Abstract

The coronavirus disease 2019 (COVID-19) pandemic has triggered a global health crisis and placed unprecedented strain on healthcare systems, particularly in resource-limited settings where access to RT-PCR testing is often restricted. Alternative diagnostic strategies are therefore critical. Chest X-rays, when integrated with artificial intelligence (AI), offers a promising approach for COVID-19 detection. The aim of this study was to develop an AI-assisted diagnostic model that combines chest X-ray images and clinical data to generate a COVID-19 Risk Index (CORI) Score and to implement a deep learning model based on ResNet architecture. Between April 2020 and July 2021, a multicenter cohort study was conducted across three hospitals in Jakarta, Indonesia, involving 367 participants categorized into three groups: 100 COVID-19 positive, 100 with non-COVID-19 pneumonia, and 100 healthy individuals. Clinical parameters (e.g., fever, cough, oxygen saturation) and laboratory findings (e.g., D-dimer and C-reactive protein levels) were collected alongside chest X-ray images. Both the CORI Score and the ResNet model were trained using this integrated dataset. During internal validation, the ResNet model achieved 91% accuracy, 94% sensitivity, and 92% specificity. In external validation, it correctly identified 82 of 100 COVID-19 cases. The combined use of imaging, clinical, and laboratory data yielded an area under the ROC curve of 0.98 and a sensitivity exceeding 95%. The CORI Score demonstrated strong diagnostic performance, with 96.6% accuracy, 98% sensitivity, 95.4% specificity, a 99.5% negative predictive value, and a 91.1% positive predictive value. Despite limitations—including retrospective data collection, inter-hospital variability, and limited external validation—the ResNet-based AI model and the CORI Score show substantial promise as diagnostic tools for COVID-19, with performance comparable to that of experienced thoracic radiologists in Indonesia.

Abstract

Background: Thalassemia is a hereditary hemolytic anemia disorder. Periodic transfusion for thalassemia patients may lead iron deposit in pituitary gland and induce hypogonadotropic hypogonadism. MRI examination has been started to be used for measurement of iron level in pituitary gland. Method: This study uses cross sectional method. MRI T2 and T2* relaxometry value and SIRT2* of pituitary gland was correlated with FSH and LH level in patients with major thalassemia. This study involves 28 subjects and conducted from December 2016 to March 2017. Result: There is correlation between relaxometry values of coronal slice T2 pituitary with FSH and LH level. There is also a correlation between pituitary SIRT2* value with LH level. Conclusion: Relaxometry value of coronal slice T2 pituitary and pituitary SIRT2* value may be use as reference for iron deposit on pituitary gland as well as to monitor chelating therapy in major thalassemia â patients.
