Aim Our goal was to demonstrate the feasibility of pelvic magnetic resonance imaging ( MRI ) in the ewe. Material and Methods Two ewes underwent a pelvic 3 T esla MRI scan, under light anesthesia, with T 2‐weighted fast spin‐echo images and T 1‐weighted spoiled gradient‐echo images. Multiplan T 1 weighted images were also obtained after the intravenous injection of a contrast product. One ewe was anestrous and the other one had undergone ovarian stimulation. Results No incident occurred during the examination. Both the uterus (with two horns) and the ovaries were identified. The intensity of the endometrial, myometrial and ovarian signals was similar to that encountered in women. The uterus and ovaries could be enhanced in both cases. Pelvic vasculature was also studied. In the case of hormonal stimulation, the endometrium was thicker, follicular growth was identified and enhancement seemed greater. Conclusion MRI in the ewe is feasible and could be helpful in experimental gynecologic research, especially in uterus transplantation.
