신생아의 두뇌 초음파검사상 뇌실주위 고반향음영에 관한 연구 = The Study on the Periventricular High Echoes of Neonatal Neurosonography

다국어 초록 (Multilingual Abstract)

Neurosonography is an excellent modality for imaging a wide array of intracranial pathology of the infant and the newborn. Periventricular high echos were prominent for the premature infant, but there are some difficulties in differentiate normal periventricular high echo from periventricular leukomalacia.
White matter indices on neurosonography of 152 healthy newborn babies were measured and analized, with their gestational age, method of delivery, birth weight, APGAR score(1 min and 5 min), diagnosis and labaratory data. The gestational age of babies at birth (p=0.0001) and the delivery with Caesarian section (p=0.0263) were related statistcally to high white matter index.
The babies with metabolic disease had higher white matter index than other disease group or normal control group. On the basis of these results, We speculate that in addition to gestational age of infants, delivery method and their disease status may play an additional role in presenting ldgh periventricular echo on neurosonography. It is possible to predict the size of non pathologic periventricular high echo and to give more information for further study plan.
