3.0 t magnetom prisma system

To make 3D EM model of the beagle, the three-dimension (3D) magnetization-prepared rapid gradient-echo (MP-RAGE) images of the beagle, under sedation with Telazol (5 mg/kg i.m.) and xylazine (2 mg/kg i.m.), were acquired using a Siemens 3.0 T Magnetom Prisma system with a 32-channel head coil. The following exam parameters were used: a repetition time of 2300 ms with an echo time of 3.4 ms, a slice thickness of 0.5 mm without slice interval, the flip angle of 8°, the field of view (FOV) of 150 mm, and slice number per slab of 224.

MRI was obtained on a 3.0T MAGNETOM PRISMA system (Siemens) using a 20-channel phased array coil. For conventional MRI scans, the parameters for T1-weighted imaging were TR/TE = 410 ms/13 ms, respectively, and field of view (FOV) = 22 cm × 22 cm, the parameters for T2-weighted imaging were TR/TE = 3400 ms/100 ms, respectively, and FOV = 22 × 22 cm, and the parameters for T2-fluid-attenuated inversion recovery imaging were TR/TE = 12,000 ms/130 ms, respectively, and FOV = 22 × 22 cm. Additional MRI sequences included three-dimensional T1 magnetization-prepared rapid gradient echo (TR = 2,300 ms, TE = 2.4 ms, inversion time = 991 ms, bandwidth = 200 Hz, number of averages = 1, matrix size = 154 × 256, coronal section thickness = 1.2 mm, flip angle = 8°, acquisition time = 3:23 min).
