyperintensities are seen on routine clinical imaging in 46% of adults with congenital adrenal hyperplasia (CAH). The extent and functional relevance of these abnormalities have not been studied ... -
Quantitative Cell Cycle Analysis Based on an Endogenous All-in-One Reporter for Cell Tracking and Classification.
(CELL PRESS, 2017-05-30)Cell cycle kinetics are crucial to cell fate decisions. Although live imaging has provided extensive insights into this relationship at the single-cell level, the limited number of fluorescent markers that can be used in ... -
Quantitative Dual-Isotope Planar Imaging of Thorium-227 and Radium-223 Using Defined Energy Windows.
(MARY ANN LIEBERT, INC, 2020-09-01)Introduction: Thorium-227 is an alpha-emitting radioisotope with potential therapeutic applications in targeted alpha therapy. Thorium-227 decays to Radium-223, which may have an independent biodistribution to that of the ... -
Quantitative histology analysis of the ovarian tumour microenvironment.
(NATURE PORTFOLIO, 2015-11-17)Concerted efforts in genomic studies examining RNA transcription and DNA methylation patterns have revealed profound insights in prognostic ovarian cancer subtypes. On the other hand, abundant histology slides have been ... -
