Objective To investigate the value of magnetic resonance imaging (MRI) in the clinical diagnosis of neonatal bilirubin encephalopathy. Methods 90 cases of neonatal bilirubin encephalopathy were selected for the study (April 2021 to May 2022). According to the serum bilirubin level of the children, they were divided into three groups: mild (n=30), moderate (n=30) and severe (n=30). The patients were all examined with brain MRI. The T1WI signal intensity and T2WI signal intensity of the left and right globus pallidus were observed during the examination of the three groups, and the two signal ratios were compared. Results MRI scanning showed that there was no significant difference in T1WI signals of the left and right globus pallidus between the three groups (P>0.05). With the progress of the disease, T1WI signals of the left and right globus pallidus of the above children were significantly enhanced, and the signal intensity of the severe group was the largest, while that of the mild group was the weakest, with significant difference (P<0.05), while there was no significant difference in T2WI signals of the left and right globus pallidus between the three groups (P>0.05); Compared with the signal relief rate, the detection rate of high signal on T1WI in the three groups was significantly higher, and the detection rate was positively correlated with the severity of the disease, with significant difference (P<0.05). The signal detection rate of T2WI had no significant difference (P>0.05). Conclusion In the clinical diagnosis of neonatal bilirubin encephalopathy, both left and right globus pallidus T1WI signal guns can be used as an effective detection indicator, which reflects some characteristics such as high resolution and detection reliability, and has great clinical application value.
