Hierarchy of imaging-study quality

NLP if original source is: CART if original source is:
High quality TTE or TEE (1 LVEF reported) TTE or TEE
MRI
CT
Medium quality TTE or TEE (>1 LVEF reported)
Clinical documentation		 Ventriculography
Low quality (excluded) Radiology SPECT
PET

CART, Clinical Assessment and Reporting Tracking program; CT, cardiac computed tomography; LVEF, left ventricular ejection fraction; MRI, magnetic resonance imaging; NLP, natural language processing; PET, positron emission tomography; SPECT, single-photon emission computerized tomography; TEE, transesophageal echocardiogram; TTE, transthoracic echocardiogram.
