[Comparative CT study of the anterior cruciate ligament in direct projection and using sagittal reconstruction]

The authors present an indirect method for the visualization of the anterior crucial ligament, using the method of sagittal reconstruction. Positioning in the so-called tailor's seat is often impossible in freshly injured persons. The abdominal positioning described in this article, with external rotation of the leg, is tolerated by almost all patients. Sagittal reconstruction yields adequate information in fresh lesions and if there is an obstruction to bending. However, this method is diagnostically not as infallible as the direct visualization. The authors discuss whether additional reconstructions on different planes and with pixels of different thickness (so-called thick pixel reconstruction) may be able to contribute to improved diagnostic results in future. In addition, the authors compare their own examination results with normal and pathological findings published by other authors.
