We compared peak circumferential strain (Ecc) values with spatial modulation of magnetization (SPAMM) and strain-encoded (SENC) magnetic resonance (MR) imaging at 3 tesla. Correlation coefficients of the averaged peak Ecc values of the 2 methods were statistically significant. However, the average peak Ecc value was significantly lower with SPAMM (-13.5%±3.3%) than with SENC (-21.6%±3.4%) (P<0.0001). The SENC method showed higher circumferential strain than the SPAMM method at 3T.
