摘要: 目的:丘纹静脉作为大脑内静脉的重要属支,主要引流脑深部基底核及髓质深部静脉血。磁敏感加权成像是一种新的脑静脉成像技术,尤其对微小静脉敏感。本文旨在利用3.0T磁共振磁敏感加权成像序列来探索丘纹静脉及其细小属支的解剖形态,为丘纹静脉性脑血管疾病的诊治和微创神经外科手术提供依据。 方法:选取40名健康志愿者行3.0T磁共振系常规序列以及磁敏感加权成像序列头部扫描,利用最小密度投影(mIps)技术对原始图像进行后处理得到横断面、矢状面及冠状面3个断层的图像。通过SWI原始图像以及重建后图像,对丘纹静脉及其属支的解剖形态进行观察分析。我们将丘纹静脉分为Ⅰ型和Ⅱ型,同时将尾状核前静脉分为2种类型(1型、2型)和3种类型(A型、B型、C型)。结果:丘纹静脉的引流区域包括尾状核、内囊、豆状核、外囊、屏状核、最外囊以及额顶叶脑髓质深部,但丘脑除外。丘纹静脉、尾状核前静脉、尾状核横静脉的显示率依次为92.5%、87.5%、63.8%。丘纹静脉Ⅰ型和Ⅱ型的显示率分别为79.7%、20.3%;并且右侧大脑Ⅰ型更多见(P <0.05)。尾状核前静脉分型中以1支型(80.4%)和A型(68.9%)最常见。结论:磁敏感加权成像能清晰显示活体脑深部丘纹静脉及其细小属支的解剖形态。

Abstract: Objective: Thalamostriate vein is an important tributary of the internal cerebral vein which mainly drains the areas of basal ganglia and deep medulla. Susceptibility-weighted imaging is a very practical technique which is sensitive to veins, especially tiny veins. The purpose of this study was to explore the anatomic morphology of thalamostriate vein and its smaller tributaries by using SWI at 3.0Tesla and then provide the basis for the diagnosis and treatment of cerebral venous disease and the minimally invasive neurosurgery. METHODS: We acquired SWI images in 40 volunteers on a 3.0T MR system by using an 8-channel high-resolution brain phased array coil. The SWI images were reformatted by using minimum intensity projections (mIPs) technique in the transverse, sagittal and coronal plane. The anatomic morphology of thalamostriate vein and its tributaries were evaluated on the original images and reconstructed images. We classified thalamostriate vein into 2 types (Type Ⅰ and Type Ⅱ) . The anterior caudate veins were classified into 2 types (Type 1 and Type 2) and 3 Types (Type A, B and C).RESULTS: The thalamostriate vein drains the areas of caudate nucleus, the internal capsule, lentiform nucleus, the external capsule, the claustrum, the extreme capsule and the white matter of the frontoparietal lobes,except thalamus. The frequencies of the thalamostriate vein, anterior caudate veins and transverse caudate veins were 92.5%、87.5%、63.8%, separately. We found Type Ⅰ and Type Ⅱ in 79.7%, 20.3% and TypeⅠon the right side was more common than the left (P <0.05).The most common types of anterior caudate veins were Type 1 (80.4%) and Type A(68.9%). CONCLUSION: SWI could clearly demonstrate the anatomy of the thalamostriate vein and its smaller tributaries.
