n. radiological examination of the uterus and Fallopian tubes. A radiopaque contrast material is injected through a catheter placed in the uterine cavity and the flow is then observed with X-rays. The technique is used to look for patency of the Fallopian tubes in cases of infertility, or for any uterine anomalies or mass. See also sonohysterography.
n. an examination of the uterus and Fallopian tubes using ultrasound rather than X-rays (as in *hysterosalphingography). In saline infusion sonohysterography (SIS) evaluation of the endometrial cavity is augmented by the use of saline, which distends the uterine cavity separating the two layers of endometrium and creating a contrast. This can help identify intracavitary lesions (e.g. submucous *fibroids) and determine the amount of cavity distortion.... sonohysterography
