The primary role of imaging procedures in the patient with lung cancer should be focused on staging and follow-up challenges. The role of imaging procedures in the detection of the patient at risk for primary lung cancer remains limited and cannot be recommended at present. There is no significant difference between the yield of CT and MR in this patient group, with the possible exception of a more specific role for MR when questions are raised concerning hilar lymph node involvement and mediastinal compartmental invasion. The main role of cross-sectional imaging techniques should be in the avoidance of unnecessary surgical procedures, identifying the unresectable patient prior to exploratory thoracotomy. It should be emphasized that all radiographic abnormalities are non-specific and must be histologically verified before presuming that an abnormal lymph node or large adrenal gland contains metastatic lung cancer.
成像检查在肺癌患者中的主要作用应集中于分期和后续挑战。成像检查在检测原发性肺癌高危患者方面的作用仍然有限，目前不推荐使用。在该患者群体中，CT和MR的检出率没有显著差异，可能的例外是，当对肺门淋巴结受累和纵隔间隙侵犯存在疑问时，MR可能具有更特殊的作用。横断面成像技术的主要作用应是避免不必要的外科手术，在进行 exploratory thoracotomy（此处可能有误，推测为exploratory thoracotomy即开胸探查术）之前识别出不可切除的患者。需要强调的是，所有影像学异常都是非特异性的，在假定异常淋巴结或大肾上腺含有转移性肺癌之前，必须进行组织学验证。
