AI Article Synopsis
- The study aimed to evaluate how adding epinephrine to computed tomographic arthrography (CTA) affects image clarity of specific structures in the canine shoulder, including ligaments, the biceps tendon, and cartilage.
- Eight normal dogs underwent scans with two different contrast agents: Iohexol alone for one shoulder and a combination of Iohexol plus epinephrine for the other.
- Results showed that the mixture of epinephrine and Iohexol significantly improved image sharpness for certain shoulder structures, particularly in later scans, without hindering recovery after the procedure.
Article Abstract
The aim of this study was to investigate the effect of epinephrine-enhanced computed tomographic arthrography (CTA) on the image sharpness of the lateral and medial glenohumeral ligaments (LGHL and MGHL, respectively), biceps tendon (BT) and joint cartilage (JC) in the canine shoulder. The shoulders of eight normal dogs were examined using a 4-slice helical CT scanner. The right shoulders were injected with Iohexol and the left shoulders with a mixture of Iohexol and epinephrine. CTA images were obtained after 1, 3, 5, 9, 13, 20 and 30 min and the image sharpness of the intra-articular structures in both shoulders was graded for visibility. The attenuation values were measured to examine the persistence of contrast appearance. Admixture of epinephrine and Iohexol significantly improved the image sharpness of the LGHL and the BT, especially on delayed CTA images. The use of epinephrine did not negatively affect post-CTA recovery.
