Key result
High frame rate Doppler echocardiography provided accurate non-invasive measurements of cardiac structure and function in rats, correlating well with transit time measurements (R=0.93).
Why the study?
Does high frame rate Doppler echocardiography provide accurate measurements of cardiac structure and function compared to transit time and M-mode measurements in normal rats?
Does high frame rate Doppler echocardiography provide accurate measurements of cardiac structure and function compared to transit time and M-mode measurements in normal rats?
Effect estimate: R=0.93

Supports rat cardiac phenotyping without invasive probes; leaves open human translation pending validation.
Reidar Bjørnerheim (2001) studied Normal Wistar rats (n=14). High frame rate Doppler echocardiography vs. Ultrasound transit time measurements and M-mode echocardiography was evaluated on Accuracy of aortic flow measurements compared to ultrasound transit time (R=0.93). High frame rate Doppler echocardiography provided accurate non-invasive measurements of cardiac structure and function in rats, correlating well with transit time measurements (R=0.93).
