ABSTRACT
Objective To evaluate the optimal selection of 8-channel NV Array-related coil(NV Array-A)in neonatal head MRI exam-ination.Methods A total of 84 newborn infants were divided into two groups with 42 cases in each group, and they were examined by 8-channel NV Head-A coil and NV Array-A coil respectively.The same scan parameters were used to obtain transversal T 1-weighted, T2-weighted,T2 Flair,diffusion-weighted imaging and sagittal T1 weighted imaging and other images.Compared and analyzed the image quality of the two groups,including image signal to noise ratio,uniform image signal and coil artifacts.Results In the 8-channel NV Head-A coil group,the image signal to noise ratio was 83.3%,the rate of uniform image signal was 33.3%,and the rate of clear image without coil artifacts was 81.0%.The corresponding data in the 8-channel NV Array-A coil group were 97.6%,4.8%,and 100%respectively.Examina-tion with NV Array-A coil could improve the image signal to noise ratio and reduce the rate of uniform image signal and coil artifacts.And there were statistically significant difference in the rate of uniform image signal and coil artifacts between the two groups(P<0.05).Conclu-sion The effect of NV Array-A coil scanning image in neonatal brain MRI is superior to that of NV Head-A coil,and the uniform image sig-nal and coil artifacts can be obviously reduced.NV Array-A coil is more suitable for neonatal brain MRI examination.
