Correction to : Pediatric Radiology (2023)

The original published online version stated:

"For primary tumour size, 2-dimensional (D) measurements according to Response Evaluation Criteria In Solid Tumours (RECIST) 1.1 are recommended in the European guideline and used for international studies [17, 24]."

This was an error, and the sentence should read:

"For primary tumour size, 1-dimensional (D) measurements according to Response Evaluation Criteria In Solid Tumours (RECIST) 1.1 are recommended in the European guideline and used for international studies [17, 24]."

The original article has been corrected.
