International T1 Multicentre Outcome CMR Study

Overview 

Aims
The  international T1 mapping multicentre consortium was established in 2012 with aim to accumulate a large data collective in a number of disease contexts using a unified T1 mapping sequence based on modified Look-Locker Imaging (MOLLI) and postprocessing approach (ConSept). The consortium originally consisted of CMR centres using 1.5 and 3T Philips scanners that adopted standardised T1-mapping MOLLI sequence, which was developed and validated by Drs Nagel and Puntmann. Since 2016, this sequence is also available on Siemens 1.5T and 3.0T scanners, thus, providing the first T1 mapping sequence, which is transferable cross-vendor in terms of normal values and clinical experience. The respective sequences, sequence parameters, normal values and clinical evidence have been published in a number of publications (below) and are freely downloadable from this website.  
Biomarker qualification pathway of T1 mapping in characterisation of diffuse myocardial disease: 
  1. To undertake validation and standardisation of T1 mapping acquisition and postprocessing
  2. To establish of interscanner/vendor transferability
  3. To establish normal ranges/ clinical relevant ranges
  4. To determine the context of use by proof of concept studies in model diseases 
  5. To establish predictive associations for T1 mapping measures with outcome.

T1 and T2 mapping sequences

SUBJECT TO  PATENT PROTECTION AND SHARING AGREEMENT
IMPORTANT INFORMATION regarding MOLLI sequences:  ​there are several variants of MOLLI sequences available.  These sequences are not identical, as they rely on very different imaging parameters. Consequently, they have very different normal values and have different sensitivity/specificity for disease detection. The MOLLI sequences are not interchangeable. Please note that we do not recommend changing any parameters in our sequence as it would invalidate any relation with the published evidence, including the normal values and clinical experience. This can be only transferable using this sequence unchanged.

Interested to Collaborate?

We welcome anyone with interest to help acquire new knowledge and with commitment to consistently deliver good quality data. Participating in this study is exciting: we provide support with learning about the methods and how to do the scanning/postprocessing. You will be taking part in the many clinical discoveries and publications. Participation is subject to standard research and authorship agreements and the available site set-up, including provision of local ethic committee approvals, compliance with principles of good clinical practice in clinical research. All new sites  will undergo initiation with travelling phantom and healthy volunteer studies. No previous experience in T1 mapping is necessary.
