Abstract：Objective: To investigate MRI features of fishbones in rabbit vitreous body. Methods: In 16 New Zealand healthy rabbits, fishbones were implanted into the right vitreous body, the size of fishbones were 0.15 to 0.2 mm in diameter and 1.5 to 3.5 mm in length. Take the left vitreous body as the nomal comparison. All cases underwent MRI, CT and ultrasound examination within 2 hours. Results: T1WI, T2WI, and SWI separately detected 4, 15, and 26 fishbones foreign body. The detected fishbones were dot or linear hypointense in T1WI, T2WI and SWI images, high density in CT, and strong echo of the light spots in sonogram. Conclusion: Fishbone foreign body in right vitreous body of rabbit had its characteristics in imaging, synthetic application is helpful to the detection and diagnosis of fishbones in rabbit vitreous body.
