Reviewer comments  
 
o This is an interesting art icle, and this work will give clinical insight on h ow to use MRI 
techniques for diagnosis hepatic pathologies over liver biopsy techniques  
 
 
 
Topic  
 
o Multiparametric functional MR imaging for evaluation of hepatic warm ischemia -reperfusion 
injury in a rabbit model  
 
 
o The authors should consider changing to "M ultiparametric functional magnetic resonance 
imaging for evaluation of hepatic warm ischemia -reperfusion injury in a rabbit model"  
 
 
 
Abstract page 2  
 
The abstract is ok. But, there is minor grammatical mistake  
 
Page 2 line 24 -26 
 
o The authors compared MR parameters between two groups. Where are the two groups in the 
abstract? The two groups should be mentioned in the material and methods of the abstract for 
clarity.  
 
 
Line 30 -31 
 
o The authors should consider writing PF, MD and MD in  full 
Line 42 -45 
 
o The authors give only histopathological summary of WIRI group. What about the second 
group?  
 
 
o I therefore, recommend the histopathological s ummary of the second group. The 
histopathological of both groups should be compared for clarity.  
 
 
 
Introduction  
 
Page 3 line 30 -37 
 
o I do believe that hepatic WIRI resulted to oxidative stress due to reactive oxygen species(ROS) 
production which eventually lead to antioxidants imbalance and inflammatory cells response.  
 
o I suggest, the authors should ex plain in brief, "the role of WIRI in ROS production", since they 
assayed for oxidative stress markers in this study.  
 
 
 
Materials and Methods  
 
Page 6 line 25 -27 
 
o Describedfrom were written together. I believe that is not the correct spelling.  
 
Page 7 line 1  
 
I suggest, the authors should explain;  
 
o How the animals were sacrificed,  
 
o How the venous blood was collected from each animal and  
 
o How the serum blood was collected and/or separated from RBCs before using it for liver 
function parameter  
 
Line 14 -15 
 
o Why did the authors assayed for only superoxide dismutase (SOD)? There are other enzymatic 
(catalase CAT, glutathione peroxidase GPX, glutathione S transferase etc) and non -enzymatic 
antioxidants (reduced glutathione GSH) that they can assay for. These are j ust to make the study 
more detailed.  
Line 20 -30 
 
o I recommend addition of the liver histological scores of the two groups  
 
 
Results  
 
Page 8 line 35 -39 
 
o The authors should state clearly the statistical or significant difference in ALT, AST, LDH, 
MDA, MPO and SOD among the two groups. Are they higher or lower in WIRI group compared 
to control? Not really clear. This session required more statistical diffe rence details of all these 
parameters.  
 
o Generally, the authors should give more statistical details of the two groups  
 
 
 
Discussions  
 
This is ok  
 
Page 9 line 45 -48 
 
* I suggest, the authors should do hepatic histological scores for the two groups to confirm t he 
hepatocyte death, swelling and inflammatory cell infiltration.  
 
 
In general, this is an interesting article, the results and conclusions well conveyed, but this is just 
a pilot study. More research work with larger population of subjects should be carrie d out. The 
article needs slight grammatical corrections.
