Images in rows 1 and 2 are perfusion only SPECT/CT images of a 46-year-old female, 14 days post COVID-19 infection, showing a perfusion defect in the left lung (crosshair), with associated mosaic hypoattenuation on CT seen in the first two rows. Images in rows 3, 4, and 5 are VQ SPECT/CT images acquired 3 months later, confirming matching defects with little or no reduction in defect size and persistent mosaic hypoattenuation on CT
