Abstract: Objective To evaluate the accuracy of the latest BladderScan BVI9400 on measuring bladder volume. Methods Two bladder phantoms were selected for investigating the accuracy of BVI9400. 341 patients with the iU22 ultrasound examinations were fol owed by BVI 9400. The difference and correlation between BVI9400 and iU22 were contrastively analyzed. Results The relative difference between results from BVI9400 and phantom volume was 2.5% and 1.36%. There was a strong correlation for patients between BVI9400 and iU22 (R=0.96, P<0.001). The relative difference between BVI9400 and iU22 decreased with the increasing of bladder volume and had no significant difference with patient’s gender (P>0.1). Conclusion BladderScan BVI9400 had the ability of high accuracy and good stability of measured data. In view of quick and conveniences, BVI9400 could be as auxiliary equipment on pelvic tumor to evaluate whether the bladder volume during fractional radiotherapy was consistency with that during CT positioning.
