| General note | Coronavirus emerged as a deadly disease in 2019 killing almost 6.25 million people, with<br/>its variants still being discovered. For timely medical treatment it is necessary to<br/>accurately and rapidly diagnose the disease. The main test used for diagnosis was “The<br/>Reverse Transcription Polymerase Chain Reaction (RT-PCR)” but due to limited<br/>availability of RT-PCR equipment at the time of outbreak, alternative methods were used<br/>to mitigate the damage. One of them was the computed tomography (CT) scans, a noninvasive imaging approach. Utilizing this CT data, deep learning (DL) models were<br/>developed to expedite the diagnostic procedure. Due to privacy concerns, the original CT<br/>scans were not shared with the public which caused hindrance in the research and<br/>development of accurate DL methods. Hence, datasets were made from secondary<br/>sources, either by extracting images from preprints or saving images in any other format<br/>than DICOM, which generated low resolution images. To address this issue, preprocessing techniques were applied to generate better results of the DL models. The pixel<br/>intensities in images are normalized such that they lie in the range of the actual values of<br/>a CT scan in the Hounsfield unit scale and then given as an input to the model. Diagnostic<br/>performance was assessed by F1-score (84%), AUC (94%) and Accuracy (81%), which<br/>is better than the performance achieved without pre-processing. This study proves that<br/>enhancing the image quality, through pre-processing techniques, can improve the results<br/>when good quality data is unavailable and accurate models can be made for detecting<br/>any disease at the time of the outbreak. |
