The aim of this study was to investigate the role of Power Doppler ultrasonography in diagnosing acute cholecystitis and differentiating acute from chronic cholecystitis. In one hundred twenty patients with acute right upper quadrant pain or clinically suspected cholecystitis, gallbladder wall vascularity underwent color Doppler ultrasonography and Power Doppler ultrasonography as an adjunct to gray-scale ultrasonography. Imaging findings were compared with pathologic findings in the 48 patients who underwent cholecystectomy. In histopathologic examinations of the operated 48 patients, 23 patients had acute cholecystitis, 25 patients had chronic cholecystitis. With power Doppler ultrasonography, 22 (95%) of 23 patients with acute cholecystitis had hypervascularity in gallbladder wall. Sensitivity and specificity of Power Doppler ultrasonography for revealing acute cholecystitis were 95% and 100%, respectively. As a result, Power Doppler ultrasonography is a very sensitive method for diagnosing acute cholecystitis and differentiating it from chronic cholecystitis. It should be routinely performed in patients with suspected cholecystitis to improve the diagnostic capabilities of gray-scale ultrasonography.}, number={1}, publisher={Ege University}
