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.
