Dual band Spectral Spatial PRESS (SS-PRESS) was compared with TE averaged PRESS (J-PRESS) in 72 breast lesions and SS-PRESS demonstrates advantages in prescan successfulness and better SNR than J-PRESS. While the sensitivity and specificity of SS-PRESS was also tested in a 153-breast lesion group. If limited the lesion type to 1.5cm and upper, the sensitivity of SS-PRESS reached 76.7% and specificity is 85.4%. SS-PRESS scan can also be automatically reconstructed by host scanner and exhibit clinical convenience.
