A 55-yeаr-оld mаle with а high Bоdy Mass Index (BMI) is referred fоr an ultrasound to rule out acute cholecystitis. He has localized tenderness over the gallbladder. Sonographic Challenge:As you scan the gallbladder in the short axis (transverse plane), you notice significant reverberation artifacts—regularly spaced, linear echoes—originating from the abdominal wall and "bleeding" into the gallbladder lumen. This "clutter" makes the anterior wall appear thick and fuzzy, making it impossible to tell where the wall ends and the bile begins To ensure an accurate measurement of the anterior wall thickness (normal is < 3 mm) and clear the reverberation artifact from the gallbladder's lumen, which imaging combination is most effective?
