Abstract

Objectives: To assess the effectiveness of two enhancement filters for magnetic resonance images of temporomandibular joint (TMJ) in patients with juvenile idiopathic arthritis (JIA).

Material: 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.

Results: 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.

Conclusion: 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.

改善青少年特发性关节炎的TMJ MRI诊断：图像增强滤波器的比较评价。

目的：评价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。资料：采用OnDemand 3D®软件对44例JIA患者（男15例，女29例）的磁共振图像（MRI）进行分析。两名经验丰富的评估人员对图像进行了校准和盲视，主观地评估了锐化1和锐化2滤镜的使用。对比了两种不同增强滤波器后的图像质量以及未加滤波后的图像质量。结果：锐化1滤镜与锐化2滤镜的差异无统计学意义。两种过滤器提供的图像都比没有过滤器的图像好得多（P = 0.000），从而使图像具有更好的稳定性，具有良好的诊断条件。对于关节突出度的评价，锐化2滤镜提供了更好的图像清晰度，尽管没有统计学上的显著差异。结论：在JIA患者MRI中应用增强滤光片是提高诊断质量的一种有价值的手段。锐化1和锐化2滤光片都能显著增强下颌髁突和关节突的显像，从而潜在地促进这些结构中jia相关变化的检测和随访。

期刊介绍： As the official English-language journal of the Japanese Society for Oral and Maxillofacial Radiology and the Asian Academy of Oral and Maxillofacial Radiology, Oral Radiology is intended to be a forum for international collaboration in head and neck diagnostic imaging and all related fields. Oral Radiology features cutting-edge research papers, review articles, case reports, and technical notes from both the clinical and experimental fields. As membership in the Society is not a prerequisite, contributions are welcome from researchers and clinicians worldwide.
