Abstract

Objectives: Many patients with metallic objects in the head and neck region may require magnetic resonance imaging (MRI). The aim of this study was to assess the artifacts produced by different dental crown materials on ultrashort echo time (UTE) MRI. Materials and Methods: Cobalt-chromium (Co-Cr) and zirconia (Zr) crown and fixed bridges were included and embedded in agar gel. UTE sequence by 1.5T MRI was performed and the artifact area produced by these materials, were measured within the region of interest (ROI). Mean artifact areas were recorded. Results: Mean artifact area produced by Co-Cr and Zr was 140.055 mm2 and 102.349 mm2, respectively. Zr material produced less artifacts than metal restoration. It was stated that the amount of artifact increased as the number of elements increased. Conclusions: Co-Cr metal restorations have stronger effect than Zr material on UTE MRI. UTE sequence is useful in evaluating susceptibility artifacts from different materials. Knowing the amount of artifact produced by different materials will help to produce new materials that cause less artifact formation or to improve the properties of existing materials.

Özet

Amaç: Baş ve boyun bölgesinde metalik nesneler bulunan birçok hastada manyetik rezonans görüntüleme (MRG) gerekebilir. Bu çalışmanın amacı, ultrashort echo time (UTE) MRG'de farklı dental kron materyalleri tarafından üretilen artefaktları değerlendirmektir. Gereç ve Yöntemler: Kobalt-krom (Co-Cr) ve zirkonyum (Zr) kron ve sabit köprüler dahil edildi ve agar jele gömüldü. 1.5T MRG ile UTE sekansı yapıldı ve bu materyallerin ürettiği artefakt alanı, ilgilenilen bölge içinde ölçüldü. Ortalama artefakt alanları kaydedildi. Bulgular: Co-Cr ve Zr tarafından üretilen ortalama artefakt alanı sırasıyla 140.055 mm2 ve 102.349 mm2 idi. Zr materyali metal restorasyondan daha az artefakt üretti. Element sayısı arttıkça artefakt miktarının da arttığı belirtildi. Sonuçlar: Co-Cr metal restorasyonlar UTE MRI'da Zr materyalden daha güçlü etkiye sahiptir. UTE sekansı, farklı materyallerden duyarlılık artefaktlarının değerlendirilmesinde yararlıdır. Farklı materyallerin ürettiği artefakt miktarının bilinmesi, daha az artefakt oluşumuna neden olan yeni materyallerin üretilmesine veya mevcut materyallerin özelliklerinin iyileştirilmesine yardımcı olacaktır.
