Comments and Suggestions for Authors

Magnetic resonance imaging findings corresponding to vasculitis as defined by [18F] FDG positron emission tomography or ultrasound.

This manuscript discusses an important and hot topic for the rheumatologists. However, some points need to be addressed.

Page	Line	Manuscript	Comment
1	18	tomography (PET/CT) or ultrasound	The authors mean and not or
1	25	MRI showed mural thickening in	The results should be arranged chronologically according to the methods
2	50	Furthermore, studies comparing MRI	It will be better of the authors give short notes about these studies and the nature of the comparison
2	62	PET/CT underwent a prospective thoracic  study MRI in the frame of our local Ethics	This is not a prospective ,this is still a cross sectional ..it is better to be edited as it is confusing
2	64	In addition, we included 4 patients from our local GCA cohort that un-64 derwent all three imaging modalities but were not prospectively included (Basler Riesen-65 zellarteriitis Kohorte [BARK EKNZ, #239/09]).	Un necessary details which may be confusing to the readers

Reviewer 2 Report

Comments and Suggestions for Authors

Thank you for the opportunity to review this manuscript. In this study authors have analyzed the correlation between the findings of different imaging modalities in patients with GCA. This is an interesting study and has several strengths as well as limitations. Firstly, the analysis presented in this manuscript is purely descriptive. Without statistical analysis, only limited inferences can be made from this study. This should be mentioned in the limitation section. There are other limitations including the use of glucocorticoids prior to imaging that can affect the findings of imaging modalities is question, especially MRI. These have been limitations have been highlighted by the authors. The strength of this study is that both the radiologist and the nuclear medicine expert were blinded to the patients. Despite of the limitations of this study, it provides important preliminary evidence that can potentially provide guidance for future larger clinical studies.
