Value Proposition

The measurement of left ventricular (LV) function is a well-established clinical parameter that has fundamental diagnostic, therapeutic, and prognostic implications. Cardiac CT angiography (CCTA) and cardiac magnetic resonance (CMR) allow for accurate LV morphological and functional assessment. Automated LV function quantification would save the interpreting physician time by eliminating manual measurements, preventing detection errors, and providing structured quantitative data, which could then be used in later studies or risk-stratification schemes.

Narrative(s)

All patients undergoing CCTA or CMR examinations should have automated quantification of LV function if data are available, which may then be automatically populated into the radiology report or a report supplement.

Workflow Description

A patient receives ECG-synchronized CCTA of the heart. An algorithm retrieves the imaging data set and may also ingest other electronic medical records (EMR) data such as age, sex, and body surface area (BSA). The algorithm calculates the absolute LV myocardial mass and BSA-indexed LV myocardial mass.
