RV/LV Uptake Ratio Among Patients with Abnormal and Normal Estimated Systolic Pulmonary Artery Pressures
| Parameter | Significant elevation (estimated PAP ≥ 40 mm Hg) | No significant elevation (estimated PAP < 40 mm Hg) | P |
| RV/LV uptake ratio (non–attenuation-corrected) | 0.43 ± 0.12 | 0.32 ± 0.05 | 0.002 |
| RV/LV uptake ratio (attenuation-corrected) | 0.5 ± 0.09 | 0.45 ± 0.11 | 0.2 |
PAP = pulmonary artery pressure.
