Synopsis
50 patients scheduled for instrumented posterior thoracic or lumbar fusion surgery were randomized to intraoperative CT acquisition using either a low-dose protocol or high-dose protocol. Patients were assessed for correct pedicle screw placement using the Gertzbein and the Heary classifications, as well as radiation exposure using dosimeters. Rate of correct pedicle screw placement was significan...
