Duplex sonography noninvasively assesses blood flow in vessels and organs. This imaging technique is practical for diagnosing conditions like portal hypertension and arterial blockages.

Area of Science:

  • Vascular imaging
  • Medical diagnostics
  • Ultrasound technology

Background:

  • Noninvasive assessment of blood flow is crucial for diagnosing various vascular and organ conditions.
  • Conventional and colour-coded duplex sonography offer practical methods for evaluating blood flow.
  • Existing methods are effective in identifying specific pathologies like portal hypertension and arterial stenosis.

Purpose of the Study:

  • To evaluate the utility of duplex sonography in examining blood flow within vessels and organs.
  • To highlight the practicability of duplex sonography in diagnosing specific clinical conditions.
  • To explore the potential future applications of duplex sonography in medical diagnostics.

Main Methods:

  • Utilizing conventional duplex sonography for blood flow assessment.

  • Employing colour-coded duplex sonography for enhanced visualization.
  • Applying these noninvasive techniques to examine portal hypertension, portal thrombosis, Budd-Chiari syndrome, and mesenteric artery stenosis/occlusion.

    • Main Results:

    • Duplex sonography effectively examines blood flow in vessels and organs noninvasively.
    • The method is highly practicable for diagnosing portal hypertension, portal thrombosis, and Budd-Chiari syndrome.
    • Stenosis and occlusion of the coeliac trunk and superior mesenteric artery can be reliably detected.

    Conclusions:

    • Duplex sonography is a valuable noninvasive tool for vascular and organ blood flow assessment.
    • Its practicability is demonstrated in managing conditions such as portal hypertension and mesenteric artery diseases.
    • Future applications may include the differential diagnosis of space-occupying lesions, though quantitative measurements are primarily for research.
