Diagnostic performance of CT-arthrography and 1.5T MR-arthrography for the assessment of glenohumeral joint cartilage: a comparative study with arthroscopic correlation

Abstract

• CTA has moderate diagnostic performance for detecting glenohumeral cartilage substance loss. • MRA has moderate diagnostic performance for detecting glenohumeral cartilage substance loss. • CTA is more accurate than MRA for detecting cartilage substance loss.

Reliable semiquantitative whole‐joint MRI score for the shoulder joint: The shoulder osteoarthritis severity (SOAS) score

“…Due to the thin cartilage layer, assessment of cartilage defects at the shoulder is more challenging than at the knee joint. While previous studies reported a good reliability of 0.83–0.87 with respect to detection of cartilage defects on shoulder MR arthrographies, in the current study it was demonstrated that good to excellent reliability of cartilage lesion scoring is also possible on noncontrast MRI. This good‐to‐excellent reliability may be due to improved MR techniques, signal‐to‐noise ratio, and image resolution.…”

“…For other joints, such as the knee and hip joint, several whole‐joint MRI‐based scoring systems have been published . But for the shoulder joint, available scores only consider selected individual joint structures, such as the rotator cuff or cartilage lesions …”

New approach for predictive measurement of knee cartilage defects with three-dimensional printing based on CT-arthrography: A feasibility study

“…Previous studies already showed that CTA compared to MRI is a valuable method for depiction of cartilage lesions of the knee with high sensitivity and specificity. 16,28 Using a section thickness of 0.7 mm and contrast agent a realistic and accurate assessment of the cartilage and defect zone was possible. As the results show, CTA could enable a more accurate depiction and measurement of defect-size.…”

“…[16][17][18] It benefits from the intra-articular injection of contrast fluid, and CTA has the advantage of a high spatial resolution as well as a high contrast between the hypodense cartilage and hyperdense surrounding bone and contrast fluid.…”

“…16 With the rapidly advancing technique of three-dimensional printing (3D printing) a new technology is about to revolutionize medicine. 3D printing is a methodology using 3D CAD (computeraided design) datasets for producing 3D physical model.…”
