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

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
... 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.
