Reviewer ’s report  
 
Title: Magnetic Resonance Enterography, Colonoscopy, and Fecal Calprotectin correlate in 
colonic Crohn ’s Disease  
 
Version: 1 Date: 01 Oct 2019  
 
Reviewer: Antonino Caruso  
 
Reviewer's report:  
 
The Authors performed a study to assess the correlation between FCP, MRE and colonoscopy in 
CD patients.  
 
156 patients with colonic CD were included in the study.  
 
Different studies, in past years, evaluated the correlation between radiological (with con strat 
medium and DWI), biochemical and endoscopic parameters in ileo -colonic CD(see Caruso A. et 
al., IBD 2014; Rimola et al 2009).  
 
 
I suggest these revisions:  
 
- specify (in a table or in materials and methods section) the type of pharmacological therapy o f 
patients  
 
- add a control group
