Aim of this study is to determine how accurately various measures of the PA, as viewed on HRCT, predict right heart catheterization (RHC)-confirmed pulmonary hypertension. Methods: The present study was conducted in the Department of Radiology and 200 patients were included in the study. Patients with a CT scan within 90 days of MRI and RHC were included. In order to meet inclusion criteria, a diagnostic quality CT pulmonary angiogram (CTPA) with a slice thickness of less than 5 mm was required. Results: 100 (50%) of 200 participants in our study had RHC-verified pulmonary hypertension and 25 mmHg mPAP. The pulmonary hypertension group had higher MPAD, RPAD, LPAD, and PA:Ao during both respiratory cycles than the non-hypertensive group. Non-pulmonary hypertension patients had a larger PA angle. The median MPAD in the pulmonary hypertension subgroup was 34.60 mm during inspiration and 34.65 mm during expiration. In contrast, non-pulmonary hypertension patients had a median MPAD of 30.00 mm during inspiration and 30.50 mm during expiration. The inspiratory MPAD and PA:Ao AUCs for RHC-confirmed pulmonary hypertension (Mpap ≥25 mmHg) were 0.741 and 0.750, respectively, for the entire group. The population's diagnostic traits were best when MPAD cut-offs were 32.5 mm and PA:Ao were 0.94. Conclusion: HRCT findings can aid in diagnosing pulmonary hypertension that has been verified by RHC. The sensitivity of MPAD was 29 mm, whereas the specificity of PA:Ao was 1.0. MPAD exhibited higher sensitivity in ILD compared to the overall cohort, while PA:Ao had greater specificity in COPD.
