Jaundice is the end result of myriad causes, which makes the role of imaging in this setting particularly challenging. In the United States, the most common causes of all types of jaundice fall into four categories including hepatitis, alcoholic liver disease, blockage of the common bile duct by a gallstone or tumor, and toxic reaction to a drug or medicinal herb. Clinically, differentiating between the various potential etiologies of jaundice requires a detailed history, targeted physical examination, and pertinent laboratory studies, the results of which allow the physician to categorize the type of jaundice into mechanical or nonmechanical causes. Imaging modalities used to evaluate the jaundiced patient (all etiologies) include abdominal ultrasound (US), CT, MR cholangiopancreatography, endoscopic retrograde cholangiopancreatography and endoscopic US. The American College of Radiology Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed annually by a multidisciplinary expert panel. The guideline development and revision include an extensive analysis of current medical literature from peer reviewed journals and the application of well-established methodologies (RAND/UCLA Appropriateness Method and Grading of Recommendations Assessment, Development, and Evaluation or GRADE) to rate the appropriateness of imaging and treatment procedures for specific clinical scenarios. In those instances where evidence is lacking or equivocal, expert opinion may supplement the available evidence to recommend imaging or treatment.
黄疸是多种病因导致的最终结果,这使得影像学在这种情况下的作用极具挑战性。在美国,各类黄疸最常见的病因可分为四类,包括肝炎、酒精性肝病、胆结石或肿瘤导致的胆总管梗阻,以及对药物或草药的毒性反应。临床上,区分黄疸的各种潜在病因需要详细的病史、针对性的体格检查和相关实验室检查,这些检查结果可让医生将黄疸类型归类为机械性或非机械性病因。用于评估黄疸患者(所有病因)的影像学检查方法包括腹部超声(US)、CT、磁共振胰胆管造影、内镜逆行胰胆管造影和内镜超声。美国放射学会适宜性标准是针对特定临床情况的循证指南,由多学科专家小组每年进行审查。指南的制定和修订包括对同行评审期刊上的当前医学文献进行广泛分析,并应用成熟的方法(兰德/加州大学洛杉矶分校适宜性方法以及推荐分级评估、制定与评价或GRADE)来评估特定临床场景下影像学检查和治疗程序的适宜性。在缺乏证据或证据不明确的情况下,专家意见可补充现有证据以推荐影像学检查或治疗。
