Hi,

A bit of layman's question, but we are trying to refine the way we measure MRI scan time (comparing what we see vs. what we calculate from the tags). Can someone please advise:
1. Is DICOM tag 0018,0083 is the correct representation for NEX (Number of Excitations)?
2. If there is a different calculation when the ETL (Echo Train Length) is large (e.g. 80)? We are currently using DICOM tag 0018,0091 for fast echo calculations.

Tnx,
Amit
