Why the study?

To establish normal myocardial stiffness values in healthy adults using cardiac MR elastography and assess the impact of slice location and demographic factors.

Population

125 healthy volunteers

Comparison

Myocardial stiffness across basal, mid, and apical short-axis views and demographic factors

Design

Cross-sectional study

Key result

Cardiac MR elastography in 125 healthy adults established a global myocardial stiffness of 8.1 ± 1.1 kPa and a significant apical-to-basal gradient (apex 8.7, mid 8.3, base 7.4 kPa; P<0.05).

Overview

Age and slice location must inform cardiac MRE reference ranges; extends normative data for future diagnostic studies.

Key Points

  • This research aims to establish normal myocardial stiffness values in healthy adults and understand how slice location and demographic factors affect these values.
  • 125 healthy volunteers underwent cardiac MR elastography at a 140-Hz vibration frequency.
  • Stiffness was measured at basal, mid, and apical slice locations during early systole.
  • Multiple statistical analyses, including ANOVA and regression, were conducted to assess the data.
  • Global myocardial stiffness was recorded at 8.1 ± 1.1 kPa with an apical-to-basal gradient observed (highest at apex).
  • Age was identified as a significant independent predictor of stiffness, confirmed through multivariable regression.
  • Reproducibility of the MR elastography measurements was excellent, with ICCs ≥0.97.

Cardiac MR elastography demonstrates that normal myocardial stiffness in healthy adults follows an apical-to-basal gradient and increases independently with age, providing location-specific baseline values for clinical interpretation.

Cite This Study

Cheng et al. (2026) conducted a cross-sectional in Healthy adults (n=125). Cardiac MR elastography (MRE) was evaluated on Normal myocardial stiffness values and the impact of slice location and demographic factors. Cardiac MR elastography in 125 healthy adults established a global myocardial stiffness of 8.1 ± 1.1 kPa and a significant apical-to-basal gradient (apex 8.7, mid 8.3, base 7.4 kPa; P<0.05).
