Table 1 SNR, contrast-to-noise ratio, and relative SI values in different regions of interest in myocardium at TI0.

From: Assessment of myocardial infarction in mice by Late Gadolinium Enhancement MR imaging using an inversion recovery pulse sequence at 9.4T

a) SNR:

 

   Normal myocardium

17.2 ± 2.4*

   Infarcted myocardium

82.1 ± 10.8

   Blood

48.7 ± 16.6

b) Contrast-to-noise ratio:

 

   Infarcted compared with normal myocardium

76.6 ± 19.8

   Infarcted compared with blood

25.7 ± 14.7

   Blood compared with normal myocardium

40.6 ± 21.2

c) Relative SI (%)

 

   Infarcted compared with normal myocardium

344.9 ± 60.4

   Blood compared with normal myocardium

144.6 ± 77.3

  1. Mean (± SEM) (*p < 0.05 viable vs infarcted myocardium).
