    Abstract This article provides a review of magnetic resonance neurography (MRN) and how to get started. It explains step by step how to establish MRN at an institution: how to set up MRN protocols, how to train technicians, what a report needs to contain, and how relevant findings should be communicated to the referring physician. Advanced imaging techniques such as diffusion tensor imaging are only briefly discussed at the end of the article because most of those techniques are difficult for beginners and are still not considered standard in the clinical routine.

    Abstract Application of paraclinical methods for investigating the temporomandibular joint (TMJ) has been a subject of constant controversy due to the absence of universally-accepted criteria and lack of consensus regarding their usage. Compared with medical imaging, which provides a structural analysis of the TMJ, axiography involves the functional recording of condylar movements. The aim of the present study was to explore the diagnostic value of computerized axiography for TMJ disc displacements using MRI as the reference standard. The present study included 33 (66 TMJs) patients clinically diagnosed with TMJ disc displacements. On the same day, all patients underwent clinical examination and computerized axiography measurements using Cadiax Compact

    Abstract Unlabelled: Magnetic resonance imaging (MRI) is the most accurate imaging technique in the diagnosis of meniscal lesions and represents a standard tool in knee evaluation. MRI plays a critical role in influencing the treatment decision and enables information that would obviate unnecessary surgery including diagnostic arthroscopy. An accurate interpretation of the knee depends on several factors, starting with technical aspects including radiofrequency coils, imaging protocol and magnetic field strength. The use of dedicated high-resolution orthopaedic coils with a different number of integrated elements is mandatory in order to ensure high homogeneity of the signal and high-resolution images. The clinical imaging protocol of the knee includes different MRI sequences with high-spatial resolution in all orientations: sagittal, coronal, and axial. Usually, the slice thickness is 3 mm or less, even with standard two-dimensional fast spin echo sequences. A common potential reason for pitfalls and errors of interpretation is the unawareness of the normal tibial attachments and capsular attachment of the menisci. Complete description of meniscal tears implies that the radiologist should be aware of the patterns and the complex classification of the lesions.
    Teaching points: • Technical factors may influence MRI interpretation. • Unawareness of the normal meniscal anatomy may lead to errors of interpretation. • Description of meniscal tears implies the knowledge of meniscal tear classification.

    Abstract Aim: The aim of this study was to evaluate if the increased temporomandibular joint (TMJ) capsular thickness, measured by ultrasound (US), is associated with the presence of effusion, diagnosed using MRI imaging. Materials and Methods: 102 patients with signs and symptoms of temporomandibular disorders were included in the study. Each patient underwent US and MRI examinations, 1 to 5 days following clinical examination. The US was performed with an 8−40 MHz linear transducer operating at 20 MHz. The MRI was performed using a 1.5 T MRI device. The ROC curve was analyzed to identify the optimal cut-off value for capsular distention, which can be interpreted as an indirect sign of TMJ effusion. Results: The capsular width values were found to be between 0.7 and 3.6 mm. The best cut-off value was 2.05 mm with a sensitivity of 55.9% and a specificity of 94.7%. The next optimal cut-off value was 1.75 mm with a sensitivity of 67.6% and a specificity of 82.4%. The area under the ROC curve was 0.78 (95% CI 0.68, 0.87, p < 0.05). Conclusions: Ultrasound-measured capsular width can be interpreted as an indirect sign of TMJ effusion. The critical cut-off for capsular width was 2 mm.

    Abstract Purpose: The study aims to determine the diagnostic value of high-resolution ultrasonography (US) compared with magnetic resonance imaging (MRI) for the evaluation of temporomandibular disorders (TMD).
    Methods: Fifty consecutive patients (42 female and 8 male) with signs and symptoms of TMD according to the Research Diagnostic Criteria for TMD were enrolled in the study. Each patient underwent US (13 and 20 MHz) and MRI examination of both TMJs, 1-7 days following clinical examination. All MRI examinations were performed by another radiologist using an 1.5 T MRI device. Sensitivity (Se), specificity (Sp), positive and negative predictive values (PPV, NPV) and diagnostic accuracy were computed along with 95% confidence intervals.
    Results: For overall disc displacements, 13 MHz US showed a Se of 72.58%, Sp of 86.84%, PPV of 90%, NPV of 66% and diagnostic accuracy of 78%, while 20 MHz US showed a Se of 75.81%, Sp of 86.84%, PPV of 90.38%, NPV of 68.75% and a diagnostic accuracy of 80%. For degenerative changes, 13 MHz US revealed a Se of 58.33%, Sp of 92.11%, PPV of 70%, NPV of 87.5% and a diagnostic accuracy of 84%, whereas 20 MHz US indicated the same Se of 58.33%, Sp of 93.42%, PPV of 73.68%, NPV of 87.65% and a diagnostic accuracy of 85%. The Cohen's Kappa coefficient for the intra- and inter-observer agreement was 0.822 and 0.836 for disc displacement, respectively 0.813 and 0.788 for degenerative disorders (p < 0.001).
    Conclusions: High-resolution US could be a useful imaging technique in diagnosing TMJ disc displacements.

    Abstract Background: The article presents a rare case of acute malocclusion produced by a unilateral partial tear of the lateral pterygoid muscle and an up-to-date literature review of the pathology.
    Clinical presentation: A 37-year-old female was examined; her chief complaints were pain on the right side of the temporomandibular joint (TMJ) area and mastication impairment associated with major occlusal modifications and anterior open bite. After magnetic resonance imaging (MRI) and cone beam computed tomography (CBCT) of the TMJ and subsequent MRI for soft tissue, the final diagnosis was a partial right lateral pterygoid muscle tear.
    Conclusion: The case shows the value of combined imaging in temporomandibular disorders (TMD) and the importance of soft tissue evaluation in addition to articular examination, as the primary pathology might lie outside the joint. The authors' review of the current literature did not hitherto reveal a similar case.

    Abstract This book is divided into chapters that cover MRI of all structures of the knee joint in the order that is usually used in practice - cruciate ligaments, collateral ligaments, menisci, cartilage, subchondral bone, patella, synovia, muscles and tendons, arteries, veins and bones. With the aid of numerous images, each chapter provides comprehensive descriptions of the anatomy, the normal MR appearance, pathological MR findings, and postoperative MRI appearance. A text box at the end of each chapter clearly describes how the MRI report should be compiled and identifies what should be included when reporting on specific lesions. The book will be an ideal guide for radiologists and will also be relevant for orthopaedic surgeons, rheumatologists, and physiotherapists
