Abstract
Purpose: To scan a volunteer population using 3.0T magnetic resonance imaging (MRI). MRI of the left ventricular (LV) structure and function in healthy volunteers has been reported extensively at 1.5T.
Materials and Methods: A population of 1528 volunteers was scanned. A standardized approach was taken to acquire steady-state free precession (SSFP) LV data in the short-axis plane, and images were quantified using commercial software. Six observers undertook the segmentation analysis.
Results: Mean values (±standard deviation, SD) were: ejection fraction (EF) = 69 ± 6%, end diastolic volume index (EDVI) = 71 ± 13 ml/m2, end systolic volume index (ESVI) = 22 ± 7 ml/m2, stroke volume index (SVI) = 49 ± 8 ml/m2, and LV mass index (LVMI) = 55 ± 12 g/m2. The mean EF was slightly larger for females (69%) than for males (68%), but all other variables were smaller for females (EDVI 68v77 ml/m2, ESVI 21v25 ml/m2, SVI 46v52 ml/m2, LVMI 49v64 g/m2, all P <0.05). The mean LV volume data mostly decreased with each age decade (EDVI males: -2.9 ± 1.3 ml/m2, females: -3.1 ± 0.8 ml/m2; ESVI males: -1.3 ± 0.7 ml/m2, females: -1.7 ± 0.5 ml/m2; SVI males: -1.7 ± 0.9 ml/m2, females: -1.4 ± 0.6 ml/m2; LVMI males: -1.6 ± 1.1 g/m2, females: -0.2 ± 0.6 g/m2) but the mean EF was virtually stable in males (0.6 ± 0.6%) and rose slightly in females (1.2 ± 0.5%) with age.
Conclusion: LV reference ranges are provided in this population-based MR study at 3.0T. The variables are similar to those described at 1.5T, including variations with age and gender. These data may help to support future population-based MR research studies that involve the use of 3.0T MRI scanners.
