To assess the effectiveness of two enhancement filters for magnetic resonance images of temporomandibular joint (TMJ) in patients with juvenile idiopathic arthritis (JIA).
Magnetic resonance image (MRI) of 44 patients with JIA (15 males and 29 females) was analysed using OnDemand 3D software. Two experienced evaluators who were previously calibrated and blinded to the images assessed them subjectively regarding the use of Sharpen 1 and Sharpen 2 filters. The quality of the images after using the two different enhancement filters was compared to each other as well as to images without filter.
There was no statistically significant difference between Sharpen 1 and Sharpen 2 filters. Both filters provided significantly better images compared to images without filter (P = 0.000), resulting in a greater constancy of images with excellent diagnostic conditions. As for the evaluation of the articular eminences, Sharpen 2 filter provided images with better sharpness, despite the lack of a statistically significant difference.
The use of enhancement filters in MRI of patients with JIA was shown to be a valuable means to improve the diagnostic quality. Both Sharpen 1 and Sharpen 2 filters significantly enhanced the visualisation of mandibular condyles and articular eminences, thus potentially facilitating the detection and follow-up of JIA-related changes in these structures.
评估两种增强滤波器对幼年特发性关节炎（JIA）患者颞下颌关节（TMJ）磁共振成像的效果。
使用OnDemand 3D软件分析44例JIA患者（15例男性和29例女性）的磁共振图像（MRI）。两名经验丰富且事先经过校准并对图像不知情的评估人员对使用锐化1和锐化2滤波器的图像进行主观评估。将使用两种不同增强滤波器后的图像质量相互比较，并与未使用滤波器的图像进行比较。
锐化1和锐化2滤波器之间无统计学显著差异。与未使用滤波器的图像相比，两种滤波器均能提供明显更好的图像（P = 0.000），从而使图像在极佳诊断条件下具有更高的稳定性。至于关节结节的评估，尽管差异无统计学意义，但锐化2滤波器提供的图像清晰度更高。
在JIA患者的MRI中使用增强滤波器被证明是提高诊断质量的一种有价值的方法。锐化1和锐化2滤波器均能显著增强下颌髁突和关节结节的可视化，从而可能有助于检测和随访这些结构中与JIA相关的变化。
