Clinical Implementation
Value Proposition
Measurement of flow in the pulmonary artery is a well-established clinical parameter that has fundamental diagnostic, therapeutic, and prognostic implications. Cardiac Magnetic Resonance (CMR) allow accurate assessment of flow parameters. Automated pulmonary artery flow quantification would save the interpreting physician time via elimination of manual measurements, prevent detection errors, and provide structured quantitative data, which could be used in later studies or risk stratification schemes.Narrative(s)
All patients undergoing CMR examinations which include flow measurements should have automated quantification of pulmonary artery flow if data are available, which may then be automatically populated into the radiology report or a report supplement.Workflow Description
Patient receives MRI of the chest/heart. Algorithm retrieves pulmonary artery flow imaging dataset if present and may ingest additional EMR data such as age, sex, and body surface area. Algorithm executes and calculates values of net flow, flow volume, maximum flow velocity and flow gradient in the pulmonary artery. Algorithm also determines if aliasing is present. Algorithm returns all measurements, which could populate the report (possibly within a supplement containing other quantitative data). Algorithm flags abnormal values.Considerations for Dataset Development
