We conducted the study using a large public dataset. We tested 5 different pre-processing methods and investigated their effect on the final classification. In this article, we present the impact pre-processing can have on the results of a classification system. Thus, the implementation of AI and ML in COVID-19 and other lung diseases seems to be the desired natural progression. Artificial intelligence (AI) and ML can be used in numerous applications such as cybersecurity, pedestrian detection, telemedicine, biometrics or sports analytics. But, the use of machine learning (ML)-based methods can improve efficiency, support medics in the diagnosis of COVID-19, speed up the time to diagnosis, and lighten the already burdened health care system.Īt the same time, modern technologies have gathered more interest. However, X-ray analysis can be time-consuming and requires highly educated specialists to interpret. Moreover, CXR imaging is more widely available than CT imaging, especially in developing countries due to high equipment and maintenance costs. This imaging modality is highly available and accessible in many clinical locations, and it is considered standard equipment in most healthcare systems. In addition, patients suffering from COVID-19 can also present with abnormalities on chest X-ray images that are characteristic of infection. The RT-PCR test can detect SARS-CoV-2 ribonucleic acid (RNA) from respiratory specimens (collected through nasopharyngeal or oropharyngeal swabs). Currently, the main screening method for detecting COVID-19 infections is reverse transcriptase-polymerase chain reaction (RT-PCR) testing. Currently, people all over the world are doing their best to overcome the pandemic’s impact on the social, medical, psychologic, economic, and industrial aspects of society. It has caused societies to close, crowded streets to become deserted, pubs and clubs to be silenced, and popular meeting places to die down. By analysing the results of all these tests, the problem can be identified, and the doctor can plan a course of action with the patient to treat the condition.The occurrence of the COVID-19 pandemic in 2020 has shaken up the modern world. If the doctor is concerned by an abnormal chest X-ray, but doesn’t have enough information to make a diagnosis, they may order further tests, including a chest CT scan or a PET scan. Fractures will be quickly and easily seen in the scan as dark lines through the bone.Ī radiologist will look for clues indicating there is an abnormality and will report with the doctor who ordered the chest x-ray. Any abnormalities with the heart or surrounding it will appear as lighter or darker areas.īones: bones are the densest natural structure seen in a chest x-ray. Heart: the heart blocks radiation so will appear lightly in the scan. A doctor will assess which side of the lungs or if both sides are abnormal based on key surrounding features. Lungs: the whiter the lungs appear on the scan, the more dense they will be the darker they are, the less dense. What does an abnormal chest x-ray look like?
pneumonia (unusual white or hazy shadow on the normally dark lungs on the X-ray can indicate this).position of pacemaker, defibrillator, or catheterĪn abnormal chest X-ray can be caused by a number of conditions.Other reasons a chest x-ray may be ordered is to reveal: Some doctors specialise in dealing with abnormalities in chest X-ray results, and may order follow-up tests to determine the cause.Ī doctor may order a chest x-ray if a patient is presenting with symptoms such as: This is usually indicative of a problem, and could be immediately obvious, such as a broken or fractured rib, or could simply be a shadow that needs further investigation. If the X-ray images show abnormalities, this means that there is something unusual on the image of the chest. In this way, doctors can examine the heart, lungs, bones, and blood vessels. What does an abnormal chest x-ray look like?Ī chest X-ray is an imaging test that utilises low doses of radiation in short blasts to create images of the inside of a patient’s chest.
