Objectives: To evaluate the effects of syngo WARP on reducing metal artefacts from dental materials. Methods: Short tau inversion recovery (STIR) with syngo WARP [a dedicated metal artefact reduction sequence in combination with view-angle-tilting (VAT)] was performed using phantoms of three dental alloys: cobalt–chromium (Co–Cr), nickel–chromium (Ni–Cr), and titanium (Ti). Artefact volumes and reduction ratios of black, white and overall artefacts in the standard STIR and syngo WARP images with several different parameter settings were quantified according to standards of the American Society for Testing and Materials F2119-07. In all sequences, the artefact volumes and reduction ratios were compared. The modulation transfer function (MTF) and contrast-to-noise ratio (CNR) were also measured for evaluation of image quality. Results: In standard STIR, the overall artefact volume of Co–Cr was markedly larger than those of Ni–Cr and Ti. All types of artefacts tended to be reduced with increasing receiver bandwidth (rBW) and VAT. The effect of artefact reduction tended to be more obvious in the axial plane than in the sagittal plane. Compared with standard STIR, syngo WARP with a matrix of 384 × 384, receiver bandwidth of 620 Hz/pixel, and VAT of 100 % in the axial plane obtained reduction effects of 30 % (white artefacts), 45 % (black artefacts), and 38 % (overall artefacts) although MTF and CNR decreased by 30 and 22 % compared with those of standard STIR, respectively. Conclusions: syngo WARP for STIR can effectively reduce metal artefacts from dental materials.

Backgrounds: Genu MRI examination, according to Moeller (2003) and Westbrook (2008), was done by one fat supression technique in every slice. Radiology Installation of PAU dr.S.Hardjolukito Yogyakarta Hospital used two types of fat suppression technique those are STIR and T2-SPAIR. This study aims to find out the image differences between STIR and T2-SPAIR and to determine the fat suppresion technique that produces better image information of axial genu MR imaging.Methods: This research was a quantitative research with an experimental approach. Subjects of this study was image of axial genu MRI examination between STIR and T2- SPAIR in Radiology Installation of PAU dr.S.Hardjolukito Yogyakarta Hospital. The axial genu MR imaging STIR and T2-SPAIR assessed by three radiology phisicians using questioner. Data were statistically analyzed using Wilcoxon Sign Test.Results: The results showed a significant difference in all categories of assessment criteria between STIR and T2-SPAIR. In this study, the T2-SPAIR fat suppression technique produced better image information than STIR, whereas T2-SPAIR fat suppress signals was stronger than STIR.Conclusion: T2-SPAIR fat suppress signal was stronger than STIR that showed better image information and shorter time scanning
