Ultrasonography: reproductive tract - female

pequis

Introduction

  • An ultrasonic image is produced by the reflection of high-frequency sound waves at density interfaces between two tissues Ultrasonography: overview.
  • Fluid is an excellent medium for transmission of sound waves and fluid-filled structures appear black or anechoic on the ultrasonographic image.
  • Gas transmits little but produces severe attenuation of the sound beam.
  • Other tissues are seen as various shades of gray depending on their ability to reflect sound waves.
  • Ultrasonography is valuable in the evaluation of soft tissue pathology and the reproductive tract.
  • Trans-cutaneous and rectal routes can be used, depending on the area which is to be imaged.

Uses

Advantages

  • Non-invasive.
  • Portable.
  • Safe (providing care is taken in the rectum).
  • Inexpensive.
