The primary imaging modality for the detection of pulmonary metastases is computed tomography (CT). Ideally, a helical CT scan with 3- to 5-mm reconstruction thickness or a volumetric thin section scanning should be performed within 4 weeks of pulmonary metastasectomy. A period of observation to see whether further metastases develop does not seem to allow better patient selection. If positron emission tomography is available, it may identify the extrathoracic metastatic sites in 10 to 15% of patients. Despite helical CT scan, palpation identifies the metastases not detected by imaging in 20 to 25% of patients and remains the standard. No data define the optimal interval for follow-up surveillance imaging.
检测肺转移的主要成像方式是计算机断层扫描（CT）。理想情况下，应在肺转移瘤切除术后 4 周内进行螺旋 CT 扫描，重建厚度为 3-5mm 或容积薄层扫描。观察一段时间以确定是否有进一步的转移似乎并不能更好地选择患者。如果有正电子发射断层扫描（PET），则可能在 10%至 15%的患者中识别出胸外转移部位。尽管有螺旋 CT 扫描，但触诊仍能在 20%至 25%的患者中识别出影像学未检测到的转移灶，触诊仍然是标准方法。目前尚无数据定义最佳的随访监测成像间隔。
