30 lis 2023 · Diagnostic imaging modalities for AC include ultrasound (US), computed tomography (CT), or hepatobiliary iminodiacetic acid (HIDA) scan [3]. A 2012 meta-analysis reported that the HIDA scan had the highest diagnostic accuracy for AC [4].
15 paź 2017 · Typical ultrasound images of acute cholecystitis. (a) Pericholecystic fluid. Pericholecystic fluid is demonstrated to the left side of the gallbladder.
