Standardization of T1 measurements with MOLLI in differentiation between health and disease – the ConSept study

Table 2 Mean differences (MD) in T1values between septal and SAX ROIs or lateral measurements (LVH – left ventricular hypertrophy, DCM – dilated cardiomyopathy)

MOLLI	Native T1 values (MD ± SD)		Post-contrast T1 values (MD ± SD)		Lambda (MD ± SD)
1.5 T	Septal vs. SAX	Septal vs. Lateral	Septal vs. SAX	Septal vs. Lateral	Septal vs. SAX	Septal vs. Lateral
Normal	16 ± 11	21 ± 43	6 ± 14	11 ± 28	0.002 ± 0.03	0.003 ± 0.06
LVH	20 ± 21	29 ± 49	11 ± 19	13 ± 39	0.01 ± 0.04	0.02 ± 0.09
DCM	28 ± 31	50 ± 64	19 ± 22	25 ± 55	0.02 ± 0.04	0.02 ± 0.11
3 T
Normal	21 ± 22	46 ± 46	10 ± 18	13 ± 20	0.002 ± 0.08	0.02 ± 0.09
LVH	16 ± 41	40 ± 37	17 ± 26	16 ± 37	0.01 ± 0.06	0.01 ± 0.10
DCM	26 ± 49	55 ± 92	24 ± 38	27 ± 43	0.02 ± 0.10	0.02 ± 0.12

For both field strengths and all groups, the MDs were greater for lateral measurements than SAX ROIs (p < 0.05 for all).
