Plain-film tomography is a quick, accurate, and inexpensive procedure that is valuable for the evaluation of two common problems in chest radiology--the solitary pulmonary nodule and the hilus that is questionably abnormal. An accurate diagnosis can be made in most patients with a solitary pulmonary nodule so that appropriate management can be undertaken. If the diagnosis of an indeterminate nodule is made, further evaluation with computed tomography, transthoracic needle aspiration biopsy, surgery, or careful radiographic follow-up can be suggested. Hilar tomography can determine whether the appearance of the hilus on the chest radiograph is due to prominent but normal vessels, an enlarged pulmonary artery, enlarged hilar lymph nodes, or a pulmonary mass.
平片体层摄影是一种快速、准确且经济的检查方法，对于评估胸部放射学中的两个常见问题——孤立性肺结节和可疑异常的肺门，具有重要价值。大多数孤立性肺结节患者都能做出准确诊断，从而进行适当的处理。如果诊断为不明确的结节，可以建议进一步采用计算机断层扫描、经胸针吸活检、手术或仔细的影像学随访进行评估。肺门体层摄影可以确定胸部X线片上肺门的表现是由于血管突出但正常、肺动脉增粗、肺门淋巴结肿大还是肺部肿块所致。
