Over the past decade, computed tomographic (CT) urography has emerged as the primary imaging modality for evaluating the urinary tract in various clinical settings, including the initial workup of hematuria. With the widespread implementation of CT urography, it is critical for radiologists to understand normal ureteral anatomy and the varied appearance of pathologic ureteral conditions at CT urography. Pathologic findings at CT urography include congenital abnormalities, filling defects, dilatation, narrowing, and deviations in course. These abnormalities are reviewed, along with the indications for CT urography, current imaging protocols with specific techniques for optimal evaluation of the ureter, and dose reduction strategies.
在过去十年中，计算机断层扫描（CT）尿路造影已成为评估各种临床情况下尿路的主要成像方式，包括血尿的初步检查。随着CT尿路造影的广泛应用，放射科医生了解正常输尿管解剖结构以及CT尿路造影中病理性输尿管情况的各种表现至关重要。CT尿路造影的病理表现包括先天性异常、充盈缺损、扩张、狭窄和走行偏差。本文将对这些异常情况进行综述，同时介绍CT尿路造影的适应证、用于输尿管最佳评估的特定技术的当前成像方案以及剂量降低策略。
