Figure 2From: Diagnostic accuracy of a short-duration 3 Tesla magnetic resonance protocol for diagnosing stifle joint lesions in dogs with non-traumatic cranial cruciate ligament ruptureExamples of PDW images (dorsal plane) illustrating the osteoarthritis scoring system. The images belong to patients correctly graded according to the scoring system described in Table 2. a (Score 0): Osteophytes absent. b (Score 1): Osteophytes present on the patella (not shown) and proximal aspect of the femoral trochlear groove (arrow). c (Score 2): Osteophytes present on the patella (white arrow), femoral trochlear groove (yellow arrow), medial and lateral femoral condyles (orange arrows) and tibial plateau (green arrow). d (Score 3): Severe osteophytes on the patella (not shown), femoral trochlear groove (yellow arrow), medial and lateral femoral condyles (orange arrows) and tibial plateau (green arrow).Back to article page
