16-MDCT of the posttraumatic pediatric elbow: optimum parameters and associated radiation dose

AJR Am J Roentgenol. 2005 Aug;185(2):516-21. doi: 10.2214/ajr.185.2.01850516.

Abstract

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.

Conclusion: 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.
