While handheld Doppler (HHD) is commonly used, newer modalities like infra\u2010red (IR) thermography and indocyanine green (ICG) angiography may offer greater accuracy and precision. We aimed to compare the diagnostic accuracy of HHD, IR thermography, and ICG angiography in identifying perforators in the anterolateral thigh (ALT) flap.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>This was a single\u2010centre, three\u2010arm parallel randomized controlled trial conducted from May 2023 to April 2025 in the Department of Burns and Plastic Surgery at a tertiary care center. Sixty patients undergoing ALT flap reconstruction were randomized (1:1:1) to HHD, IR thermography, or ICG angiography groups. The primary outcome was the diagnostic accuracy of each modality in perforator localization (defined as spatial concordance with intra\u2010operative location). Secondary outcomes included flap complications and duration of flap harvest. Data were analyzed using ANOVA and chi\u2010square tests.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Oncological resection was the most common indication for flap surgery (53.3%), and the head and neck region was the commonest site of reconstruction. ICG angiography demonstrated the highest diagnostic accuracy (85%), sensitivity (94.4%), and positive predictive value (89.47%) compared to IR thermography (50%, 100%, and 50%) and HHD (15%, 75%, and 15.79%) (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009&lt;\u20090.0001).
