Summary
Transvaginal sonography offers superior imaging resolution by avoiding interfering structures. This review details its techniques, compares transducers, and discusses safety for fetal imaging.
Area of Science:
- Medical imaging
- Gynecologic ultrasonography
- Obstetric ultrasonography
Background:
- Transabdominal sonography is limited by intervening structures.
- Transvaginal sonography offers potential for improved image quality.
Purpose of the Study:
- To describe and compare transvaginal and transabdominal transducers.
- To outline sagittal and coronal views in transvaginal sonography.
- To discuss advantages, disadvantages, and safety of transvaginal sonography.
Main Methods:
- Description and comparison of transvaginal and transabdominal transducer technology.
- Explanation of imaging planes (sagittal, coronal) specific to transvaginal approach.
Main Results:
- Transvaginal sonography provides enhanced resolution and image clarity.
- Identification of specific advantages and disadvantages compared to transabdominal approach.
- Consideration of safety implications due to reduced attenuation path to the fetus.
Conclusions:
- Transvaginal sonography is a valuable tool for improved gynecologic and obstetric imaging.
- Understanding its technical aspects and safety profile is crucial for effective clinical application.
