Summary
Sonography accurately differentiates ascites fluid types. Grade I echogenicity reliably identifies transudative ascites, while Grade II or higher suggests exudative collections, aiding clinical diagnosis.
Area of Science:
- Medical Imaging
- Gastroenterology
- Diagnostic Ultrasound
Background:
- Ascites diagnosis requires differentiating between transudative and exudative fluid.
- Sonographic assessment of ascites echogenicity can potentially aid this differentiation.
Purpose of the Study:
- To evaluate the accuracy of real-time sonography in distinguishing between exudative and transudative ascites.
- To correlate ascites echogenicity grades with fluid characteristics determined by diagnostic aspiration.
Main Methods:
- Real-time sonography was performed on 52 patients with ascites.
- Ascites echogenicity was graded I, II, and III relative to normal abdominal viscera.
- Sonographic grades were compared with results from diagnostic fluid aspiration.
Main Results:
- All 28 transudative ascites cases showed Grade I echogenicity.
- Only 3 of 21 exudative ascites cases presented with Grade I echogenicity.
- Grade I echogenicity demonstrated 92.32% sensitivity and 100% specificity for transudates.
Conclusions:
- Sonographic Grade I echogenicity is highly specific for transudative ascites.
- Higher echogenicity grades (II or III) strongly indicate exudative ascites.
- Ultrasound echogenicity is a valuable, non-invasive tool for ascites fluid characterization.
