To highlight the new data given in Pulmonary Hypertension (PH) 2022 guideline and assess the differences of radiological approach from the old version.

Pulmonary hypertension (PH) is a heterogeneous disease driven most often by pathogenic remodeling of distal pulmonary arterioles or a congestive (functional) vasculopathy resulting from pulmonary venous hypertension. (1) The latest 2022 ESC/ERS Guidelines divides PH into 5 categories:1- Pulmonary arterial hypertension2- PH associated with left heart disease3- PH associated with lung diseases and/or hypoxia4- Chronic thrombo-embolic pulmonary hypertension5- Pulmonary hypertension with unclear and/or multifactorial mechanisms. European Society of Cardiology (ESC) and European Respiratory Society (ERS) has published a new guideline on PHT at August 2022....

Right heart catheterization is the gold standard for PH diagnosis but radiologic modalities (Ultrasound, CT, MRI, DSA) are complementary tools for both diagnosis and classification.In the new guideline; PA-to-aorta ratio cut-off level changed from 1 to 0.9 on Chest computed tomography (CT) . A combination of three parameters (PA diameter ≥30 mm, RVOT wall thickness ≥6 mm and septal deviation ≥140°) was described and defined as highly predictive of PH (Table. 1). CT is also described as a useful tool for determination of parenchymal lung...

ESC-ERS 2022 guideline adds new approaches and suggestions for diagnosis and screening of PH. Radiologic modalities (USG, MR, CT, DSA) are helpful for detecting underlying condition, classification and screening.
