Positron Emission Tomography in Coronary Heart Disease
Round 1
Reviewer 1 Report
This short review is very interesting.
I have the 3 following comments:
1- May I suggest to show the assessment of myocardial perfusion with 13N-ammonia-PET and Rubidium-82 (Rb) in one patient and/or one animal in order to compare these two imaging modalities.
2- The presentation of the References section is heterogeneous. Please correct.

3- Please insert a space after the term "with" in the following sentence "Imaging myocardial perfusion withRubidium-82 (Rb)"

Reviewer 2 Report
this review addresses the issue of PET applications in cardiovascular imaging. It represents a general overview concerning technical aspects and potential clinical applications.
This approach lacks in details because doesn’t produces enough useful information neither on instrumentation neither on clinical issue.
In particular the distinction of all paragraphs in two sections (general and clinical impact) doesn't make any sense. The sections have to be unified.
Recent articles and one review have been analysed the relationship between immune-regulation and glucose metabolism. These papers have to be considered for the revision of FDG section.
FIG1. the image should recomposed to emphasise the relation with calcium content of the plaque detected by CT. Please report the time from NAF injection
THE PARAGRAPH SHOULD PROVIDE A DEFINITIVE CLINICAL INDICATION WHEN POSSIBLE.
PLEASE INSERT A LARGER DISCUSSION CONCERNING THE Rb ADVANTAGES OVER TRADITIONAL MPI.
