胸部增强CT可以看到肾上腺

胸部增强CT检查可以看到肾上腺,但肾上腺结节可能无法通过增强CT被明确表征。1

胸部CT对肾上腺的显示能力

  • 胸部CT检查范围通常包括肾上腺,特别是当CT扫描范围延伸到上腹部时1
  • 胸部增强CT可以显示肾上腺结构,但对肾上腺结节的特征描述能力有限1
  • 当胸部CT没有同时进行腹部CT检查时,建议扫描范围应覆盖肾上腺区域1

增强CT与非增强CT对肾上腺的评估差异

  • 非增强胸部CT通常比增强胸部CT更能准确表征肾上腺结节1
  • 增强CT对肾上腺结节的表征能力受限,特别是当肾上腺腺瘤的细胞内脂质含量较低时(约三分之一的肾上腺腺瘤属于这种情况)1
  • 当需要进一步评估肾上腺结节时,可采用以下方法:
    • FDG-PET/CT检查1
    • CT肾上腺灌注(washout)方案1
    • MR化学位移成像(in-phase和out-of-phase成像)1

临床应用中的注意事项

  • 在肺癌分期和随访中,胸部CT常被用于评估肾上腺是否有转移1
  • 美国临床肿瘤学会(ASCO)指南建议,肺癌治疗后的随访应使用包括肾上腺在内的胸部CT1
  • FDG-PET对肾上腺结节的表征敏感性为94%,特异性为82%,优于单纯CT检查1
  • 肾上腺结节在FDG-PET上无摄取被认为是良性肾上腺腺瘤的确定性证据,可避免进一步检查1

肺癌随访中的肾上腺评估

  • 在小细胞肺癌(SCLC)患者中,肝脏和肾上腺是最常见的血行转移部位1
  • 对于接受根治性治疗的I-III期非小细胞肺癌(NSCLC)患者,NCCN和ASCO指南建议进行包括肾上腺在内的诊断性胸部CT检查(最好使用静脉对比剂)1
  • 相比于单独的胸腹盆CT检查,包括肾上腺在内的胸部CT被认为是肺癌复发监测的足够影像学手段1
