Fibroid Specialists, Depending on your situation, there are a variety of ways to diagnose uterine fibroids, but a preliminary pelvic ultrasound scan is typically required. An MRI is the best tool for assessing the types, sizes, and characteristics of fibroids. If abnormal bleeding has any other underlying causes, such as adenomyosis, they can be found using this imaging technique. To guarantee that every patient receives the best possible care and the best results, our highly trained specialist orders an MRI on every patient.
