두개내에서 발생하는 혈관 질환의 진단에 있어서 자기공명 혈관 조영술의 역활 및 가치 : 고식적인 혈관 조영술과의 비교 분석 Comparative Analysis with Conventional Angiography = The Role and Value of the MR Angiography of vascular Lesions in the Brain

다국어 초록 (Multilingual Abstract)

The clinical value of three-dimensional time-of-flight magnetic resonance angiography(MRA)was retrospectively evaluated in 23 patients with arteriovenous malformations(AVM) in 8 andaneurysms in 15 cases. MR angiogram were compared with conventional angiogram(CA) in allcases. The topography of the AVM nidus and feeding artery were equally well appreciated onthe MRA as on the conventional angiogram except one of nidus that was obscured by methemoglobin stated hematoma. Howevere, in four of 8 AVM, the draining veins were incompletelyshown on MRA because of slow flow effect or out of field of view. In cases of aneuryms, allwere equally depicted on MRA as on the conventional angiogram. But, the neck of aneurysmwas more better shown on MRA than CA. MR angiography reliably depict intracranial vascularlesions, especially aneurysm and arteriovenous malformation.
