For pneumonia. Methods and Materials: A retrospective, cross-sectional study was conducted in Damascus Hospital (Al-Mujtahid), by referring to the records and files of Corona patients admitted to the hospital during the peak of the first Corona infection in the Syrian Arab Republic during a period of 5 months from the first month of 2020 AD until the fifth month in The second peak in 2021 AD, from month 5 to month 8. The study included 225 patients out of 286 patients who met the exclusion and inclusion criteria. Results The percentage of infiltrates on plain chest CT, segmental infiltrates, and hemipectoral shadow were 8.7%, 26.2%, and 2.09%, respectively. Radiological signs on CT in our study: ground glass densities in 95%, pulmonary condensation syndrome in 86%. Tile sign 75%, pulmonary caverns 5%, pulmonary nodules forming in the center of the lobule 7%, tree bud view 9%, thickening of interlobular occlusions 16%, perilobular densities 25%, reticular infiltrates 16%, phlegmon nodular hyperplasia 20%, pleural effusion 3%. Conclusion The COVID-19 pandemic has dramatically changed human routines and the healthcare sector, and it is essential for radiologists to be aware of the basic clinical and radiological aspects of COVID-19. Pulmonology COVID-19 radiological evaluation complications evaluation Introduction Coronavirus is a disease caused by a virus called Severe Acute Respiratory Syndrome Virus (SARS-COV-2), which is a global pandemic that particularly affects the respiratory system. Coronaviruses consist of a large family of coronaviruses, seven of which are known to cause disease. For humans, and over time some coronaviruses that normally infect animals have evolved to infect humans. SARS-Cov-2 is likely one of these viruses, and it is assumed that it originated in animals and seafood. More than 8,000 people were infected with the coronavirus, and nearly 800 of them died. Due to the disease (the death rate is about 10%), before it was controlled in 2003 AD, but the Corona virus continued to appear in sporadic cases, and in late February 2022 AD, a total of 2,585 laboratory-confirmed cases of respiratory distress syndrome were reported worldwide (890 One MERS-related death, case-fatality ratio, 34.4%. [ 1 – 2 ] Computed tomography plays an important role in diagnosing and following up cases of COVID-19 infection and its complications, as current guidelines indicate the use of high-resolution computed tomography in patients with COVID-19 thanks to its high accuracy in detecting lung changes in viral pneumonia, and to exclude other causes of pneumonia. [ 3 ] Methods and Material A practical study of the retrospective, cross-sectional type was conducted in Damascus Hospital (Al-Mujtahid), by referring to the records and files of Corona patients admitted to the hospital during the peak of the first Corona infection in the Syrian Arab Republic during a period of 5 months from the first month of 2020 AD until the fifth month and at the second peak in 2021 AD. From the fifth month until the eighth month patients The study included 225 patients out of 286 who met the exclusion and inclusion criteria inclusion criteria Patients admitted in the isolation department and the intensive care unit, and x-ray images in the archives of the Radiology Department in Damascus Hospital. Exclusion criteria Patients in intensive care who developed poor general condition and low oxygen values and who were not subjected to a CT scan were excluded due to the difficulty of transporting them to the CT room. method used The international standards of the American College Radiology (ACR) were used, and the literature of the Chinese Society and the Brazilian Radiological Society was adopted. According to references and sources, the sensitivity of simple images with tomography globally exceeds 97%, while the accuracy of simple images does not exceed 20–33%, and according to the study (53 (published in Radiology magazine in 2020 AD. The data was transcribed from the forms into an Excel file, simple statistics were conducted, the results were summarized and explained with tables and charts, a statistics program was used and descriptive statistics were reviewed based on percentages and Spss-28 charts in addition to measures of central tendency (Arithmetic mean and standard deviation) Relying on the CO-RADs classification and global standard: CO-RADS-1: There are no positive radiological manifestations or signs and the CT scan is normal or no inflammatory or septic manifestations are observed. CO-RADS-2: Low (mild) infection, radiological disorders are from infections, and any infectious condition other than Corona may be seen CO-RADS-3: Moderate involvement and unclear radiographic signs CO-RADS-4: High incidence of radiological manifestations and strongly suggest the presence of Corona CO-RADS-5: Very severe, typical manifestation of coronavirus infection Ethical considerations Ethical approval was obtained from the Institutional Review Board (IRB) Faculty of Medicine, Syrian Private University, Results In our study, it was found that the rate of presence of infiltrates on a plain chest X-ray was 8.7%, the rate of presence of segmental infiltrates was 26.2%, and the rate of presence of a shadowy hemi-chest was 2.09%. It was found that the radiological signs in CT in our study were: ground-glass densities by 95%, pulmonary condensation syndrome by 86%. %, paved tile signs 75%, pulmonary caverns 5%, pulmonary nodules forming in the center of the lobule 7%, tree bud view 9%, thickening of interlobular occlusions 16%, perilobular densities 25%, retinal infiltrates 16%, phlegmon nodular hyperplasia. 20%, pleural effusions 3%, and the rate of appearance of radiological signs with the onset of clinical symptoms: ground glass densities after 12–13 days at a rate of 98%, retinal infiltrates after 14 days at a rate of 92%, that in most cases studied by CT the sample was selected without injection. Contrast material to search for the radiological signs that are often prescribed to search for the appearance of crushed glass, paved tile densities, and other signs, and the indication for injections to search for Covid complications, especially pulmonary embolus. These cases were excluded. The radiographic signs that included the sample were analyzed during the period of stay in the hospital: 0–4 Days: Ground glass view, 5–8 days: Ground glass view with paved tiles, 9–13 days: Paved tiles view, After 14 days: Regression stage of radiographic marks in tomography In the early stages, glass view dominates: In the late stage, paved tiles view dominates The cases were classified into moderate, severe and diffuse type: moderate type: 5% focal macular pattern, severe type: 30% comprehensive spread of densities, diffuse type: 65% white lung appearance and lack of normal parenchyma, and the lesions are distributed according to the lobes (pulmonary and most cases are bilateral ): Right and left upper pulmonary lobe 25%, right and left lower pulmonary lobe 25%, right and left upper pulmonary lobe 13%, right and left upper pulmonary lobe 17%, middle lobe and right lower pulmonary lobe 10%, middle lobe and right upper pulmonary lobe 10%, complications of coronavirus infection were evaluated and evaluated radiographically by CT with clinical correlation (thoracic pulmonary complications): pulmonary fibrosis 45%, bacterial pneumonia 5%, pleural effusion 3%, pericardial effusion 2%, pulmonary embolism 20%, unfollowed cases ( You left the hospital at their own risk or when symptoms disappeared) 25%. Discussion It was found that the accuracy of simple x-rays was 10%, and the positivity of simple x-rays was 68% compared to scientific studies, where it was shown that the accuracy of simple x-rays does not exceed 33%, which is that all patients arrived in advanced cases and showed symptoms and the images were positive. CT analysis globally • Ground glass view 88% • Bilateral lesion 88% • Diffusion and back distribution 80% • Inclusion of more than one lung lobe 79% • Peripheral spread is only 76%. • Pulmonary condensation syndrome 32% There are several recommendations that were concluded through our study of Corona cases admitted and followed up in Al-Mujtahid Hospital, which are: 1. The need to educate people well about this disease and increase education and awareness about the pandemic 2. Do not rely entirely on the PCR swab 3. The specific radiological examination is a high-resolution multi-slice CT and plain radiographs are not completely reliable 4. Correlating clinical symptoms with radiological findings 5. We contacted the supervising doctors to evaluate the cases radiologically, and we reached the possibility of conducting a lung echo to evaluate the Corona cases and follow up on development and recovery. It is an easy and useful radiological investigation and the possibility of conducting it in isolation and intensive care units in the presence of trained radiologists. The goal is to reduce the exposure of Corona patients to radiation and reduce patient contact. With the neighbors, there remains the possibility of convincing radiologists with this easy and useful examination, which is applied globally and approved by radiological treatment bodies. Conclusion The COVID-19 pandemic has dramatically changed human routines and the healthcare sector, and it is essential for radiologists to be aware of the basic clinical and radiological aspects of COVID-19, and also to be aware of: following guidelines for ordering and using imaging methods, following basic measures to protect patients and professionals.
