Title: Diagnostic value of hepatic perfusion disorders in acute cholecystitus
Abstract: Objective To discuss the diagnostic value of multi-layer screw CT enhancement scanning in hepatic perfusion disorder in acute cholecystitus and to analyze the factors that resulted in the occurrence of this disorder. Methods The data of 26 patients with acute cholecystitus,who firstly received plain CT and,subsequently,underwent enhanced CTment scanning,were collected in this work.The scanning scope included the entire liver and gallbladder.The thickness of layer for scanning was 5.0-7.5 mm,the contrast agent was iohexol that was injected into body with a dosage of 80-100 ml and a speed of 3.0-3.5 ml/s.The delay time was that the artery time retarded 24-28 s and the portal vein time retarded 70-75 s. Results Of these 26 patients with acute cholecystitus,24 appeared the spot laminated shape,the laminated shape in the artery time and half ring-like exceptionally strengthening.The abnormally strengthening scope confined to liver tissue adjacent to gallbladder.However,perfusion disorder disappeared in the vein time. Conclusion The inflammatory infiltration and hyperemia around the liver tissues in acute cholecystitus are the pathological foundation for hepatic perfusion disorder.The hepatic perfusion disorder in liver tissues around the gallbladder is an important CT sign of acute cholecystitus,which possesses great value in the diagnosis of acute cholecystitus.
