Diagnostic accuracy of deep learning in medical imaging: a systematic review and meta-analysis.
(2021-04-07)Deep learning (DL) has the potential to transform medical diagnostics. However, the diagnostic accuracy of DL is uncertain. Our aim was to evaluate the diagnostic accuracy of DL algorithms to identify pathology in medical ... -
Diagnostic Accuracy of FEC-PET/CT, FDG-PET/CT, and Diffusion-Weighted MRI in Detection of Nodal Metastases in Surgically Treated Endometrial and Cervical Carcinoma.
(2021-09-15)Purpose Preoperative nodal staging is important for planning treatment in cervical cancer and endometrial cancer, but remains challenging. We compare nodal staging accuracy of 18 F-ethyl-choline-(FEC)-PET/CT, 18 ... -
Diagnostic accuracy of multi-parametric MRI and TRUS biopsy in prostate cancer (PROMIS): a paired validating confirmatory study.
(2017-02)Background Men with high serum prostate specific antigen usually undergo transrectal ultrasound-guided prostate biopsy (TRUS-biopsy). TRUS-biopsy can cause side-effects including bleeding, pain, and infection. Multi-parametric ... -
Diagnostic accuracy of whole-body MRI versus standard imaging pathways for metastatic disease in newly diagnosed colorectal cancer: the prospective Streamline C trial.
(ELSEVIER INC, 2019-07-01)BACKGROUND: Whole-body MRI (WB-MRI) could be an alternative to multimodality staging of colorectal cancer, but its diagnostic accuracy, effect on staging times, number of tests needed, cost, and effect on treatment decisions ... -
Diagnostic accuracy of whole-body MRI versus standard imaging pathways for metastatic disease in newly diagnosed non-small-cell lung cancer: the prospective Streamline L trial.
(ELSEVIER SCI LTD, 2019-06-01)BACKGROUND: Whole-body magnetic resonance imaging (WB-MRI) could be an alternative to multi-modality staging of non-small-cell lung cancer (NSCLC), but its diagnostic accuracy, effect on staging times, number of tests ... -
Diagnostic and Therapeutic Biomarkers in Glioblastoma: Current Status and Future Perspectives.
(HINDAWI LTD, 2017-01-01)Glioblastoma (GBM) is a primary neuroepithelial tumor of the central nervous system, characterized by an extremely aggressive clinical phenotype. Patients with GBM have a poor prognosis and only 3-5% of them survive for ... -
Diagnostic radiological examinations and risk of intracranial tumours in adults-findings from the Interphone Study.
(OXFORD UNIV PRESS, 2022-05-09)BACKGROUND: Exposure to high doses of ionizing radiation is among the few well-established brain tumour risk factors. We used data from the Interphone study to evaluate the effects of exposure to low-dose radiation from ... -
Diagnostic ultrasound probes: a typology and overview of technologies
(Walter de Gruyter GmbH, 2018-09-01)<jats:title>Abstract</jats:title> <jats:p>The routine clinical use of diagnostic ultrasound (US) has spread considerably worldwide in recent decades. This is due in large part to the availability of US probes ... -
Diagnostic uncertainty presented barriers to the timely management of acute thrombotic thrombocytopenic purpura in the United Kingdom between 2014 and 2019.
(WILEY, 2022-03-11)BACKGROUND: Acute thrombotic thrombocytopenic purpura (TTP) is a life-threatening emergency and plasma exchange (PEX) is the initial treatment shown to reduce acute mortality. OBJECTIVES: To compare current practice in the ... -
Diagnostic Utility of Molecular and Imaging Biomarkers in Cytological Indeterminate Thyroid Nodules.
(2018-04)Indeterminate thyroid cytology (Bethesda III and IV) corresponds to follicular-patterned benign and malignant lesions, which are particularly difficult to differentiate on cytology alone. As ~25% of these nodules harbor ... -
Dicentric Dose Estimates for Patients Undergoing Radiotherapy in the RTGene Study to Assess Blood Dosimetric Models and the New Bayesian Method for Gradient Exposure.
(RADIATION RESEARCH SOC, 2018-09-20)The RTGene study was focused on the development and validation of new transcriptional biomarkers for prediction of individual radiotherapy patient responses to ionizing radiation. In parallel, for validation purposes, this ... -
Dichloroacetate induces autophagy in colorectal cancer cells and tumours.
(NATURE PUBLISHING GROUP, 2014-07-15)BACKGROUND: Dichloroacetate (DCA) has been found to have antitumour properties. METHODS: We investigated the cellular and metabolic responses to DCA treatment and recovery in human colorectal (HT29, HCT116 WT and HCT116 ... -
Dickkopf-3 links HSF1 and YAP/TAZ signalling to control aggressive behaviours in cancer-associated fibroblasts.
(NATURE PUBLISHING GROUP, 2019-01-10)Aggressive behaviours of solid tumours are highly influenced by the tumour microenvironment. Multiple signalling pathways can affect the normal function of stromal fibroblasts in tumours, but how these events are coordinated ... -
Dietary omega 6/3 fats and aspirin govern PI3Ka-induced oncogenicity
Oncogenic mutations in PI3KCA, the gene encoding the p110a catalytic subunit of PI3K, represent one of the most frequent genetic alterations in human cancer. Although multiple inhibitors of the PI3K/AKT/mTOR pathway have ... -
Differences in Quality of Life and Toxicity for Male and Female Patients following Chemo(radiotherapy) for Bladder Cancer.
(ELSEVIER SCIENCE LONDON, 2023-02-01)AIMS: BC2001, a randomised trial of treatment for muscle-invasive bladder cancer, demonstrated no difference in health-related quality of life (HRQoL) or late toxicity between patients receiving radical radiotherapy with ... -
Differences in Signaling Patterns on PI3K Inhibition Reveal Context Specificity in KRAS-Mutant Cancers.
(AMER ASSOC CANCER RESEARCH, 2019-08-01)It is increasingly appreciated that drug response to different cancers driven by the same oncogene is different and may relate to differences in rewiring of signal transduction. We aimed to study differences in dynamic ... -
