Does a multiplanar transesophageal ultrasonic imaging system accurately measure ventricular volume in vitro?
Effect estimate: correlation coefficient 0.992
A novel multiplanar transesophageal ultrasonic imaging system demonstrates high accuracy for measuring ventricular volume in vitro.
Martin et al. (1990) studied this question. Multiplanar transesophageal ultrasonic imaging system vs. Known volume required to fill balloons and excised hearts was evaluated on Volume measurement accuracy (correlation coefficient 0.992). A multiplanar transesophageal ultrasonic imaging system accurately measured the volume of water-filled balloons and excised hearts in vitro (correlation coefficient 0.992, standard error 8 mL).
