Revisiting Perfusion in the Forgotten Right Ventricle: Artificial Intelligence-Enhanced Quantification on PET/CT.
An AI algorithm now accurately measures right heart blood flow on routine imaging, enabling earlier detection of right-sided heart failure and pulmonary hypertension.
This multicenter J Nucl Med study develops and validates an AI algorithm for quantifying right ventricular perfusion on PET/CT — a measurement previously difficult to standardize — with implications for diagnosing RV failure, pulmonary hypertension, and arrhythmia risk. The work extends AI cardiac imaging tools to the understudied right heart.
