Lung perfusion findings on perfusion SPECT/CT imaging in non-hospitalized de-isolated patients diagnosed with mild COVID-19 infection

Abstract Background The aim of this retrospective study is to assess the incidence and type lung perfusion abnormalities in non-hospitalized patients diagnosed with mild COVID-19 infection after de-isolation. Data from 56 referred our nuclear medicine department July–December 2020 for a only SPECT/CT or ventilation were collected. Images assessed presence defects. CT component was also mosaic attenuation COVID pneumonia changes. Results Thirty-two (57.1%) cases had There 20 (35.7%) defects keeping pulmonary embolism, 17 (30.4%) associated but not due 6 (10.7%) infiltrates pneumonia. A total 24 (42.9%) on CT, 10 (17.9%) them showing pattern likely consistent shunting images. Conclusion Lung are common finding disease. They usually either parenchymal infiltrates, other causes related to, specific pathophysiology infection. value VQ imaging shown study, detecting differentiating various types abnormalities.
