摘要
孤立性肺结节（SPN）的良恶性诊断非常困难，在诊断不明确而手术切除的结节中，约30％为良性。常规影像学技术虽然可以对大部分SPN做出定性诊断，但对一部分SPN仍然诊断困难，且各具有一定的局限性。PET-CT作为一种新的显像技术，能够综合提供SPN的代谢及形态信息，在SPN的良恶性诊断与鉴别诊断中显示出更高的灵敏度及准确率。近期多种新的显像方法的应用更进一步提高了SPN的诊断准确率。
It is very difficult to differentiate correctly between the benign and malignant solitary pulmonary nodules（SPNs）. About 30% of the resected indefinite SPNs are benign. Conventional imaging techniques can identify most patients with SPN, but cannot afford a few patients with SPN which have equivocate manifestations, and each has some limitations. PET-CT is a new imaging technique that can offer metabolic and anatomical information of SPN, which results in higher diagnostic sensitivity and accuracy of SPN. Recently various new imaging method is further improved the diagnostic accuracy.
