Reviewer ’s report  
 
Title: Magnetic Resonance Enterography, Colonoscopy, and Fecal  Calprotect in correlate in 
colonic Crohn ’s Disease  
 
Version: 1 Date: 20 Oct 2019  
 
Reviewer: Andrea Laghi  
 
Reviewer's report:  
 
This prospective single -center trial enrolled 156 patients with colonic Crohn's Disease, aiming at 
finding correlation between MRI, optical colonos copy and fecal calprotectin. Some manuscript 
improvements are suggested below:  
 
* The aim of the study should be stated only in the last paragraph of the introduction; 
therefore, the section should be modified and all the redundancies cut off.  
 
* The study should be clearly labeled as prospective and the time span should be indicated.  
 
* Image acquisition and image analysis should be put into two separate sections. The image 
analysis sections should also be improved.  
 
* Please provide the proper reference for MaRIA score formula and avoid writing down 
results justifying it in this section.  
 
* Was the MaRIA score only calculated on colonic tracts? How many patients have been 
excluded for lack of colonic disease?  
 
* More details regarding the reach of consensus should be given.  
 
* Results section has multiple two -group comparisons not adequately presented in M&;M 
(stats).  
 
* P12L297 -301: self -celebrating sentences should be avoided, and in any case, they don't 
belong  there.  
 
* The quality of the MRI image is low, please find some better images among patients' 
data.
