Weight bearing CT scans are helping us understand pediatric foot deformities better than ever before.…
A study published in Foot and Ankle Surgery compared three common angle measurements of the foot taken from non-weight bearing CT, weight bearing digital radiographs, and weight bearing pedCAT scans. The study concludes, “The angles differed between radiographs, CT and pedCAT, indicating that only pedCAT is able to detect the correct angles… pedCAT prevents inaccuracies of projection and foot orientation in contrast to radiographs due to the 3D dataset which is principally independent from projection and foot orientation.”
The study also found the average image acquisition time for the pedCAT (average 270 seconds) was 70 percent faster than with radiographs and 35 percent faster than with CT.
The study was authored by Martinus Richter, Bernd Seidl, Zech Stefan, and Sarah Hahn.
