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.

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.
