ObjectiveTo improve knowledge of MRI characteristics of uterus bicornis, understand its MRI diagnosis features, and grasp the precautions of its MRI inspection. MethodsClinical manifestation and image examination results of 7 patients with uterus bicornis were analyzed. Philips 1.5T MRI scanner with abdominal coil was used to scan, and scanning sequence set as coronal and axial T2WI, T1WI and T2WISPAIR, sagittal T1WI and T2WISPAIR. ResultsOf 7 patients with uterine fibroids, 2 cases were complicated with uterine myoma (including 1 significantly increased uterine and 1 adenomyosis), 2 bilateral ovarian cysts, and 3 hydrosalpinx (2 on the left, 1 one the right, and 1 placenta residual cavity on left side after delivery). MRI image of uterus bicornis showed that: in the position horizontally parallel to uterus cavity, the bottom of the uterus concaved, and uterine was divide into the two symmetrical uterus in a shape of doublehorn connected to one cervix; while coronal image was featured as isolated dotlike change, T1WI even signal, and T2WI high signal. ConclusionMRI examination can better display the two corners of uterus bicornis and confirm the diagnosis. Its image is clear, intuitive, and easy to understand. In addition, it can clearly show the endometrium, uterine wall, and ectopic lesions, without radiation. It is indicated that MRI examination is the primary option for patients with clinically suspected uterine malformations.
