Summary
High-resolution multidetector computed tomography (MDCT) arthrography is effective for diagnosing shoulder joint derangements. This technique aids in visualizing rotator cuff, labrum, and cartilage issues, even with metal implants.
Area of Science:
- Radiology
- Orthopedics
- Medical Imaging
Background:
- Internal derangement of the glenohumeral joint requires accurate diagnostic methods.
- Multidetector computed tomography (MDCT) arthrography offers high-resolution imaging capabilities.
Purpose of the Study:
- To review the indications for MDCT arthrography of the shoulder.
- To highlight MDCT acquisition techniques and important imaging features.
- To review normal and abnormal MDCT arthrography findings of the glenohumeral joint.
Main Methods:
- Utilizing high-resolution multidetector computed tomography (MDCT) arthrography.
- Employing isotropic data sets and advanced postprocessing for interactive 3D analysis.
- Techniques to reduce artifacts associated with metal implants.
Main Results:
- MDCT arthrography effectively diagnoses internal derangements of the shoulder.
- Abnormalities of the rotator cuff, glenoid labrum, and articular cartilage are visualized.
- 3D analysis reduces artifacts, improving imaging in patients with metal implants.
Conclusions:
- MDCT arthrography is a valuable tool for evaluating shoulder internal derangements.
- The technique provides detailed assessment of key glenohumeral joint structures.
- It offers improved diagnostic accuracy, particularly in complex cases involving implants.
