[The diagnostic value of computed tomography and ultrasonography for detecting hypoxic-ischemic encephalopathy]
Objective:
To investigate diagnostic value of computed tomography (CT) and ultrasonography for detecting hypoxic-ischemic encephalopathy (HIE) and to evaluate their clinical implications.
Methods:
94 neonates were examined with CT and ultrasonography, respectively, for detecting HIE and the results were compared to clinical investigation.
Results:
Significant difference (P < 0.01) was found for diagnosis of mild and moderate HIE by CT and ultrasonography. Compared with clinical diagnosis, the agreement rates of ultrasonography and CT were 83% and 39% (P < 0.01) for mild HIE, and 100% and 43% (P < 0.01) for moderate HIE respectively. There was no difference for detecting severe HIE among clinical diagnosis, CT and ultrasonography. Additionally, 9 cases with intracranial hemorrhage were detected by CT in which only 3 cases were found by ultrasonography.
Conclusions:
Compared with clinical finding for diagnosis of mild and moderate HIE, the agreement rate of ultrasonography is higher than that of CT. However, CT is more sensitive to detect intracranial hemorrhage than ultrasonography.
