Computed tomography (CT) is widely recognized as a part of the routine preoperative staging in patients with esophageal carcinoma. Applying a tailored technique, CT criteria of transmural growth and infiltration of adjacent structures are highly accurate for estimating resectability. The size-based assessment of mediastinal and abdominal lymph nodes is usually reported with low sensitivity and specificity. Spiral technology (spiral CT) increases image quality by a reduction of artifacts due to respiratory motion or cardiac pulsation, higher anatomic detail, and peak vascular opacification throughout the entire examination. Thus, an improvement of diagnostic accuracy in the staging of esophageal carcinoma can be expected. Its targeted application and a comparison with the conventional technique are presented.
计算机断层扫描（CT）被广泛认为是食管癌患者术前常规分期的一部分。采用定制技术时，CT判断肿瘤透壁生长及邻近结构浸润的标准在评估可切除性方面具有很高的准确性。基于大小对纵隔和腹部淋巴结进行评估，其敏感性和特异性通常较低。螺旋技术（螺旋CT）通过减少呼吸运动或心脏搏动产生的伪影、提高解剖细节以及在整个检查过程中实现血管造影剂峰值显影，提高了图像质量。因此，有望提高食管癌分期的诊断准确性。本文介绍了其靶向应用以及与传统技术的比较。
