Correction to: European Radiology https://doi.org/10.1007/s00330-020-07242-5 The original version of this article, published on 11 September 2020, unfortunately contained mistakes. The following corrections have therefore been made in the original: In the last paragraph of section “Variables,” the third sentence should read: “Scores ranging from 4 to 5 for WFNS and 3–5 HH and 3–4 for mRS and SEBES were considered high for each respective scoring method.” In addition, the definition for WFNS was given incorrectly in Tables 1, 3, and 4 and the values of High WFNS were partly incorrect in Table 3. The corrected tables are given below. The original article has been corrected.
