Senior radiologists assessed objective image quality using parameters such as noise, signal-to-noise ratio (SNR), and contrast-to-noise ratio (CNR). The influence of subjective image quality and its impact on treatment plans were evaluated using a 5-point Likert scale, with scores of 3 or higher indicating acceptable image quality and adherence to treatment plan requirements. Dose length product (DLP) (mGy</span><span lang="en-US" style="font-family:Calibri"><span style="language:en-US">&times;</span></span><span lang="en-US" style="language:en-US">cm) was automatically recorded by the scanner software, DLP&times;k. </span><span lang="en-US" style="font-family:Calibri"><span style="color:#1f497d"><span style="font-style:italic"><span style="font-weight:bold"><span style="language:en-US">Results: </span></span></span></span></span><span lang="en-US" style="language:en-US">Objective image quality with DLA-CT was found to be inferior to that obtained with SD-CT (P<0.001). No significant differences were noted in subjective image quality scores between the two groups (P =0.60). Additionally, both subjective image quality scores and the effect of image quality on treatment decisions were scored at 3 or higher. The ED was significantly reduced by 48.83% in the DLA-CT group compared to the SD-CT group (21.42&plusmn;2.62 &micro;Sv and 10.96&plusmn;1.12 &micro;Sv, respectively, P=0.001). </span><span lang="en-US" style="font-family:Calibri"><span style="color:#1f497d"><span style="font-style:italic"><span style="font-weight:bold"><span style="language:en-US">Conclusion: </span></span></span></span></span><span lang="en-US" style="language:en-US">DLA-CT proves effective in the management of ankle trauma, significantly reducing ED while meeting clinical diagnostic and treatment standards.</span></span></span></span></span></span></span></div> Deep learning algorithm, ankle fracture, computer tomography, low radiation dose. 813 817 http://ijrr.com/browse.php?a_code=A-10-1-1400&slc_lang=en&sid=1 M.
