Clinical Feasibility of a Low-dose Computed Tomography Angiography Protocol with an Iterative Reconstruction Algorithm in Preoperative Examinations for Anterolateral Thigh Perforator Flap Surgery
Abstract: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, b… Show more
