摘要:
 【摘 要】 目的：评估国产便携式B超膀胱测定仪MD-6000测量膀胱容量的准确度，并探讨其在盆腔肿瘤患者分次放疗前膀胱体积监测中的临床应用价值。 方法：将气球灌定量水制作的模拟膀胱经加速器CBCT扫描后勾画测定其体积，并与实际水体积进行相关性分析，评估CBCT勾画体积的精确性；将176例成人膀胱的便携式B超仪测定值与加速器CBCT扫描后膀胱勾画测定容积值相比较，进行相关性分析，评估国产便携式B超膀胱测定仪MD-6000的测量准确度。 结果：气球灌定量水模拟膀胱经CT扫描后勾画测定体积与实际水量之间函数式为[Y=0.958 51X-14.430 8]，相关系数[R=0.999 85]，证明两者之间存在着强相关；便携式B超测定仪所测得的膀胱容量值与加速器CBCT扫描后膀胱勾画测定值之间函数式为[Y=0.855 32X-8.040 38]，相关系数[R=0.913 5]9，证明两者之间存在着强相关。 结论：利用国产便携式B超膀胱测定仪MD-6000评估膀胱体积不仅操作方便、测量速度快、准确性高、可重复性好，而且有助于盆腔肿瘤放疗患者的膀胱容量监测，维持分次放疗膀胱容量稳定，减少靶位置的移动，在盆腔肿瘤放疗中具有重要的临床应用价值。
Abstract:
 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.
