Does echocardiographic automatic boundary detection accurately and reproducibly measure left atrial size and function compared to conventional methods?
Automatic boundary detection provides reproducible instantaneous left atrial cavity measurements, though derived functional indices have poor reproducibility.
Clarkson et al. (1995) studied this question.
