PET/CT to Evaluate and Monitor Post-COVID-19 Lung Disease (IMAGE)
Caption
A 71-year-old male was diagnosed with COVID-19 in October 2020. He was treated and dis-charged from the hospital. He was readmitted to the hospital for respiratory failure in January 2021. He underwent 18F-FDG PET/CT. (A) MIP whole-body image and axial fused PET/CT show FDG-avid (SUV max – 12.7) consolidation in the right lung (red arrow). Non-tracer-avid changes are noted in both lungs on CT. FDG-avid mediastinal lymph nodes (SUV max – 4.4) (yellow arrow) were also noted. The patient was given steroids and Pirfenidone for two months. He showed significant improvement in symptoms with no O2 requirement. (B) Follow-up PET/CT reveals complete resolution of the lung lesion and non-avid residual fibrotic changes in both lungs (red arrow). Mediastinal lymph nodes also show a decrease in avidity (SUV max – 2.5).
