Contrast-enhanced power Doppler US: is it useful in the differentiation of gallbladder disease?
Thirteen patients with gallbladder disease underwent power Doppler ultrasound (PDUS) before and after microbubble contrast agent injection. Lesion and liver bed vascularity was evaluated. Pathological diagnoses in nine patients were two acute cholecystitis, four chronic inflammation, one adenoma and two adenocarcinoma. Two cases of cancer were included on clinical and radiological findings. Two cases were excluded because no pathologic diagnosis was available. Liver bed hyperemia was noted only in acute cholecystitis. Contrast-enhanced PDUS was superior to nonenhanced PDUS in the demonstration of vascularity of gallbladder diseases. However, contrast-enhanced PDUS has limited value in the differentiation.
