PurposeTo develop and validate a CT-based radiomics signature for the prognosis of loco-regional tumour control (LRC) in patients with locally advanced head neck squamous cell carcinoma (HNSCC) treated by primary radiochemotherapy (RCTx) based on retrospective data from 6 partner sites German Cancer Consortium - Radiation Oncology Group (DKTK-ROG).Material methodsPre-treatment CT images 318 HNS...
Abstract Background Limited data was available for rapid and accurate detection of COVID-19 using CT-based machine learning model. This study aimed to investigate the value chest CT radiomics diagnosing pneumonia compared with clinical model reporting system (CO-RADS), develop an open-source diagnostic tool constructed Methods enrolled 115 laboratory-confirmed 435 non-COVID-19 patients (trainin...
Background With the continuous development of medical imaging informatics technology, radiomics has become a new and evolving field in applications. Radiomics aims to be an aid support clinical decision making by extracting quantitative features from images very wide range The purpose this study was perform bibliometric visual analysis scientific results research trends application glioma. Meth...
Background: The nuclear grading of ductal carcinoma in situ (DCIS) affects its clinical risk. aim this study was to investigate the possibility predicting DCIS, by magnetic resonance imaging (MRI)-based radiomics features. And develop a nomogram combining features and MRI semantic explore potential role radiomic assessment DCIS grading.
PURPOSE Many radiomics features were originally developed for non-medical imaging applications and therefore original assumptions may need to be reexamined. In this study, we investigated the impact of slice thickness and pixel spacing (or pixel size) on radiomics features extracted from Computed Tomography (CT) phantom images acquired with different scanners as well as different acquisition an...
