Acute cholecystitis is a relatively common clinical entity characterized histopathologically by obstruction of the cystic duct due to either edema or stone or both. Thorough clinical assessment and selection of the appropriate diagnostic tests are crucial in making an early diagnosis before surgical treatment. Many diagnostic tests are available for imaging the gallbladder. Hepatobiliary imaging using technetium Tc 99m IDA is the test of choice to either exclude or confirm the diagnosis of acute cholecystitis and it carries a discriminating power greater than that of cholecystography or ultrasonography. In most patients the exclusion of the diagnosis of acute cholecystitis can be made as early as 30 minutes and the confirmation within three hours. The confirmation of acute cholecystitis by radionuclide imaging obviates the need for either cholecystography or ultrasonography.
急性胆囊炎是一种相对常见的临床病症，其组织病理学特征为胆囊管因水肿或结石或两者共同作用而阻塞。在进行手术治疗前，全面的临床评估和选择合适的诊断测试对于早期诊断至关重要。有多种诊断测试可用于胆囊成像。使用锝 Tc 99m IDA 进行肝胆成像，是排除或确诊急性胆囊炎的首选测试，其鉴别能力高于胆囊造影或超声检查。在大多数患者中，最早可在 30 分钟内排除急性胆囊炎的诊断，3 小时内确诊。通过放射性核素成像确诊急性胆囊炎可避免进行胆囊造影或超声检查。
