The original version of this article, published on 25 November 2020, unfortunately contained a mistake. The following correction has therefore been made in the original: The information that Gabriel Keller and Saif Afat share the first authorship was missing. The original article has been corrected.

The article “Diagnostic accuracy of ultra-low-dose CT for torsion measurement of the lower limb”, written by Keller, G., Afat, S., Ahrend, MD. and Springer, F., was originally published Online First without Open Access. After publication in volume 31, issue 6, page 3574–3581 the author decided to opt for Open Choice and to make the article an Open Access publication.
