Image optimization on magnetic resonance imaging (MRI) of brain with orthodontic bracket


Aryadiva N Prayoga, A Gunawan Santoso, Sugiyanto

Use of modalities Magnetic resonance imaging (MRI) has a vital role in the diagnosis of pathology that requires a picture with good tissue contrast. Another thing in the MRI modality that continues to be developed is the ability to reduce artifacts on examination. Artifacts due to Magnetic Susceptibility can occur at any MRI examination with the use of metal implants on the anatomy examined, one of which is the MRI Brain examination with the Orthodontic Bracket. The purpose of this study was to analyze the effectiveness of sequences to reduce metal artifacts due to the installation of Orthodontic Bracket. The type of research is quantitative analytical research with a quasi-experimental research design. The research design used was a posttest design to determine the optimization of the application of the sequence of Slice Encoding Metal Artifact Correction (SEMAC) and View Angle Tilting (VAT) on MRI Brain with Orthodontic Bracket. The results showed that SEMAC sequences combined with T2 TSE were able to reduce metal artifacts well, with mean rank in the Kruskal-Walls test of 16.63. VAT sequences combined with T2 TSE were able to reduce metal artifacts quite well, with mean rank in the Kruskal-Walls test of 15.19. The more optimal sequence for reducing metal artifacts is the SEMAC T2 TSE, where the sequence is able to reveal thin structures that are not visible in the T2 TSE and T2 TSE VAT sequences.
