Background:
the protocol for mobilization of the fetlock region prior to acquiring a contrast tenogram radiograph is not clearly defined.
Objective:
to determine if walking exercise improves identification of DFTS pathology on contrast tenography.
Methods:
Prospective cohort study. Nineteen horses that underwent contrast tenography and subsequent surgical tenoscopy were included. A tenogram protocol was developed to enable comparison of diagnostic accuracy after increasing mobilization of the affected limb post-injection. Following contrast injection three tenogram radiographs were taken, (1) immediately post-injection, (2) after manual fetlock flexion, (3) after walking. Tenoscopic findings were compared with radiological diagnosis.
Results:
The detection rate for both MF and DDFT tears improved with increasing limb mobilization (static
Conclusions:
Walking exercise prior to contrast tenogram acquisition improves diagnostic accuracy for detecting MF and DDFT tears. Walking exercise should be undertaken as standard for contrast tenograms for accurate diagnosis.

Description of the Procedures
Computed Tomography (CT) scan:
Computed Tomography (CT) scans use X-ray technology to generate detailed images of bones, organs, and tissues. During the scan, the patient lies on a moving table...

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
