High resolution 3D magnetic resonance imaging of the visceral organs in chicken (Gallus domesticus) by 3 Tesla MR unit and 15-channel transmit coil

Öz:

Kuşlarda modern görüntüleme teknikleri üzerine yürütülmüş çalışmalar kısıtlıdır ve özellikle klinisyenler için yetersiz kalmaktadır. Manyetik rezonans (MR) görüntüleme (MRG), memelilerde olduğu gibi kanatlı hastalıklarının tanı ve tedavisi için de elverişli bir yöntemdir. Bu çalışmada; 2 horoz ve 2 tavuğun vücudu 3 Tesla MRG cihazı ile T1, T2 ve proton-dansite ağırlıklı (A) sekanslar ve 15-kanallı alıcı-verici koyil kullanılarak, 3 boyutlu (3B) olarak değerlendirildi. MRG işlemi sonrasında; görüntüleme işlemindeki pozisyonu ile aynı konumda dondurulmuş vücutlar, MR görüntüleri ile eşleşen bölümlerden dilimlendi. Anatomik yapılar, MR görüntüleri ve kadavra bölümlerinde tespit edildi ve işaretlendi. Daha sonra, MR görüntülerine 3B multiplanar rekonstrüksiyon uygulandı. T1A görüntülerde, anatomik detaylar yüksek geometrik çözünürlük nedeniyle daha iyi gözlendi. T2A görüntülerde, doku kontrastı farkları ve sıvı içerikli yapılar açıkça tespit edildi. 3B sekanslardan elde edilen oblik planlı ve maksimum yoğunluk gösteren renkli reformat görüntülerde, anatomik ayrıntılar daha net bir şekilde belirlendi ve dokular yüksek çözünürlük ile birbirinden daha kolay bir şekilde ayırt edildi. Bu çalışmadaki amaç; dokuların görüntüleme özelliklerini tanımlamak ve kuşların vücut yapılarının MRGdeki anatomisine genel bir bakış sağlamaktı. Bunların yanı sıra, kanatlılarda MRG için en uygun sekanslarda tayin edildi.

Tavukta (Gallus domesticus) visseral organların 3 Tesla manyetik rezonans ünitesi ve 15-kanallı coil ile yüksek rezolüsyonlu 3B görüntülenmesi

Öz:

Imaging studies conducted on the modern imaging techniques for birds are limited and probably insufficient for the clinicians. As in mammals, magnetic resonance (MR) imaging (MRI) can be used as a convenient method for the diagnosis and treatment of the avian diseases. In this study, the whole bodies of 2 male and 2 female chickens were imaged by a 3 Tesla superconductive magnet and 15-channel transmit-receive birdcage coil. After acquisition of three dimensional (3D) T1, T2 and proton density weighted (W) MR images; bodies were frozen in same position with the one in imaging process and sliced from matching sections with original and reformatted MR images. Anatomic structures were identified and labeled in both MR images and cadaver sections. After that, 3D multiplanar reconstruction was performed on the MR images. On T1W images, it was observed that the anatomical details were superior due to the high geometric resolution. On T2W images, the tissue contrast differences and fluid filled ducts were clearly detected. On three orthogonal and oblique planes reformatted and maximum intensity projection (MIP) colored images, the anatomic details were more clearly determined and the tissues were more easily distinguished from each other with high geometric and contrast resolution. The aim of this study was to define MRI features of the tissues, and to provide an overview of MRI anatomy of the avian body structures. Besides, the most convenient sequences for the avian MRI were also designated.
