摘要
早期肺癌以肺腺癌为主,CT上常表现为磨玻璃结节(GGN)影,但其影像表现缺乏特异性,故定性诊断十分困难,而且还可能由于阅片者图像后处理不当、影像征象把握不准、思维过于机械以及随访间隔不合理等因素,易造成GGN的漏、误诊。因此,影像医师需综合运用多种重组方式,结合肺部良恶性GGN的CT表现特点,综合判断并进行合理的随访观察,才能有效减少漏、误诊。
Lung adenocarcinoma is the most common type in early lung cancers. They mainly manifest as ground-glass nodule in CT imageing. Ground-glass nodule has no features on CT imaging, and is very difficult for qualitative diagnosis. Moreover, due to radiologists＇ improper handling, poor judgement on image manifestation, or radiologists＇ mechanical thinking, and improper follow-up interval, sometimes can cause misdiagnosis and missed diagnosis on GGN.Thus radiologists should utilize multiple integrated reconstruction methods, consider the features of benign and malignant GGN on CT, and arrange proper follow-visiting to establish a synthetic judgment, and consequently reduce the occurrence of misdiagnosisdiagnosis.
