Type of MRI lesion?
Correct |
88 (83.1) | 103 (97.1) | 70 (66.1) | 77 (72.6) | 2 (1.8)* | 106 (100) | 17 (16.1) | 53 (50) | 79 (74.5) | 62 (58.4) | 97 (91.5) |
We requested the neurologists to identify the images (MRI) and then ascertain if the lesion is characteristic of NMOSD. A list with various options was given for the participants to select the accurate type of lesion. We displayed numbers and percentages of correct responses for each image. The images can be observed in Figure 1 .
*A total of 92 responders chose infratentorial lesions (middle cerebellar peduncles).
Correct answers are shown in bold.
