Abstract

The purpose of the study was to scan the brain and related structures in sheep with high-resolution magnetic resonanceimaging (MRI) and three-dimensional (3D) multiplanar reconstruction for defining the anatomical regions. Six adult sheep, three ofsix were male and three of six were female used as cadaver, were utilized in this research. Heads were scanned at 3 Tesla SiemensMagnetom Spin-Echo MRI devices using the human head coil. The processes were acquired in both T1 and T2 weighted slices andwere reconstructed by using Leonardo workstation. The cranioencephalic structures and anatomical details were defined and labeledin all slice of 3 planes that were obtained 1 mm thickness sequential images in sagittal, frontal, and transversal planes. According tothe MRI measurements obtained intracranially from the brain, the average value of length, height, and width of the brain were 87.1 ±0.3, 46.8 ± 0.7, and 62.2 ± 0.4 mm, respectively. It was observed that in T1 weighted images were more effective to identify deep brainstructures and anatomical details. On 3D reconstructed images obtained from the study can be used as a reference in head and brainMR scans in multidisciplinary studies where sheep are used as animal models.

Özet

Bu çalışmada, koyun beyni ve beyin çevresindeki anatomik yapıların, yüksek çözünürlüklü manyetik rezonans ile görüntülenmesi ve 3 boyutlu (3B) multiplanar rekonstruksiyonu ile bölge anatomisinin özelliklerinin belirlenmesi amaçlandı. Araştırma için 3 erkek, 3 dişi toplam 6 yetişkin koyun kullanıldı. Tüm kafalar 3 Tesla Siemens Magnetom Spin-echo manyetik rezonans görüntüleme cihazı ile insan kafa koili kullanılarak tarandı. Tarama işlemi hem T1, hem de T2-ağırlıklı olarak yapıldı ve Leonardo workstation kullanılarak rekonstrüksiyonu yapıldı. Sagittal, frontal ve transversal düzlemlerde alınan yaklaşık 1 mm kalınlığındaki ardışık kesit görüntülerinin üzerinde kafa yapıları ve anatomik detaylar üç düzlemde ve her kesit üzerinde tanımlanarak işaretlendi. Kesit görüntüleri üzerinden yapılan kafa içi ölçümlerde encephalon’un ortalama uzunluğu, yüksekliği ve genişliği sırasıyla 87.1 ± 0.3, 46.8 ± 0.7 ve 62.2 ± 0.4 mm olarak ölçüldü. T1 ağırlıklı görüntülerin, derin beyin yapılarının ve anatomik detayların tanımlanmasında daha etkili olduğu görülmüştür. Hayvan modeli olarak koyunun kullanıldığı multidisipliner çalışmalarda, 3B rekonstrüksiyon ile elde edilen görüntülerin, baş ve beyin MR taramalarında referans olarak kullanılabilir.
