Correction to: BMC Medical Imaging (2021) 21:176 https://doi.org/10.1186/s12880-021-00706-0

Following the publication of the original article [1], the authors requested to amend the article title from “Histogram analysis of diffusion-weighted magnetic resonance imaging as a biomarker to predict LNM in T3 stage rectal carcinoma” to “Histogram analysis based on multi-parameter MR imaging as a biomarker to predict lymph node metastasis in T3 stage rectal cancer”.

The correct title is included in this Correction and has already been updated in the original article.
