我们比较了峰值周向应变（Ecc）值与空间磁化调制（SPAMM）和应变编码（SENC）磁共振（MR）成像在3特斯拉。两种方法的平均Ecc峰值的相关系数有统计学意义。然而，SPAMM的平均峰值Ecc值（-13.5% +/- 3.3%）显著低于SENC（-21.6% +/- 3.4%）（P < 0.0001）。在3 T下，SENC方法显示出比SPAMM方法更高的周向应变。
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.
