Comparison of the accuracy of radiography and ultrasonography for detection of articular lesions in horses.

The research article investigates the accuracy of two methods: ultrasonography and radiography for detecting articular lesions in horses. The authors concluded that ultrasonography examination was more accurate than radiography.

Methods

• The study was a cross-sectional study involving 137 horses with articular lesions.
• Both radiographic and ultrasonographic examinations of the affected joint(s) in the horses were carried out before any diagnostic or therapeutic arthroscopic surgery.
• The findings from these examinations were then recorded and compared with the lesions identified during arthroscopy.

Results

• A total of 432 lesions in 254 joints were identified by arthroscopy.
• The overall accuracy was higher for ultrasonography (82.9%) compared to radiography (62.2%).
• In terms of sensitivity, ultrasonography also outperformed radiography with values of 91.4% and 66.7% respectively.
• There was no significant statistical difference in specificity between the two methods.
• The research also evaluated the negative predictive value, which was higher for ultrasonography (31.5%) in comparison to radiography (13.2%).
• Both ultrasonography and radiography demonstrated equal accuracy for detecting lesions in left versus right joints, aligning with the overall results.

Conclusions

• The authors concluded that ultrasonographic evaluation of articular lesions is more accurate than radiographic evaluation.
• This means the use of ultrasonography might be more effective than radiography in a clinical setting for accurate detection of articular lesions in horses. This could lead to better diagnosis and treatment.
