“…While the concentration injected is lower than in systemic studies with 30-40 mg I/mL preferred by some investigators [87,89,91], others use 100-150 mg I/mL successfully [81,88]. To prolong agent retention, the use of dimers or epinephrine is described [92,93], but is unnecessary if the scan is performed promptly following injection (B. Nelson; unpublished observations 2016). Without maximal distention, gravity dependence influenced by the horse's recumbency may cause some articular structures to not be in contact with the ICM [89].…”

The use of contrast media in computed tomography (CT) and magnetic resonance imaging (MRI) is increasing in horses. These contrast-enhanced imaging techniques provide improved tissue delineation and evaluation, thereby expanding diagnostic capabilities. While generally considered safe, not all contrast media exhibit the same safety profiles. The safety of contrast media use and descriptions of adverse events occurring in horses are sparsely reported. This review summarises the reported evidence of contrast media use and adverse events that occur in horses, with added contribution from other veterinary species and studies in man for comparison. This comprehensive data set empowers equine clinicians to develop use and monitoring strategies when working with contrast media. Finally, it summarises the current state-of-the-art and highlights the potential applications of contrast-enhanced CT and MRI for assessment of diseased or injured equine tissues, as well as (patho)physiological processes.

“…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.

“…Computed tomographic arthrography (CTA) has also been considered as a method to visualize canine shoulder soft tissue structures and thus for the diagnosis of shoulder joint injuries. 7,[12][13][14][15][16][17][18] However, one recent study indicated that CTA alone was of limited diagnostic value to assess the medial glenohumeral ligament (sensitivity and specificity of 13% and 1%, respectively) and the subscapularis tendon. 19 Arthroscopy is currently the gold standard technique to assess medial shoulder joint instability in dogs, as it provides direct information on the intra-articular structures, especially the medial glenohumeral ligament.…”

Medial glenohumeral ligament injury is commonly reported during medial shoulder joint instability in dogs. Arthroscopy is considered the gold standard procedure, but it is invasive and requires distension of the joint. Ultrasonographic examination of the medial glenohumeral ligament has been studied as a possible, less invasive alternative to arthroscopy however it has not been considered a useful method of assessment due to the interference of the probe with the pectoral muscles. The aims of this prospective analytical randomized pilot study were to develop a standardized ultrasound protocol for visualizing the canine medial glenohumeral ligament and to compare goniometry and ultrasound findings in cadaver dogs with versus without transection of the medial glenohumeral ligament. Nine adult Beagle cadavers (18 shoulders) were used. The first six shoulders were used in a preliminary study to describe an ultrasound technique to identify the medial glenohumeral ligament. Arthroscopy was performed on the remaining 12 shoulders, with six randomly selected medial glenohumeral ligaments from these shoulders, transected during the procedure. Ultrasound examination was performed after each arthroscopic procedure by an ultrasonographer blinded to the patient group. Four medial glenohumeral ligaments (67%) were correctly identified during the preliminary study. Ultrasonographic examination failed to diagnose the transection of all six medial glenohumeral ligaments in the second part of the study. No difference was observed in the ligament thickness between the dogs with and without a transected medial glenohumeral ligament. Dogs with a transected medial glenohumeral ligament had a wider articular space compared to dogs without a transected ligament (P < 0.001), and an articular space wider than 8.2 mm was discriminatory of a transected medial glenohumeral ligament in all the shoulders. In conclusion, the medial glenohumeral ligament could be identified with a medial ultrasonographic approach of the shoulder and a wider articular space can be a sign of a medial shoulder joint instability. Further studies are needed to confirm these preliminary findings in living dogs, with and without shoulder instability.
