“…Furthermore, the presence of contrast medium intensified the contrast‐to‐noise ratio, offering a better visualization for some extra‐articular structures such as the tendon of the musculus flexor carpi ulnaris. These findings are in agreement with previous reports that described the benefits of MRA in the visualization of intra‐articular structures, such as the cruciate ligaments of the stifle joint and the biceps tendon of the shoulder joint in dogs . These findings are in contrast to literature in human medicine, in which CTA is considered as accurate or even more accurate than conventional 3 Tesla MRI for detecting tears of the intrinsic ligaments, such as the scapholunate and lunotriquetral ligaments .…”

Objective To compare the quality of visualization of canine carpal ligaments by using computed tomography (CT), MRI, CT arthrography (CTA), and magnetic resonance arthrography (MRA). Study design Prospective descriptive study. Study population Cadavers from dogs weighing more than 20 kg. Methods A 16‐slice CT scanner and a 3 Tesla MRI were used for the investigation. A dilute contrast medium was injected into the middle carpal and radiocarpal joints under fluoroscopic control, and CTA and MRA images were acquired. To evaluate the difference between imaging modalities, 3 observers graded carpal ligaments of clinical interest using a scale from 0 to 4 for their quality of visualization. Data were analyzed by using a random‐effect ordinal logistic regression with Bonferroni adjustment. The interobserver agreement was calculated by using the weighted Cohen's κ. Results Normal carpal joints (n = 9) were investigated. Magnetic resonance arthrography improved visualization of the majority of carpal ligaments compared with MRI (P < .05) and offered the best visualization overall. Magnetic resonance imaging and MRA offered better visualization compared with both CT and CTA (P < .05). There was no difference between CT and CTA. Interobserver agreement was discrete (0.2 < κ ≤ 0.4) for all observers. Conclusion Arthrography improved the capabilities of MRI but not of CT for visualization of the canine carpal ligaments. Magnetic resonance arthrography was particularly useful for evaluation of the stabilizers of the antebrachiocarpal joint. Clinical significance 3 Tesla MRA and MRI allow excellent visualization of the ligamentous morphology and may be helpful in the diagnostic process of carpal sprains in dogs.

“…Potential risks of positive contrast arthrography include the introduction of infection, synovial irritation, hemorrhage, postprocedural pain, contrast extravasation, and systemic reactions. According to published data these complications are considered rare . Iohexol, used in this study, is a nonionic, low osmolar monomeric agent, which causes minimal synovial inflammation .…”

“…Positive contrast arthrography of the canine shoulder has been reported to aid in the diagnosis of osteochondrosis disorder, bicipital tenosynovitis, aseptic arthritis, osteochondromatosis, rupture of the biceps brachii tendon sheath, and neoplasia . Computed tomography and computed tomography arthrography have been demonstrated in canine cadavers to describe, in detail, the intraarticular structures of the normal canine shoulder . To the authors’ knowledge, an extensive comparison of CT and computed tomography arthrography of the canine shoulder in clinical cases has not yet been reported.…”

The aim of this retrospective, methods comparison study was to assess the diagnostic utility of computed tomographic arthrography in the assessment of various intraarticular shoulder pathologies in dogs in comparison with survey computed tomography (CT), using arthroscopic examination as the reference standard. Computed tomography, computed tomographic arthrography, and arthroscopic findings of 46 scapulohumeral joints of dogs with forelimb lameness were reviewed retrospectively. Predefined sites were assessed for the presence or absence of disease. If a lesion was present, a prespecified pathology was designated. Computed tomographic arthrography was found to be a safe technique which provided a superior diagnostic efficacy relative to survey CT for the assessment of the biceps tendon and biceps tendon sheath (sensitivity 71%, specificity 75%, positive likelihood ratio 2.9, negative likelihood ratio 0.38) and humeral head cartilage (sensitivity 65%, specificity 97%, positive likelihood ratio 19, negative likelihood ratio 0.37). Computed tomography and computed tomographic arthrography provided additional diagnostic information to arthroscopy in regard to osteophytosis, subchondral defects, and joint mice. Computed tomographic arthrography alone was of limited diagnostic value for assessment of the medial and lateral glenohumeral ligaments (sensitivity 13% and 0%, specificity 1% and 78%, positive likelihood ratios unmeasurable and 0, negative likelihood ratios 0.88 and 1.29, respectively) and the subscapularis tendon (sensitivity 14%, specificity 98%, positive likelihood ratio 5.7, negative likelihood ratio 0.88). Computed tomographic arthrography is therefore a useful adjunct to survey CT and arthroscopic evaluation of the canine shoulder joint, however, is not a replacement for these techniques.

“…9 Thus, arthroscopy, magnetic resonance imaging, magnetic resonance arthrography and computed tomographic arthrography are often required to see shoulder soft tissue structures and diagnose shoulder injuries, but these are less commonly available and are more expensive diagnostic tools. 8,[10][11][12][13][14][15][16] The objective of our study was to describe a new technique for stress radiography allowing an accurate diagnosis of medial glenohumeral ligament rupture and medial shoulder instability. Moreover, our purpose was to investigate the repeatability (intra-observer agreement) and reproducibility (inter-observer agreement) of this new radiographic technique.…”

Objectives This study aimed to describe a stress radiography to detect medial glenohumeral ligament rupture and to investigate the repeatability and reproducibility of this test. Materials and Methods Six adult Beagle cadavers were used. Both shoulders of each dog were randomly assigned into two groups: a normal shoulder group (NS group) and an affected shoulder group (AS group) where the medial glenohumeral ligament was arthroscopically transected. Goniometry, image analysis and radiography (normal and stress views) were performed before and after arthroscopic procedures. An abduction angle was determined for each stress view and an evaluation of the repeatability and the reproducibility was performed. Results Abduction angles were significantly larger in the AS group as measured by goniometer (p < 0.001), image analysis (p < 0.001) and radiographic stress view (p < 0.001) than in the NS group. The abduction angle difference varied from 12° to 29.3° (median difference of 19.4°) between NS and AS groups. There were good intra-observer and very good inter-observer agreements. A very good (r = 0.74; r = 0.72, respectively) significant (p < 0.001) positive correlation between goniometric and radiographic techniques and between image analysis and radiographic techniques was observed. Clinical Significance Shoulder abduction angles measured with a stress radiograph-specific view provide objective data that may contribute to diagnosis of medial shoulder instability in dogs.
