Table 3 Summary statistics quantifying ex vivo left ventricle wall thickness and left ventricle chamber diameter with comparison to predicted in vivo values from body mass

From: Comparison of diffusion tensor imaging by cardiovascular magnetic resonance and gadolinium enhanced 3D image intensity approaches to investigation of structural anisotropy in explanted rat hearts

Ventricular wall thickness/chamber-diameter measured Measured thickness in ex vivo FLASH Predicted in vivo diastolic thickness Predicted diastolic thickness as percentage of measured Predicted in vivo systolic thickness Predicted systolic thickness as percentage of measured
Interventricular septum 3.0 ± 0.1 1.0 ± 0.0 33.3% 1.7 ± 0.0 56.7%
Left ventricular posterior wall 3.5 ± 0.3 1.3 ± 0.0 37.1% 1.8 ± 0.1 51.4%
Left ventricular diameter 3.7 ± 0.3 6.2 ± 0.1 168.6% 3.5 ± 0.0 94.6%
  1. Data in this table allows comparison of the state of the fixed ex vivo hearts with in vivo contraction states (diastolic/systolic). The in vivo ventricular wall thicknesses are predicted from body-mass using the published equations (fitted to echocardiographic data) [37]. To assist comparison the predicted in vivo diastolic and systolic thicknesses are expressed as a percentage of the measured ex vivo FLASH thickness. The values listed for the thicknesses are mean ± SD. FLASH: fast low angle shot.
