Frequency and Distribution of Chest Radiographic Findings in Patients Positive for COVID-19

Abstract: StatementChest x-ray abnormalities in COVID-19 mirror those of CT, demonstrating bilateral peripheral consolidation. Chest x-ray findings have a lower sensitivity than initial RT-PCR testing (69% versus 91%, respectively). Key Results In a cohort of patients with COVID-19 infection and imaging follow-up, baseline chestx-ray had a sensitivity of 69%, compared to 91% for initial RT-PCR. Chest x-ray abnormalities preceded positive RT-PCR in 6/64 (9%) patients. Common chest x-ray findings mirror those previousl… Show more

“…imaging which is chest CT since only a small sub-sets of our patients underwent CT. No attempt to correlate CXR and CT findings of this small sub-set of patients was made but some anecdotal cases have been used in our representative figures. However the almost perfect agreement between our two independent readers support the reliability of our results also considering similar results published by Wong et al [11]. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 All rights reserved.…”

“…A los pacientes y a los médicos con una RT-PCR negativa pero que mantuvieron clínica compatible con COVID-19 se les repitió el diagnóstico mediante RT-PCR. Se consideraron signos radiológicos compatibles con COVID-19 la aparición de infiltrados periféricos en vidrio deslustrado, patrón alveolar difuso, sombreados parcheados bilaterales, patrón en empedrado, neumonía organizativa (6) .…”

“…Although chest X-rays are less sensitive than CT scans, the former may be used as a first-line approach because of their availability and ease of decontamination. Chest X-ray findings may be normal earlier in the clinical course and tend to peak 10-12 days after the onset of clinical symptoms [10]. Figure 1 represents early and latestage X-ray findings in patients with COVID-19.…”
