3T MRI investigation of cardiac left ventricular structure and function in a UK population: The tayside screening for the prevention of cardiac events (TASCFORCE) study

摘要: 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 Methods: A 1528 was scanned. standardized approach taken to acquire steady-state free precession (SSFP) LV data short-axis plane, images were quantified commercial software. Six observers undertook segmentation analysis. Results: Mean values (±standard deviation, SD) were: ejection fraction (EF) = 69 ± 6%, end diastolic volume index (EDVI) 71 13 ml/m, systolic (ESVI) 22 7 stroke (SVI) 49 8 mass (LVMI) 55 12 g/m. The mean EF slightly larger for females (69%) than males (68%), but all other variables smaller (EDVI 68v77 ESVI 21v25 SVI 46v52 LVMI 49v64 g/m, P < 0.05). mostly decreased with each age decade males: –2.9 1.3 females: –3.1 0.8 ml/m; –1.3 0.7 –1.7 0.5 0.9 –1.4 0.6 –1.6 1.1 –0.2 g/m) virtually stable (0.6 0.6%) rose (1.2 0.5%) age. Conclusion: reference ranges are provided this population-based MR study 3.0T. similar those described 1.5T, including variations gender. These may help support future research studies that involve use scanners. J. Magn. Reson. Imaging 2016;44:1186–1196.
