Heavy or irregular menstruations cause difficulties to healthy women, affecting the quality of life. An accurate diagnosis of the cause of menstrual problems is very important when planning an effective treatment. Ultrasound examination is the best and easiest way to diagnose the most common causes of particularly heavy menstruations such as uterine fibroids and adenomyosis. When women are diagnosed with uterine fibroids, the detection of their exact location and size is of great importance. The mapping of fibroids can be sometimes complicated, but it is facilitated by the use of modern ultrasound technology.
