“…Among them the following may be mentioned: dorsal recumbency with extended (Baird et al 1999, Martig et al 2006 or flexed hindlimbs (Bottcher et al 2010, Tremolada et al 2014, lateral recumbency with various flexion angles of the stifle (Barrett et al 2009, Podadera et al 2014, or even in sternal recumbency (Harper et al 2011). Pujol et al (2011 reported that lateral recumbency with the stifle flexed at 145 o changed the tension of the cranial cruciate ligament and improved its visibility.…”

“…One of the difficulties encountered in imaging is the thickness of the stifle articular cartilage, which is between 0.6-1.3 mm (Pujol et al 2011). Cross-section images obtained by magnetic resonance imaging is an excellent tool to recognize early osteophytes (Carrig 1997, D'Anjou et al 2008.…”

“…However, during the anatomic study of the meniscus in the low magnetic field heterogeneous signal increase in the center was observed. The authors supposed that it was due to the gradient echo sequence used and its hyperintense effect (Martig et al 2006, Blond et al 2008, Pujol et al 2011. Similarly, in a high-field study Barrett et al (2009) defined as an entire meniscus with intrameniscal increased signal intensity that did not reach meniscal margins.…”

“…MRI has become the preferred noninvasive imaging modality for the evaluation of normal stifle joints. It is also a particularly useful diagnostic tool for stifle injuries and secondary changes (Widmer et al 1991, Conaghan et al 2006, D'Anjou et al 2008, Pujol et al 2011, Tremolada et al 2014) Among these changes, lesions of cruciate ligaments, menisci, synovitis, cartilage lesions, osteoarthritis and neoplastic tumors stand out.…”

The most common cause of hindlimb lameness in dogs is cranial cruciate ligament rupture. In 48-77.3% of the population this trauma leads to secondary damage of the meniscus. Depending on the magnetic strength of the used device, different diagnostic accuracy can be achieved. The examination sensitivity of magnetic resonance imaging is affected by many factors which are independent of diagnostic strength, such as correct positioning of the patient, size of the stifle joint examined, or selection of the right protocol of sequences. Sensitivity of meniscus damage detection was 100% and 90%, respectively, in high-and low-field magnetic resonance. The best results were reported during examination of the stifle in dogs above 10 kg b.w. at a flexion angle of 145 o , and in sagittal and dorsal planes. Regardless of the magnetic strength applied, imaging of the whole cranial cruciate ligament is difficult. Moreover, MRI allows the detection of the first signs of osteoarthritis, which were observed 4 and 6 weeks after rupture of the cranial cruciate ligament using high and low-field MRI. This also applies to lesions in the subchondral bone or a bone marrow which occurred in association with insufficiency of the stifle joint, and were mainly localized in the epiphysis of the femur and tibia. The present article provides a comparison of different examination protocols and images of damaged stifle structures, such as menisci, ligaments and bones of the stifle joint visualized with low-field and high-field magnetic resonance. Magnetic resonance arthrography is also discussed.
