After publication of this article [1], the authors reported that affiliation 1 was incorrectly given as ‘Department of Radiology, Wuhan Union Hospital, Tongji Medical College, Huazhong University of Science and Technology, Jiefang Avenue #1277, Wuhan 430022, China’ but should have been 'Department of Radiology, Union Hospital, Tongji Medical College, Huazhong University of Science and Technology, Jiefang Avenue #1277, Wuhan 430022, China’.

The original article [1] has been corrected.
