Abstract:
Objective:To analyze the accuracy of Chongqing Kangchao Z5 B-ultrasound bladder volume measurement scanner (BS) for bladder volume measurement in pelvic tumor radiotherapy,and to explore the clinical value of bladder filling management combined with BS monitoring bladder volume in maintaining the consistency of bladder filling between treatments and reducing target location shift during pelvic radiotherapy.Methods:A total of 30 patients with pelvic tumor radiotherapy were selected and individualized bladder filling assessment was performed for each patient.Bladder filling,modeling,and CT localization were performed under the whole process management.The bladder volume was measured immediately after the CT scan was completed (recorded as BSV2),and the CT scan images were imported into the planning system to sketch the CT scan bladder volume (recorded as CTSV).The correlation and deviation between BSV2 and CTSV in 30 patients were analyzed.Individualized whole process bladder filling management was performed for 30 patients with pelvic tumor,and the bladder volume (recorded as BSV4) was measured by BS immediately after each radiotherapy.The mean value of BSV4 after all radiotherapy (recorded as BSVmean) of each patient was used for correlation analysis with CTSV,and the deviation analysis between BSV4 and CTSV after each radiotherapy was performed.Results:There was a strong correlation between BSV2 (Y) and CTSV (X) in the enrolled 30 patients.The function was Y=24.838+0.959X,and the correlation coefficient R=0.946.The mean deviation (mean±standard deviation) between BSV2 and CTSV was (4.16%±2.43%).There was also a strong correlation between BSVmean (Y) and CTSV (X) in the enrolled 30 patients during the course of treatment,with the function Y=27.115+0.936X,and the correlation coefficient R=0.986.The mean deviation (mean±standard deviation) between BSV4 and CTSV was (4.05%±2.88%).Conclusion:Chongqing Kangchao Z5 B-ultrasound bladder volume measurement scanner has high measurement accuracy and good repeatability,and can be used to monitor bladder volume in pelvic radiotherapy.Combined with bladder filling management in the whole process,it can effectively ensure the consistency of bladder filling between treatments and the stability of target location in precise radiotherapy for pelvic tumors.
