  1. The main lesion exhibiting a perfusion defect in PD + patients or the most represented lesion type in PD- patients were recorded
  2. GGO: ground glass opacity; CS: consolidation; OP: organizing pneumonia’s suggestive features; CP: crazy-paving; TIB: tree-in-bud; PD + : presence of a perfusion defect; PD-: absence of perfusion defect
