This exam is performed by the gynecologist in hospitals, imaging clinics or in the gynecological office, and can be performed by SUS, some he alth plans or in a private way.


What is it for

  • Suspicion or identification of lesions in the uterus, especially fibroids that are small benign tumors that develop slowly and can cause large bleeding and consequently anemia;
  • Differentiation of uterine polyps;
  • Investigation of abnormal uterine bleeding;
  • Evaluation of women with unexplained infertility;
