Sonographic features of canine shoulder osteochondrosis (OCD)
I have blogged about this before:
However, at that stage I hadn’t found this:
Vet Radiol Ultrasound. 2015 Jan-Feb;56(1):3-11. doi: 10.1111/vru.12179. Epub 2014 May 21.
Diagnostic sensitivity of radiography, ultrasonography, and magnetic resonance imaging for detecting shoulder osteochondrosis/osteochondritis dissecans in dogs.
Wall CR1, Cook CR, Cook JL.
Which, happily, demonstrated that ultrasonography was broadly comparable to radiography in the detection of shoulder OCD lesions.
‘Diagnostic sensitivity, specificity, and accuracy (correct classification rate) values for detecting presence or absence of shoulder osteochondrosis/osteochondritis dissecans were as follows: radiography (88.5%, 90%, 88.9%), ultrasonography (92%, 60%, 82.6%), and MRI (96%, 88.9%, 94.4%)‘
Sonography is obviously highly dependent on machine/probe specifications and technique. In an exciting development, we are proud to include the amazing images of Bob Hylands from Ontario acquired using a Logiq S8 linear matrix probe: they are the best I’ve seen.
This is one of mine (Logiq R7 linear probe):
This is the appearance of that OCD lesion at arthroscopy.
