ABSTRACT
Objective:
To investigate the difference of accuracy between magnetic induction Freehand-3D ultrasound and two-dimensional ultrasound in measuring the volume of thyroid model.Methods:
Forty thyroid models were established using porcine liver, and the Archimedes procedure was set as gold standard in the measurement of the volume of each model. The accuracy of measurement of the porcine thyroid model volume between two-dimensional ultrasound and magnetic induction Freehand-3D ultrasound were compared.Results:
There were no significant differences in the accuracy of measurements of thyroid model volume among two-dimensional ultrasound, magnetic induction Freehand-3D ultrasound and Archimedes procedure (all P>0.05). Compared with the Archimedes procedure, magnetic induction Freehand-3D ultrasonic method showed higher correlation coefficient of the measurement of thyroid model volume ( r=0.998). Bland-Altman analysis showed the lower measure error with a relative error of 3.42% and range of -9.57% to 12.07%. And the limits of agreement were (-1.253, 0.999) in the magnetic induction Freehand-3D ultrasonic measurement.Conclusions:
Compared with two-dimensional ultrasound, the magnetic induction Freehand-3D ultrasound show higher accuracy in the measurement of the volume of the thyroid model.
