Results A total of 208 patients completed the study, including 69 with CTEPH confirmed by pulmonary angiography. Planar V/Q, V/Q-SPECT, and Q-LDCT were all highly effective for diagnosing CTEPH, with no significant differences in sensitivity or specificity observed among the three techniques (Planar V/Q [sensitivity/specificity] 94.20%/92.81%; V/Q-SPECT 97.10%/91.37%, Q-LCDT 95.65%/90.65%). However, V/Q-SPECT was significantly more sensitive (V/Q-SPECT 79.21%; Planar V/Q 75.84%, P = 0.012; Q-LDCT 74.91%, p less then 0.001), and Planar
