A novel computed tomography angiography technique: guided preoperative localization and design of anterolateral thigh perforator flap

Key points Sharp convolution kernel combined with ADMIRE iterative reconstruction improves the imaging efficacy. 80 kV tube voltage with high flow contrast agent ensures the perforator enhancement. Cinematic rendering reconstruction model facilitates the visualization of perforator anatomic variations. Preoperative CTA mapping contributes to the localization and design of the ALTP flap
