The Editors are issuing an Editorial Expression of Concern for this Article because a concern has been raised that the imaging data presented originate from the patient database of a different institution from that described in the article. The authors have provided their raw data; however, the Editors have not been able to verify the provenance of these data with the authors' institution. The Editors therefore advise readers to interpret the data presented with caution. Xue-Jing Zhang, Wei-Li Hao, Dong-Hai Zhang and Bu-Lang Gao disagree with this statement.
