Andrew BY, et al. - In the development of an automated renal resistive index (RRI)-estimating algorithm with equivalent reliability and reproducibility to human experts, researchers evaluated the utility of computer vision technology as an approach. Study participants included adult cardiac surgery patients from 7/1/2013 to 7/10/2014 with intraoperative transesophageal echocardiography-determined renal blood flow measurements. To develop an algorithm for RRI estimation from automatically processed intraoperative renal Doppler waveforms, findings corroborated the value of computer vision technology. Results demonstrated that this simple-to-use and efficient tool further adds to the clinical and research value of RRI.
