Table 2 Perfusion defects seen in COVID-19 and non-COVID-19 pneumonias depending on the type of parenchymal lesion

From: Dual-energy CT angiography reveals high prevalence of perfusion defects unrelated to pulmonary embolism in COVID-19 lesions

  Pneumonia type Lesion types
  GGO CS OP CP TIB
Perfusion defects (n/total, %) COVID-19 3/15 (20%) 9/10 (90%) 18/22 (82%) 10/20 (50%) 0/0 (0%)
  Non-COVID-19 2/8 (25%) 19/67 (28%) 0/1 (0%) 0/1 (0%) 0/2 (0%)
  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
