Background: In the past several years, emerging imaging techniques, such as computed tomography angiography (CTA), Doppler ultrasound, and magnetic resonance imaging (MRI), have been used for investigating the anatomy and perfusion of perforator complexes. Preoperative CTA can provide explicit information on perforator flaps, which not only helps surgeons to evaluate the optimal design of flaps with respect to the lateral circumflex femoral artery (LCFA) territory and the concomitant venous drainage pattern, but also reduces postoperative complications and secondary operation rates. Objectives: This study aimed to evaluate the clinical feasibility of a low-dose CTA protocol with adaptive statistical iterative reconstruction (ASIR) for patients scheduled for anterolateral thigh perforator flap (ALTPF) surgery. Results: The age, sex, and body mass index (BMI) were not significantly different between the three groups (P > 0.05 for all). The FOM of images in the three segments was significantly higher in group C compared to the other two groups (P < 0.001 for all). The results of subjective evaluation revealed no poor-quality images, and the Likert score did not significantly differ between the groups. Compared to group A and group B, significant reductions were observed in CTDI, DLP, and ED in group C. Conclusion: The 80-kVp protocol with ASIR not only reduced the radiation dose, but also exhibited lower performance compared to the 120-kVp protocol with FBP and the 80-kVp protocol with ASIR; it also yielded relatively satisfactory image quality.
