Assessment of Myocardial Stiffness in Healthy Adults by Magnetic Resonance Elastography: Effects of Slice Location and Demographic Factors
Abstract
To establish normal myocardial stiffness values in healthy adults using cardiac MR elastography (MRE) and assess the impact of slice location and demographic factors. 125 healthy volunteers underwent cardiac MRE using a 140-Hz vibration frequency, with data acquired during early systole (approximately 100 ms after the R-wave). Stiffness was measured in basal, mid, and apical short-axis views. Statistics included repeated-measures ANOVA (slice locations), t-tests (sex), Spearman correlation (age), and multivariable linear regression (controlling for age, sex, body mass index, and body surface area). Global myocardial stiffness was 8.1 ± 1.1 kPa. A significant apical-to-basal gradient existed (apex: 8.7 ± 1.1, mid: 8.3 ± 1.2, base: 7.4 ± 1.3 kPa; all P
