16-MDCT of the posttraumatic pediatric elbow: optimum parameters and associated radiation dose.
OBJECTIVE
Our objective was to investigate a low-radiation-dose protocol for 16-MDCT of the posttraumatic pediatric elbow using z-axis automatic tube-current modulation, based on optimum scanning parameters determined in a porcine fracture model, and to report the radiation dose from this technique in nine children with acute elbow trauma.


CONCLUSIONS
For the posttraumatic pediatric elbow, 16-MDCT using z-axis automatic tube-current modulation was optimal at 100 kVp with a noise index of 20 and a minimum amperage of 25 mA.
