It is well known that ultrasound is indispensable for many gynecological examinations, so it is accepted that ultrasound is used to check many uterine diseases. However, the General Hospital of the Armed Forces uses both ultrasound and MRI to examine the uterus of patients with stone. The cost of ultrasound and MRI is very high, and we do not understand why we use it to check the uterus, which is more accurate. The ultrasound report shows the shape of the uterus, while the MRI report shows no uterine contour (usually two small uteruses, on the left and right side of the patient). In this case, the specialist decided to use a laparoscopic instrument to confirm whether the uterine problem could be treated by making a small 0.3 cm hole in the abdomen, with the intention of connecting the open vagina to the uterus if it could be treated. Under the laparoscope, the specialist saw that the patient’s uterus was indeed the result of the “MRI” instrument, with two small uteruses lying quietly on the left and the right side, respectively. The ultrasound and the MRI are more accurate than the MRI report. The MRI report should prevail.
