[Abstract] Objective: To probe the Value of ESWAN-R2* value in diagnosis of neonatal punctate white matter lesions (PWML).Materials and methods: 22 neonates according with the diagnostic standard of PWML were all performed conventional MRI, DTI, ESWAN examination (10 cases of premature, 12 cases of full-term infants), and 22 cases of normal neonates as controls (10 cases of premature, 12 cases of full-term infants). The neonates of case group and control group were divided into premature group and full-term group respectively. Measure the R2* value of the neonatal PWML lesions, the contralateral side of the lesions, and the same location of lesions in normal neonates, and then compared the values with each other.Results: the R2* value of the lesions, the contralateral side of the lesions, and the same location of lesions in normal neonates of the premature group are as follows: 7.458±2.463, 5.708±2.277, 4.024±0.940, the R2* value of full-term group’s are as follows: 8.609±2.461, 6.621±2.072, 5.250±1.526, the R2* value of the neonatal PWML are higher than the contralateral side of the lesions and the normal neonates, and the differences between lesions and the normal neonates are significant (P<0.05).Conclusion: contrast measurement of ESWAN-R2* value has important value in the diagnosis of neonatal PWML.
