Key Points

This research aims to evaluate the effectiveness of three-dimensional rotational angiography (3DRA) compared to traditional methods in detecting periventricular anastomosis in moyamoya disease.
Conducted a comparative analysis between STS-MIP MRA and 3DRA techniques.
Focused on the detection of periventricular anastomosis (PA) related to moyamoya disease.
Utilized non-invasive imaging methods to assess diagnostic accuracy.
3DRA demonstrated superior detection rates of periventricular anastomosis compared to traditional techniques.
Findings suggest 3DRA could enhance surgical planning by providing better vascular visualization.
Identified PA's role in evaluating bleeding risks associated with moyamoya disease.

Implication

Comparative analysis reveals the effectiveness of 3D angiography in detecting periventricular anastomosis, suggesting potential diagnostic advancements.

Abstract

緒言：もやもや病の診断基準では脳血管造影が必須とされ，実際に各症例における血管構築の把握や手術計画の立案などに大きく貢献するが，脳血管3次元回転撮影（3DRA）の有用性については知られていない．また，もやもや病においては periventricular anastomosis（PA）の発達様式が出血例の再出血や無症候例の初発出血のリスク評価に重要で，その非侵襲的検出法の1つとしてsliding-thin-slab maximum-intensity projection magnetic resonance angiography（STS-MIP MRA）が知られている．今回はSTS-MIPと脳血管造影について，PAの検出力を比較検討した．
