Duplex Doppler scanning in the pelvis and abdomen

Area of Science:

• Medical Imaging
• Vascular Ultrasound

Background:

• Doppler ultrasound is increasingly utilized for abdominal and pelvic assessments.
• Signal interpretation can be qualitative, semiqualitative, or quantitative.

Purpose of the Study:

• To describe normal Doppler findings in abdominal and pelvic vessels.
• To highlight the diagnostic applications of Doppler ultrasound in various pathologies.

Main Methods:

• Review of Doppler ultrasound applications in abdominal and pelvic imaging.
• Description of normal time-velocity spectra in major vessels.
• Analysis of Doppler signal characteristics in pathological conditions.

Main Results:

• Doppler ultrasound can document portal venous system flow and identify abnormalities.
• It provides crucial perfusion data for liver transplantation.
• It is effective in assessing renal vessels, including thrombosis, stenosis, and transplant viability.
• Pelvic applications include monitoring ovulation, assessing bowel viability, impotence, and testicular torsion.
• Tumor vascularity can be characterized by Doppler signals.

Conclusions:

• Doppler ultrasound is a versatile tool with expanding applications in abdominal and pelvic diagnostics.
• It enhances the evaluation of vascular structures and organ perfusion.
• Further research is warranted for characterizing tumor blood flow using Doppler ultrasound.
