Comparison study of portable bladder scanner versus cone‐beam <scp>CT</scp> scan for measuring bladder volumes in post‐prostatectomy patients undergoing radiotherapy

Abstract

The BS produces bladder volume readings of an average 19.7% difference from CT-V or CBCT-V and can potentially be used to screen for large interfraction bladder volume variations in radiotherapy to prostatic bed. The observed interfraction bladder volume variation suggests the need to improve bladder volume consistency. Incorporating the BS into practice is feasible.
