Abstract:
Objective To compare the clinical value of cranial ultrasound and head CT in the diagnosis of neonatal brain diseases.Methods One hundred and six high risk newborns were selected.All the newborns underwent cranial ultrasonography and head CT examination,and the diagnostic effects of the two methods were compared.Results Of the 106 newborns,there were 83 cases of positive ultrasonic examination and 23 cases of negative,including 14 cases of misdiagnosis and missed diagnosis that diagnosed by cranial ultrasound.There were 66 cases of positive head CT examination and 40 cases of negative,including 37 cases of misdiagnosis and missed diagnosis that diagnosed by CT.The diagnostic sensitivity of the cranial ultrasound was 87.91%,the specificity was 80.00%,the positive predictive value was 96.39%,the negative predictive value was 52.17%,and the diagnostic accuracy was 86.79%.The sensitivity of head CT was 65.93%,the specificity was 60.00%,the positive predictive value was 90.91%,the negative predictive value was 22.50%,and the diagnostic accuracy was 65.09%.The diagnostic sensitivity and accuracy of cranial ultrasound were higher than those of head CT,and the differences were statistically significant(x2=12.381,P =0.00;x2 =13.658,P =0.00).The specificity,positive predictive value and negative predictive value between the two methods had no statistically significant differences (x2 =1.429,P =0.23;x2 =1.943,P =0.16;x2 =2.759,P =0.10).In addition,10 cases of subarachnoid and subdural hemorrhage,13 cases of intracerebral hemorrhage,25 cases of ventricular dilatation,17 cases of hypoxic-ischemic encephalopathy,and 18 cases of hydrocephalus were detected by cranial ultrasound.Compared with the actual diagnosis,the difference was not statistically significant(x2 =1.134,P =0.89).Head CT showed 18 cases of subarachnoid and subdural hemorrhage,10 cases of intracerebral hemorrhage,16 cases of ventricular dilatation,8 cases of hypoxic-ischemic encephalopathy,and 14 cases of hydrocephalus.Compared with the actual diagnostic results and the results of cranial ultrasonic diagnosis,the differences were statistically significant (x2 =15.091,P =0.00;x2 =15.879,P =0.00).Conclusion The diagnostic sensitivity and accuracy of cranial ultrasound are higher than CT.The diagnosis of cranial ultrasound is consistent with the actual diagnosis.Cranial ultrasound can be widely promoted in clinical practice.
