Uterine fibroids can be detected by ultrasound, and it can also clearly indicate the size of the fibroids and the exact location of the fibroids. Fibroids are classified as interstitial, submucosal and subplasmic fibroids. Patients with submucosal fibroids may have heavy menstrual periods and present with decreased hematocrit and anemia. Subplasmalemmal fibroids will be relatively less affected. Interstitial myomas tend to appear as masses of echogenicity within the muscle layer. The echogenicity of uterine fibroids is clear and can be solitary or multiple, and they tend to have hypoechoic or less uniform hypoechoic changes within them. On color Doppler flow, striated flow signals can be seen both peripherally and internally in the myoma.
