Merkepte (Equus asinus) hava keseleri (diverticulum tubae auditivae) ve ilişkili yapıların manyetikrezonans ile görüntülenmesi
Abstract
Çalışmada 4 adet yetişkin merkep başında hava keseleri ve ilişkili oldukları yapıların (kemikler, kaslar, tükrük bezleri, damarlar ve sinirler gibi…) anatomisi detaylı olarak incelendi. Bu amaçla insan vücut koili içerisinde, 1,5 tesla gücündeki magnet aracılığıyla alınmış, 5 mm kalınlığındaki transversal kesitler kullanıldı. Elde edilen görüntüler mükemmel düzeyde detay sağladı ve tüm slaytlardaki ilişkili yapılar belirlendi. Hava keseleri ve kemik korteksi çok düşük sinyal yoğunluğuyla taranırken, kaslar hafif hipointens, tükrük bezleri ise hafif hiperintens özellikte tarandı. Bu çalışma ile sunulan verilerin, klinik uygulamalarda başta hava kesesi hastalıklarının tanısı olmak üzere, hava keseleri ve ilişkili oldukları yapılar için, MR görüntülerinin değerlendirilmesinde referans olarak kullanılacağı düşünülmektedir

Magnetic resonance imaging of the guttural pouch (diverticulum tubae auditivae) and its related structures in donkey (Equus asinus)
Abstract
Anatomy of the guttural pouches and their associated structures such as bones, muscles, salivary glands, vessels and nerves were examined in detail in 4 adult donkey heads by magnetic resonance imaging (MRI). The protocol was performed using a superconducting magnet operating at a field strenght of 1,5 Tesla in 5 mm thickness transversal sections in human body coil. The obtained images provided excellent detail, so the relevant anatomic structures were described in whole slices. The pouch and cortical bone were scanned very low signal intensity, the muscles were slightly hypointense and the salivary glands were slightly hyperintense signals. Presented informations in this study will serve as a reference data to review MRI of the guttural pouch and its associated structures in clinical applications especially in the diagnosis of the guttural pouch diseases
