The article discusses the possibilities and search for the optimal concept of diagnosis of hand osteoarthritis (OA). The data of numerous studies with focus on the comparison of sensitivity and specificity of the main techniques in this type of pathology – standard radiography and magnetic resonance imaging (MRI) are presented. Determination of the earliest symptoms of OA allows to predict the development of the disease and begin its therapy. The joint space narrowing due to the loss of articular cartilage is the earliest radiological symptom of OA, which is observed in the advanced stage of the disease. MRI, unlike radiography, makes it possible to visualize the articular cartilage, fluid in the joint cavity, bone marrow edema and soft tissues, but it is more expensive and time-consuming method. At present the main difficulty lies in the absence of a standardized system for assessing the MRI hand OA manifestations, as well as insufficient number of investigations in this area.

Application Fields

Magnetic resonance imaging (MRI) is currently one of the essential imaging methods in medicine. Since it is a noninvasive method that does not use ionizing radiation, its applications are getting more and more attention in the dentistry field. MRI is specifically used for the evaluation of soft tissues. Temporomandibular disorders, paranasal sinuses, determination of lesion contents and endodontics are just some of the application subjects. The aim of this review is to inform dentists and oral surgeons about the application fields of MRI.

AbstractDue to their important phylogenetic position among extant vertebrates, sharks are an invaluable group in evolutionary developmental biology studies. A thorough understanding of shark anatomy is essential to facilitate these studies and documentation of this iconic taxon. With the increasing availability of cross-sectional imaging techniques, the complicated anatomy of both cartilaginous and soft tissues can be analyzed non-invasively, quickly, and accurately. The aim of this study is to provide a detailed anatomical description of the normal banded houndshark (Triakis scyllium) using computed tomography (CT) and magnetic resonance imaging (MRI) along with cryosection images. Three banded houndsharks were scanned using a 64-detector row spiral CT scanner and a 3 T MRI scanner. All images were digitally stored and assessed using open-source Digital Imaging and Communications in Medicine viewer software in the transverse, sagittal, and dorsal dimensions. The banded houndshark cadavers were then cryosectioned at approximately 1-cm intervals. Corresponding transverse cryosection images were chosen to identify the best anatomical correlations for transverse CT and MRI images. The resulting images provided excellent detail of the major anatomical structures of the banded houndshark. The illustrations in the present study could be considered as a useful reference for interpretation of normal and pathological imaging studies of sharks.

Magnetic resonance imaging (MRI), a useful technique of studying soft tissues of the body, can be very effective in assessing the integrity of tendons. Usually a patient with a complete tear of the posterior tibial tendon has characteristic physical findings. In the patient presented, MRI demonstrated a complete disruption of the posterior tibial tendon, despite the absence of the commonly associated clinical findings. In view of the difficulties encountered with attempted tenography of the completely torn posterior tibial tendon, MRI provides a sensitive alternative diagnostic technique.
