Ontology highlight
ABSTRACT: Background
Artificial intelligence (AI) could improve accuracy and reproducibility of echocardiographic measurements in dogs.Hypothesis
A neural network can be trained to measure echocardiographic left ventricular (LV) linear dimensions in dogs.Animals
Training dataset: 1398 frames from 461 canine echocardiograms from a single specialist center.Validation
50 additional echocardiograms from the same center.Methods
Training dataset: a right parasternal 4-chamber long axis frame from each study, labeled by 1 of 18 echocardiographers, marking anterior and posterior points of the septum and free wall.Validation dataset
End-diastolic and end-systolic frames from 50 studies, annotated twice (blindly) by 13 experts, producing 26 measurements of each site from each frame. The neural network also made these measurements. We quantified its accuracy as the deviation from the expert consensus, using the individual-expert deviation from consensus as context for acceptable variation. The deviation of the AI measurement away from the expert consensus was assessed on each individual frame and compared with the root-mean-square-variation of the individual expert opinions away from that consensus.Results
For the septum in end-diastole, individual expert opinions deviated by 0.12 cm from the consensus, while the AI deviated by 0.11 cm (P = .61). For LVD, the corresponding values were 0.20 cm for experts and 0.13 cm for AI (P = .65); for the free wall, experts 0.20 cm, AI 0.13 cm (P < .01). In end-systole, there were no differences between individual expert and AI performances.Conclusions and clinical importance
An artificial intelligence network can be trained to adequately measure linear LV dimensions, with performance indistinguishable from that of experts.
