The main focuses of this group are:
  • Abdominal and Transvaginal ultrasound: Abdominal and transvaginal ultrasound have a high predictive value in both obstetrics and gynecology investigatins. Gynecologic ultrasonography refers to the application of ultrasound to assess the female pelvic organs. It also forms a part of routine clinical investigations of women with history of gynechologic disorders, infertility, recurrent miscarriage and early preterm labor and before and during IVF/ICSI. Two-dimensional transvaginal ultrasound (2DUS) and Doppler ultrasound has a reliable diagnostic value in assessment of female pelvic organs.
  • 3D/4D Ultrasonography (3DUS): Detection of uterine abnormalities (acquired and congenital uterine abnormalities) has been the focus of research in gynecology recently. The congenital uterine abnormalities may have an important role in subinfertility, implantation failure and outcome of pregnancy. 3DUS has recently become the mandatory step in the classifying MDAs since there is a high degree of concordance between 3DUS and MRI in the diagnosis of uterine malformation. In addition, 3D recently has become available for endometrial volume measurement. Ultrasonographic assessment of the endometrium is an important investigative tool in the assessment of endometrial receptivity. Endometrial volume is a useful criterion in predicting embryo implantation success and pregnancy rate in patients undergoing in-vitro-fertilization (IVF).

  • Study uterine abnormalities using 3D/4D: Sonohysterography consists of ultrasonographic imaging of the uterus, using real-time ultrasonography during injection of sterile saline into the uterine cavity. The goal of sonohysterography is to detect intrauterine lesions ( polype, leiomyomas, hyperplasia, ahhesions…)and congenital uterine abnormalities(septate, bicornuate,unicornuate…) by real -time ultrasonography. Sonohysterography associated with three-dimensional ultrasonography (3DUS) which is performed in this department is a non-invasive, cost _effective, outpatient diagnostic modality, which enables a detailed assessment of uterine morphology .The appearance of fluid surrounding the fimbria, turbulence in the periadnexae and accumulation of fluid in cul-de-sac were considered evidence of tubal patency.

  • Prenatal ultrasonographic screening of fetal abnormalities: Prenatal screening is testing for diseases in a fetus before it is born. The aim is to detect birth defects such as neural tube defects, Down syndrome, chromosome abnormalities and so on. An ultrasound screening in the first, second and third trimester can rule out potential for abnormalities. Nuchal translucency measurement is a common screening test at the first trimester scans.
