目的：研究病变的多种影像和多种方法的诊断。方法：通过生化指数的异常，用铟标记的单光子发射作层成像，CT和MR几种方法得到了一个1cm结节的肺部周围型类癌的诊断。结果：1cm肺结节的CT和MR的影像表现得不典型，但结合多种检查方法，如单光子发射作层成像，得到了明显诊断。结论：在影像诊断中要结合病变的多种影像和多种检查方法来发现病变，得到明确诊断。 Objective: To study the multiple images of lesions and the diagnosis of multiple methods. Methods: Through the abnormal biochemical index, indium-labeled single-photon emission imaging was used for imaging. CT and MR methods were used to diagnose a 1cm nodule perianal lung carcinoid. Results: CT and MR images of 1cm pulmonary nodule appeared to be atypical, but combined with a variety of examination methods, such as single photon emission imaging, was clearly diagnosed. Conclusion: In imaging diagnosis, we must combine multiple images of lesions and various examination methods to find the lesions and get a clear diagnosis.
