Hi Venkateswaran,

I believe the amount of the distortion is the same between EPI and SS-EPI. I also believe EPI suffers more from signal drop due to the susceptibility artifacts compared to SS-EPI simply because EPI miss the top-of-the-echo time points for data acquisition.

	Hello All,
	 
	I couldn't find the answer to the following question by searching the internet, so i thought seeking your help. I would like to know whether single shot spin echo EPI (for DTI studies) will suffer from same susceptibility artifacts (distortions) like single shot EPI. It will be great if someone could tell me the advantages of SS SE-EPI over SS EPI.
	 
	Thanks in advance.
