Nonetheless, radiation concerns arise due to patients receiving a significant effective dose (ED). Thus, patient dose evaluation is critical to ensure that benefits compensate for the projected cancer risk. The current study aimed to assess abdominopelvic CT radiation exposure.</span></span></span> <span lang="en-US" style="font-size:9.0pt"><span style="font-family:Calibri"><span style="color:#1f497d"><span style="font-style:italic"><span style="font-weight:bold"><span style="language:en-US">Material and Methods</span></span></span></span></span></span><span lang="en-US" style="font-size:9.0pt"><span style="font-family:Calibri"><span style="color:#1f497d"><span style="font-weight:bold"><span style="language:en-US">:</span></span></span></span></span> <span lang="en-US" style="font-size:9.0pt"><span style="font-family:Calibri"><span style="language:en-US">A cross-sectional analytical design was conducted for 130</span></span></span> <span lang="en-US" style="font-size:9.0pt"><span style="font-family:Calibri"><span style="language:en-US">abdominopelvic CT procedures.
