- Abstract: Objective To evaluate the accuracy of the domestic portable B-mode ultrasound bladder scanner MD-6000 for measuring the bladder volume, and explore the clinical application value of bladder scanner MD-6000 in monitoring the bladder volume of patients before fractional radiotherapy for pelvic tumor. Methods The bladder phantom which was established with a balloon filled with mensurable water was scanned by cone-beam computed tomography (CBCT), and then we draw the outline of the bladder phantom on the CT images and calculated the bladder phantom volume. The correlation analysis between the delineated bladder phantom volume and the actual water volume was performed for assessing the accuracy of delineated volume based on CBCT. The bladder volume of 176 adult patients were obtained with the CBCT scan examination and bladder scanner MD-6000, separately, and a correlation analysis was performed for the obtained bladder volumes to assess the accuracy of bladder volume measured with bladder scanner MD-6000. Results A strong correlations was found not only between the delineated bladder phantom volume based on CT and the actual water volume (Y=0.958 51X-14.430 8，[R=0.999 85)], but also between bladder volume delineated by CBCT and those measured with bladder scanner MD-6000 (Y=0.855 32X-8.040 38, [R=0.913 59)]. Conclusion Using the domestic portable B-mode ultrasound bladder scanner MD-6000 for evaluating the bladder volume has obvious advantages in easy operation, fast measurement speed, high accuracy and high repeatability. Moreover, bladder scanner MD-6000 is also conducive to monitor the bladder volume of patients with pelvic tumor, maintain the stabilization of the bladder volume and reduce the target organ movement during the fractional radiotherapy. The bladder scanner MD-6000 has a high value of clinical application in the radiotherapy for pelvic tumor.
