Cardiac Magnetic Resonance in Pulmonary Hypertension-an Update

Area of Science:

• Cardiology
• Radiology
• Medical Imaging

Background:

• Pulmonary hypertension (PH) presents diagnostic and prognostic challenges.
• Cardiac magnetic resonance (CMR) has emerged as a key imaging modality in PH management.

Purpose of the Study:

• To review recent advancements in CMR for pulmonary hypertension over the past three years.
• To highlight CMR applications in diagnosis, prognosis, 4D flow, strain analysis, T1 mapping, and machine learning.

Main Methods:

• Review of recent literature and studies on CMR in pulmonary hypertension.
• Analysis of established and emerging CMR techniques.

Main Results:

• CMR volumetric and functional metrics are established prognostic markers in PH.
• CMR is increasingly used for treatment response assessment and risk stratification.
• Emerging techniques like myocardial T1 mapping and strain analysis show potential for early dysfunction detection and mortality prediction.
• Machine learning offers future possibilities for automation and accuracy.

Conclusions:

• Recent large studies affirm CMR's diagnostic and prognostic value in PH.
• CMR is increasingly utilized as a clinical endpoint in PH therapy trials.
• Machine learning in CMR shows promise for improving accuracy and identifying PH imaging features.
