Figures & data
Figure 1. CTPA (A) and P-SPECT/CT (B) of Case 1. (A) CTPA of pulmonary artery, main, lobar and segmental branches without visible defects of filling. In the area of left lung lingula parenchyma consolidation and filling defect in the level of subsegmental branches. Small pleural effusion on the left. (B) Perfusion SPECT/CT in the left lung showing perfusion defect in lung lingula with parenchyma consolidation. Small pleural effusion. In the right lung hypoperfusion defects in small branches in lower lobe.
