Imaging of the wrist joint has been radically modified over the last decade, particularly since multidetector computed tomography (MDCT) arthrography and magnetic resonance (MR) arthrography have become widely available. These two modalities allow a confident assessment of ligament tears and potential diagnosis of associated abnormalities of cartilage, bone, and soft tissues. The interosseous scapholunate and lunotriquetral ligaments and the triangular fibrocartilage complex (TFCC) are the most important structures to consider. Precise analysis of their different lesions, including recognition of degenerative tears, is essential for guiding the treatment. After a brief overview of the different injuries of interosseous ligaments and cartilage, this article thoroughly exposes the technical aspects of wrist MDCT arthrography and MR arthrography, reviews their results, and discusses their performances in light of recent literature. Finally, we propose an imaging strategy to decide between MDCT arthrography and MR arthrography depending on the clinical query. Other imaging modalities are not forgotten in this strategy. The evaluation of ligamentous and TFCC pathology must always begin with conventional radiographs. Cineradiography, ultrasound, and standard MRI are also useful in selected cases.

Computed tomography (CT) is a common modality employed for musculoskeletal imaging. Conventional CT techniques are useful for the assessment of trauma in detection, characterization and surgical planning of complex fractures. CT arthrography can depict internal derangement lesions and impact medical decision making of orthopedic providers.

Osteoarthritis (OA) is a prevalent disease and the leading cause of pain, disability, and quality of life deterioration. Our study sought to evaluate the image quality and dose of cone-beam computed tomography arthrography (CBCT-A) and compare them to digital radiography (DR) for OA diagnoses. Overall, 32 cases of CBCT-A and DR with OA met the inclusion criteria and were prospectively analyzed.

Article Synopsis
- The study aimed to evaluate and compare the effectiveness of computed tomographic arthrography (CTA) and 3-Tesla magnetic resonance imaging (MRI) in identifying artificial cartilage lesions in equine knee joints.
- A total of 79 cartilage defects were created in horse cadavers, and both imaging methods were analyzed for their sensitivity and specificity by a radiologist unaware of the lesions.
- Results indicated that while MRI had a slightly higher sensitivity (66% vs. 53%), CTA demonstrated significantly better specificity (66% vs. 52%), suggesting that CTA might be a more accurate choice for diagnosing normal cartilage, particularly in a clinical environment where it is more accessible.
Influence of joint volume on range of motion after arthroscopic rotator cuff repair.

Article Synopsis
- Capsular contracture can lead to postoperative stiffness in shoulders after arthroscopic rotator cuff repair (ARCR), making it important to measure joint volume as it may affect recovery.
- The study reviewed 83 patients who had ARCR, using computed tomography arthrography (CTA) to quantify joint volume and evaluate shoulder range of motion (ROM) six months after surgery.
- Results showed moderate correlations between total joint volume and specific shoulder motions, indicating that larger joint volumes could be linked to better postoperative shoulder mobility.

Modern cone-beam CT systems are capable of ultra-high-resolution 3D imaging in addition to conventional radiography and fluoroscopy. The combination of various imaging functions in a multi-use setup is particularly appealing for musculoskeletal interventions, such as CBCT arthrography (CBCTA). With this study, we aimed to investigate the feasibility of CBCTA of the wrist in a "one-stop-shop" approach with a gantry-free twin robotic scanner that does not require repositioning of subjects.
