Letter to the Editor

Sir,

We read with interest the article from Dr. Parra and colleagues [1] published online 2010 March 4.

The authors are to be congratulated on their efforts in the development of an imaging guidance technique with the intention to reduce the use of ionizing radiation in children [2]. However, the authors’ routine use of CT of the temporomandibular joints following needle placement exposes children to ionizing radiation and makes their technique less desirable than US alone or interventional MRI.

Not least for this fact, the authors discuss interventional MRI as a co-existing technique for temporomandibular joint injections in children. We were, however, surprised about the omission of the citation reporting the technique of real-time MRI guidance for intra-articular injections of the temporomandibular joints resulting in an overall technical accuracy of 100%. We, therefore, wish to provide this necessary reference to the readers of Pediatric Radiology [3].

Dr. Parra and colleagues...
