Area of Science:

  • Medical Imaging
  • Vascular Ultrasound
  • Abdominal Sonography

Background:

  • Color Flow Imaging (CFI) is a valuable ultrasound technique for visualizing blood flow in abdominal vessels.
  • Its applications include diagnosing liver disease complications, vascular abnormalities, and monitoring organ transplants.

Purpose of the Study:

  • To evaluate the diagnostic yield of CFI in abdominal vascular imaging.
  • To assess the impact of CFI on patient safety, particularly regarding biopsy procedures.

Main Methods:

  • CFI was applied to 205 patients previously examined by conventional sonography.
  • Data collected included additional vascular findings, unexpected results, and identification of risks before biopsy.

Main Results:

  • CFI identified 107 additional vascular findings in 205 patients.
  • 10.2% of these findings were unexpected, with 2.9% being serious unexpected findings.
  • CFI identified risks in 1.14% of patients before biopsy, and consequential use reduced liver tumor bleeding risk from 1.2% to 0.2%.

Conclusions:

  • CFI significantly increases diagnostic information in abdominal vascular imaging.
  • The routine use of CFI enhances patient safety by identifying and mitigating risks, especially for procedures like liver biopsies.
