Sex- and age- specific normal values of left ventricular functional and myocardial mass parameters using threshold-based trabeculae quantification.

ABSTRACT:

Background

The threshold-based (TB) trabeculated and papillary muscle mass (TPM) quantification method for cardiac MRI (CMR) calculates different values than conventional contouring techniques. We aimed to identify the sex- and age-related normal reference ranges for left ventricular (LV) myocardial mass values, volumetric and functional parameters and the correspondence of these parameters using the TB method.

Methods

Healthy European adults (n = 200, age: 39.4 ± 12 years, males: 100) were examined with CMR and evaluated with a TB postprocessing method. They were stratified by sex and age (Group A: 18-29, Group B: 30-39, Group C: 40-49, Group D: >50 years). The calculated parameters were indexed to body surface area (i).

Results

The normal reference ranges for the st
