Table 2 Difference between T1IR and T1SE in CNR based on type of lesion

From: T1 inversion recovery pulse sequence: could it replace T1 spin echo sequence in neuroimaging by improving tissue contrast?

  MR sequences Pre-contrast CNR Post-contrast CNR
Extra-axial lesion T1IR − 13.90 (2.86)* 13.17 (3.01)
T1SE − 6.82 (1.23) 18.48 (3.48)
p value 0.02 0.06
Intra-axial lesion T1IR − 12.87 (2.40)* 16.46 (4.07)
T1SE − 8.11 (0.93) 17.08 (2.65)
