Resumen
VELASCO JIMENEZ, Héctor Manuel et al. Role of chest CT in SARS-CoV-2 pneumonia patients. Experience of Hospital Angeles Lomas. Acta méd. Grupo Ángeles [online]. 2020, vol.18, n.4, pp.390-394. Epub 06-Jun-2022. ISSN 1870-7203. https://doi.org/10.35366/97265.
Objective:
To clarify the role of CT in the management of patients with SARS-CoV-2 pneumonia and to generate standardized radiological reports.
Material and methods:
108 simple chest tomography scans were evaluated, of patients with suspected SARS-CoV-2 pneumonia who also underwent RT-PCR.
Results:
68 patients had tomographic findings suggestive of SARS-CoV-2 pneumonia (consensus of the RSNA and CO-RADS), of which 51 had additionally positive RT-PCR test. The other group of 40 patients had normal or negative tomographies, with 6 positive results for RT-PCR respectively. The sensitivity of the CT in our study was 89%, the specificity of 66% with an LR (+) of 2.61 and LR (-) of 0.16.
Conclusion:
CT lacks specificity to be considered a diagnostic test, however its use as a screening tool is justified in certain clinical contexts. A potential virtue of CT is its utility as a tool in prognosis and therefore patient management.
