Abstract

The computed tomography (CT) scan is currently the gold standard in the imaging of orbital fractures. The weak points of this imaging modality, however, include restricted soft tissue depiction as well as the radiation. Both attributes are of particular importance in children because of the high rate of trapdoor fractures and the radiation to the lens. Although magnetic resonance imaging (MRI) is not associated with these drawbacks, it has not been established in the primary diagnosis of pediatric orbital fractures. The aim of our study was to establish the use of MRI with a special orbital coil for the primary diagnosis of pediatric orbital trauma. In our retrospective study, 14 pediatric patients presented to our department with a blunt orbital trauma from 2003 to 2007. Twelve of 14 patients with orbital floor fractures required surgical reconstruction. Until 2004, imaging was carried out by plain x-rays and CT scan for a decision regarding the necessity of surgery. Since introducing the MRI microscopy orbital coil in 2004, CT scans have been replaced by MRI for the primary fracture diagnosis in 8 pediatric cases. Kappa statistics have been applied to assess inter- and intraobserver reliability for CT scans and MRI. This stud...Continue Reading

Cajal Bodies & Gems

Cajal bodies or coiled bodies are dense foci of coilin protein. Gemini of Cajal bodies, or gems, are microscopically similar to Cajal bodies. It is believed that Cajal bodies play important roles in RNA processing while gems assist the Cajal bodies. Find the latest research on Cajal bodies and gems here.
