[Hystero-salpingo-contrast-sonography with 3-d-ultrasound -- a pilot study]

Area of Science:

• Reproductive medicine
• Medical imaging
• Gynecologic diagnostics

Background:

• Hystero-salpingo-contrast sonography (HyCoSy) is a sensitive method for assessing tubal patency.
• Conventional HyCoSy cannot fully replace diagnostic laparoscopy with hysteroscopy.
• Three-dimensional (3D) sonography offers advanced imaging capabilities that may reduce the need for invasive procedures.

Purpose of the Study:

• To evaluate the feasibility of HyCoSy using 3D and 3D-Doppler sonography.
• To assess the diagnostic accuracy of 3D imaging in visualizing Fallopian tubes compared to conventional methods.

Main Methods:

• A prospective pilot study involving 21 patients undergoing conventional (2D) HyCoSy.
• Subsequent 3D-ultrasound imaging was performed, with 3D-Doppler-HyCoSy in five patients.
• Laparoscopy with blue dye was conducted immediately after ultrasound for comparison.

Main Results:

• Assessment of 42 Fallopian tubes revealed varying visibility on 2D and 3D ultrasound.
• 3D-Doppler-HyCoSy demonstrated excellent assessment in 80% of tubes, improving accuracy.
• Uterine cavity assessment was excellent in most patients with both 2D and 3D HyCoSy.

Conclusions:

• 3D-ultrasound can visualize Fallopian tubes in detail but does not enhance HyCoSy's diagnostic power alone.
• 3D-Doppler-HyCoSy appears to improve the accuracy of tubal patency assessment.
• Further research may explore the role of 3D-Doppler-HyCoSy in reducing invasive diagnostic procedures.
