We hypothesized that with minimal training non-specialists could perform similarly to specialist physicians in the diagnosis of cystic lung disease. Methods: 72 cystic lung disease cases and 25 cystic lung disease mimics were obtained from three sources: 1) a prospective acquired diffuse lung disease registry, 2) a retrospective search of medical records and 3) teaching files. Cases were anonymized, randomized and interpreted by 7 diffuse lung disease specialists and 15 non-specialist radiologists and pulmonologists. Clinical information other than age and sex was not provided. Prior to interpretation, non-specialists viewed a short PDF training document explaining cystic lung disease interpretation. Results: Correct first choice diagnosis of 85%-88% may be achieved by high-performing specialist readers and 71%-80% by non-specialists and lower-performing specialists, with mean accuracies in the diagnosis of LAM (91%, p Conclusion: With specific but limited training, non-specialist physicians can diagnose cystic lung diseases from CT appearance alone with similar accuracy to specialists, correctly identifying approximately 75% of cases.展开更多
骨嗜酸性肉芽肿（eosino-philic granuloma of bone,EGB）是一种原因不明的缓慢进展的可侵犯全身骨骼的溶骨性病,在单发病灶中以颅骨最多见,其中又以额骨居多,其次为顶骨和枕骨。颞骨嗜酸性肉芽肿发病年龄多在1～4岁,男女发病率约为2∶1...骨嗜酸性肉芽肿（eosino-philic granuloma of bone,EGB）是一种原因不明的缓慢进展的可侵犯全身骨骼的溶骨性病,在单发病灶中以颅骨最多见,其中又以额骨居多,其次为顶骨和枕骨。颞骨嗜酸性肉芽肿发病年龄多在1～4岁,男女发病率约为2∶1,病因目前仍不十分明确,颞骨嗜酸性肉芽肿临床上少见,现报道1例。展开更多
