EGFR mutation prediction using F18-FDG PET-CT based radiomics features in non-small cell lung cancer [PDF]
arXiv, 2023 Lung cancer is the leading cause of cancer death in the world. Accurate determination of the EGFR (epidermal growth factor receptor) mutation status is highly relevant for the proper treatment of this patients. Purpose: The aim of this study was to predict the mutational status of the EGFR in non-small cell lung cancer patients using radiomics features

The Past, Present and Future of Diagnostic Imaging in Ovarian Cancer [PDF]
, 2018 Ovarian cancers (OC) include a group of diseases with variable prognoses. While most conventional imaging techniques rely on the detection of tumour burden and distant spread to identify treatment plans, more emphasis is now being placed on screening for

Gamma-ray emission from novae related to positron annihilation: constraints on its observability posed by new experimental nuclear data [PDF]
, 1999 Classical novae emit gamma-ray radiation at 511 keV and below, with a cut-off at around (20-30) keV, related to positron annihilation and its Comptonization in the expanding envelope. This emission has been elusive up to now, because it occurs at epochs well before the maximum in optical luminosity, but it could be detected by some sensitive intrument ...

Prostate cancer and sarcoma: Challenges of synchronous malignancies
Radiology Case Reports, 2020 Synchronous primary malignancies are a rare finding which can be difficult to diagnose. We present the case of a 57-year-old patient with a high prostate specific antigen who was found to have prostate cancer on subsequent magnetic resonance imaging.

Role of integrated F-18 fluoro-deoxy-glucose positron emission tomography and computed tomography in evaluation of lung cancer [PDF]
Archive of Oncology, 2012 Lung cancer is one of the leading causes of death in the world. It is generally divided in two groups: non-small cell lung cancer (NSCLC) and small cell lung cancer (SCLC).

The Common Alzheimer's Disease Research Ontology (CADRO) for biomarker categorization
Alzheimer's &Dementia: Translational Research &Clinical Interventions, Volume 11, Issue 1, January-March 2025.Abstract Biomarkers are vital to Alzheimer's disease (AD) drug development and clinical trials, and will have an increasing role in clinical care. In this narrative review, we demonstrate the use of the National Institutes on Aging/Alzheimer's Association (NIA/AA) Common Alzheimer's Disease Research Ontology (CADRO) system for the categorization of ...
