Abstract

The purpose of this study is to know the differences of metabolism in abnormal brain disease using a single-voxel proton MR spectroscopy(1H MRS) Together with five normal volunteers and each five patients with brain diseases, pathologically proved, underwent MRI and 1H MRS. The quantitative results of 1H MRS in adrenoleukodystrophy(ALD), hepatic encephalopathy(HE), and infarction gave unique information on the metabolite changes related with the white matter: the concentration of NAA decreased in all diseases; Cho, mI and Lac increased in ALD; Cho decreased in HE; and ${\beta}{\cdot}{\gamma}$-Glx and Lac increased in infarction. It is concluded that 1H MRS is capable of diagnosing brain diseases by monitoring metabolite changes in vivo that subsequently develope into abnormalities. 1H MRS may be a useful clinical tool for in both diagnosis and prognosis of brain diseases.

본 연구의 목적은 단일 복셀 자기공명 분광법을 이용하여 비정상적인 뇌질환을 가진 환자의 뇌대사물질이 어떻게 다른지를 알아보는데 있다. 수소 자기공명분광법의 정량적 분석의 결과 부신백질이영양증, 간선뇌병증, 뇌경색은 백질에 관련된 대사물질에 변화를 보였다. 세질환 모두 NAA가 감소하였고, ALD에서는 Cho, mI 과 Lac가 증가하였고, 간성뇌병변에서는 Cho가 감소, 그리고 뇌경색에서는 ${\beta}{\cdot}{\gamma}$-Glx와 Lac가 증가되었다. 결론적으로 수소 자기공명분광법은 비정상적으로 발전하는 뇌질환의 대사물질의 변화를 관찰하여 병을 진단할 수 있고 이는 임상에서 뇌질환의 진단과 예후를 평가하는데 유용할 것이다.
