The objective of this study was to compare articular cartilage thickness observed in the different 2D and 3D sequences to the cartilage thickness of the equine stifle in cadavers to determine the accuracy of each sequence. The study was conducted as a blinded laboratory study using seven equine stifle specimens. The 2D (T2W TSE) and 3D (3D VIEW T2W HR, T2 3D mFFE, T1W VISTA SPAIR, 3D PDW SPAIR) 3-tesla MRI sequences of each stifle were obtained.

Nevertheless, making a precise preoperative diagnosis is challenging. This study aimed to determine and compare the sensitivity and specificity of low-field MRI and MRI tenography (MRIt) to detect artificially created soft-tissue lesions in the DFTS.

- The study aimed to evaluate and compare the effectiveness of computed tomographic arthrography (CTA) and 3-Tesla magnetic resonance imaging (MRI) in identifying artificial cartilage lesions in equine knee joints.
- A total of 79 cartilage defects were created in horse cadavers, and both imaging methods were analyzed for their sensitivity and specificity by a radiologist unaware of the lesions.
- Results indicated that while MRI had a slightly higher sensitivity (66% vs. 53%), CTA demonstrated significantly better specificity (66% vs. 52%), suggesting that CTA might be a more accurate choice for diagnosing normal cartilage, particularly in a clinical environment where it is more accessible.
Humans interact constantly with surfaces and associated microbial communities in the environment. The factors shaping the composition of these communities are poorly understood: some proposed explanations emphasize the influence of local habitat conditions (niche-based explanations), while others point to geographic structure and the distance among sampled locations (dispersal-based explanations). However, the relative roles of these different drivers for microbial community assembly on human-associated surfaces are not clear.
