A revised system for mediastinal mass differentiation has been developed and used at the Veterans Administration Medical Center, San Diego, and University Hospital of the University of California, San Diego. Contrast medium infusion or bolus computed tomography of the entire mediastinum is obtained, except when the mass is probably a thyroid mass (123I scan then obtained first) or an esophageal mass (barium swallow evaluation then obtained first). Next computed tomography density is determined, and only subsequently are masses of similar density subdivided by location. Further differentiation is based on computed tomography imaging parameters. A new algorithm for evaluation of mediastinal masses has resulted from use of this system. The system has been shown to increase specificity of differential diagnosis and to result in increased efficiency of evaluation of patients with mediastinal masses.
一种用于纵隔肿块鉴别诊断的改良系统已被研发出来，并在圣地亚哥退伍军人事务医疗中心以及加利福尼亚大学圣地亚哥分校大学医院投入使用。除肿块可能为甲状腺肿块（此时先进行123I扫描）或食管肿块（此时先进行吞钡评估）外，需对整个纵隔进行造影剂注入或团注计算机断层扫描。接下来确定计算机断层扫描密度，只有在随后才根据位置对密度相似的肿块进行细分。进一步的鉴别诊断基于计算机断层扫描成像参数。使用该系统产生了一种评估纵隔肿块的新算法。该系统已被证明可提高鉴别诊断的特异性，并提高纵隔肿块患者评估的效率。
