肿瘤学中的分期适应性治疗依赖于恶性疾病患者的正确肿瘤分期。为了确保PET/CT对胸部和腹部疾病的肿瘤分期进行准确评估，需要对CT和PET进行优化。在这种情况下，不同的恶性疾病需要定制的成像协议。尽管在治疗评估的临床环境中，结合低剂量、非增强CT的PET/CT可能就足够了，但肿瘤分期可能需要更复杂的CT方案。本文综述了胸部和腹部癌症的潜在CT成像协议。CT协议的例子，并讨论了非小细胞肺癌，乳腺癌，结直肠癌，胃肠道间质瘤，介入肝脏治疗。
Stage-adapted treatment in oncology relies on correct tumor staging for patients with malignant diseases. To ensure accurate assessment of the tumor stage in thoracic and abdominal diseases by PET/CT, both CT and PET need to be optimized. In this setting, different malignant diseases require customized imaging protocols. Although in the clinical setting of therapy assessment, PET/CT with integration of low-dose, nonenhanced CT may be sufficient, tumor staging may require a more sophisticated CT protocol. This review focuses on potential CT protocols for imaging cancers of the chest and abdomen. Examples of CT protocols are presented and discussed for non-small cell lung cancer, breast cancer, colorectal cancer, gastrointestinal stromal tumors, and interventional liver therapy.
