To compare the accuracy of ultrasonographic and radiographic examination for evaluation of articular lesions in horses.
Cross-sectional study.
Horses (n = 137) with articular lesions.
Radiographic and ultrasonographic examinations of the affected joint(s) were performed before diagnostic or therapeutic arthroscopic surgery. Findings were recorded and compared to lesions identified during arthroscopy.
In 254 joints, 432 lesions were identified by arthroscopy. The overall accuracy was 82.9% for ultrasonography and 62.2% for radiography (P < .0001) with a sensitivity of 91.4% for ultrasonography and 66.7% for radiography (P < .0001). The difference in specificity was not statistically significant (P = .2628). The negative predictive value for ultrasonography was 31.5% and 13.2% for radiography (P = .0022), the difference for the positive predictive value was not statistically significant (P = .3898). The accuracy for ultrasonography and radiography for left versus right joints was equal and corresponded with the overall results.
Ultrasonographic evaluation of articular lesions was more accurate than radiographic evaluation.
比较超声检查和放射检查在评估马关节病变方面的准确性。
横断面研究。
患有关节病变的马（n = 137）。
在诊断性或治疗性关节镜手术前，对患关节进行放射检查和超声检查。记录检查结果，并与关节镜检查中发现的病变进行比较。
在254个关节中，关节镜检查发现432处病变。超声检查的总体准确率为82.9%，放射检查为62.2%（P <.0001），超声检查的敏感性为91.4%，放射检查为66.7%（P <.0001）。特异性差异无统计学意义（P =.2628）。超声检查的阴性预测值为31.5%，放射检查为13.2%（P =.0022），阳性预测值差异无统计学意义（P =.3898）。超声检查和放射检查对左、右关节的准确性相同，与总体结果一致。
关节病变的超声评估比放射评估更准确。
