Abstract

Computed tomography (CT) and magnetic resonance (MR) image features of the temporomandibular joint (TMJ) and associated structures in two mature dromedary camels were obtained with a third-generation equipment CT and a superconducting magnet RM at 1.5 Tesla. Images were acquired in sagittal and transverse planes. Medical imaging processing with imaging software was applied to obtain postprocessing CT and MR images. Relevant anatomic structures were identified and labelled. The resulting images provided excellent anatomic detail of the TMJ and associated structures. Annotated CT and MR images from this study are intended as an anatomical reference useful in the interpretation for clinical CT and MR imaging studies of the TMJ of the dromedary camels.

Partial Text

The temporomandibular joint (TMJ) is a synovial condylar joint between the base of the zygomatic process of the temporal bone and the condylar process of the mandible; its main articular components are the synovial pouches, articular disc, caudal and lateral ligaments, and joint capsule [1].

In this study, anatomical structures of the TMJ of the mature camel were identified and labelled in five figures (Figures 1, 2, 3, 4, and 5).

To the authors’ knowledge, there are no detailed published studies of the TMJ of the dromedary camel using CT and MRI, which turns out to be essential for morphologic, physiologic, and clinical studies involving bones and soft tissues located in this joint.

Our study contribute to a better anatomical knowledge of the TMJ of the dromedary camel by means of CT and MRI and is a useful initial reference for clinical studies. CT is an excellent method for the detailed assessment of the bony structures. MRI is a valid imaging modality for the evaluation of the soft tissues. The FSE T1-weighted sequence should be the baseline to identify the anatomy, and FSE T2-weighted sequence will better enhance the study of the articular surfaces and articular disc. The after processing of CT and MR images allowed us to appreciate different bone structures and soft tissues of the TMJ, assisting in the interpretation of the images.
