    Nonvisualization of the gallbladder during ultrasound (cholecystosonography) accurately predicts gallbladder disease. Oral cholecystography is recommended for further diagnostic confirmation before surgical intervention.

    Area of Science:

    • Radiology
    • Gastroenterology
    • Diagnostic Imaging

    Background:

    • Gallbladder nonvisualization during cholecystosonography requires further investigation.
    • Previous studies suggest a correlation between nonvisualization and gallbladder pathology.

    Purpose of the Study:

    • To determine the diagnostic significance of gallbladder nonvisualization on cholecystosonography.
    • To assess the accuracy of sonography in predicting gallbladder disease.

    Main Methods:

    • Retrospective analysis of 25 patients with gallbladder nonvisualization on ultrasound.
    • Follow-up diagnostic procedures including intravenous cholangiography and surgical pathology.
    • Correlation of imaging findings with established pathoanatomic diagnoses.

    Main Results:

    • Gallbladder nonvisualization was highly predictive of gallbladder disease.
    • Of 24 patients with established diagnoses, 22 had diseased gallbladders with lumen obliteration (88% accuracy).
    • One patient had a nonvisualized but otherwise normal gallbladder.

    Conclusions:

    • Gallbladder nonvisualization on cholecystosonography is a significant indicator of underlying gallbladder pathology.
    • Oral cholecystography offers enhanced diagnostic accuracy for nonvisualized gallbladders, particularly when surgery is considered.
    • Sonographic nonvisualization demonstrates diagnostic significance comparable to oral cholecystography.
