The classic appearance of the echo-poor fibroid uterus occurs in less than one-third of leiomyomata uteri. The ongoing manifestations of the various types of internal degeneration produce a picture of diffuse or focal medium-amplitude internal echoes with increased through transmission. Calcification of fibroids results in irregular high-amplitude echoes or a ringlike echo pattern which must not be mistaken for a fetal head. The combination of wide dynamic range, gray scale scanning, and high-resolution real-time sonography optimizes the diagnosis of the fibroid uterus.
低回声子宫肌瘤的典型表现见于不到三分之一的子宫平滑肌瘤。各种类型内部变性的持续表现产生弥漫性或局灶性中等幅度内部回声且透声增加的图像。肌瘤钙化导致不规则高幅度回声或环状回声模式，切不可将其误认为胎儿头部。宽动态范围、灰阶扫描和高分辨率实时超声检查相结合，可优化子宫肌瘤的诊断。
