Automated right ventricle-to-left ventricle diameter ratio predicts ICU stay for acute pulmonary embolism on CTPA examinations in the emergency department

A reproducible and reliable automated tool to measure right ventricle-to-left ventricle diameter ratio (RV/LV) in acute pulmonary embolism (PE) examinations on computed tomography pulmonary angiography (CTPA) can suggest right ventricle (RV) enlargement, however the relationship to outcomes has not been investigated. The purpose of this study was to assess the relationship between an automated RV/LV ratio determined by an artificial intelligence (AI) algorithm, on a set of examinations deemed positive for acute PE by an AI algorithm on CTPA studies in the emergency department (ED) and various clinical parameters in predicting mortality and outcomes.
