Bottom Line: Multiple PISA measurements were compared to multiple AQURO measurements in twenty patients with MR.Compared with PISA, it also reduces the analysis time allowing analysis and averaging of data from significantly more beats, improving the consistency of EROA quantification.AQURO, being fully automated, is a simple, effective enhancement for EROA quantification using standard echocardiographic equipment.

Within patient variability (SD) of EROA. Variability using AQURO is lower than variability using conventional PISA. PISA has separate values for between observer variability and (for each observer) within-observer variability.

f0030: Within patient variability (SD) of EROA. Variability using AQURO is lower than variability using conventional PISA. PISA has separate values for between observer variability and (for each observer) within-observer variability.

Mentions: Fig. 6 shows the variability between successive image sets for conventional PISA and AQURO. Because PISA requires an observer, it has separate values for between observer variability and (for each observer) within-observer variability.
