International Survey Evaluating Inter-Observer Variability of Late Gadolinium Enhancement (LGE) Interpretation in Non-Ischemic Cardiomyopathy:

A MINICOR Consortium Initiative

Thank you for your interest in participating in this study.  This study is open to ALL levels of CMR readers and technologists.    

 

You are asked to visually interpret the presence and pattern of LGE in 15 cases performed in patients with Non-Ischemic Cardiomyopathy (NICM). 

 

The aim of this study is to describe the inter-observer variability of LGE interpretation for this patient population.  The results of this survey will be published online in a peer-reviewed journal and, following publication, will made available to all participating readers through direct web access to the data.

 

The survey takes on average 15-20 minutes to complete.  All responses should be based on your own subjective interpretation of the images (as shown).  Non-LGE images have purposely not been provided.

Prior to beginning please click HERE.  This will open a separate browser window (keep open for reference) that provides a guide for naming.  This is to remove subjective bias for naming conventions.

 

Please select ALL patterns that you feel are present.  Identify the MOST likely cause for each patient. 

You may select more than one cause only if you feel the patient has multiple disease states.

 

Thank you again for your support of this important initiative!
