Abstract

Purpose: As the lenticulostriate arteries (LSAs) perfuse neurologically important areas, it is necessary to accurately assess the origin and number of the LSAs before surgery. Although three-dimensional time-of-flight MR angiography (3D-TOF MRA) is a non-invasive procedure, it requires high-resolution (HR) images to depict the LSAs with a small diameter. Therefore, we performed 3D-TOF MRA with the maximum HR (HR-MRA) using a 3 T scanner to examine whether a good depiction of the LSAs, equivalent to that of digital subtraction angiography (DSA), could be obtained.

Methods: Our study group comprised 16 consecutive patients who underwent HR-MRA and 3D-DSA. In both studies, we evaluated the localization of the origin from M1, M2, or A1 segments, their number of stems, and depiction.

Results: There was no significant difference in the visualization of the LSAs between HR-MRA and 3D-DSA (P values; M1, M2, and A1 = 0.39, 0.69, and 0.69, respectively), and both the number of stems and the localization of the origin of the LSAs corresponded between the two examinations.

Conclusion: HR-MRA at 3 T can depict the LSA well. It reveals the number of the LSA stems and the LSA origin comparatively with DSA.

在3T高分辨率3D-TOF MRA上观察豆纹动脉的解剖信息：与3D-DSA的比较。

目的：由于豆纹动脉（LSA）灌注神经系统的重要区域，有必要在手术前准确评估LSA的来源和数量。尽管三维飞行时间磁共振血管成像（3D-TOF MRA）是一种非侵入性手术，但它需要高分辨率（HR）图像来描绘小直径的LSA。因此，我们使用3T扫描仪进行了具有最大HR的3D-TOF MRA（HR-MRA），以检查是否可以获得与数字减影血管造影术（DSA）相当的LSA的良好描述。方法：我们的研究组包括16名连续接受HR-MRA和3D-DSA的患者。在这两项研究中，我们评估了M1、M2或A1片段的起源定位、茎的数量和描述。结果：HR-MRA和3D-DSA在LSA的可视化方面没有显著差异（P值；M1、M2和A1 = 分别为0.39、0.69和0.69），并且LSA的茎数和起源的定位在两次检查之间都对应。结论：HR-MRA在3T时能很好地描述LSA。与DSA相比，它揭示了LSA词干的数量和LSA的起源。

期刊介绍： Anatomy is a morphological science which cannot fail to interest the clinician. The practical application of anatomical research to clinical problems necessitates special adaptation and selectivity in choosing from numerous international works. Although there is a tendency to believe that meaningful advances in anatomy are unlikely, constant revision is necessary. Surgical and Radiologic Anatomy, the first international journal of Clinical anatomy has been created in this spirit. Its goal is to serve clinicians, regardless of speciality-physicians, surgeons, radiologists or other specialists-as an indispensable aid with which they can improve their knowledge of anatomy. Each issue includes: Original papers, review articles, articles on the anatomical bases of medical, surgical and radiological techniques, articles of normal radiologic anatomy, brief reviews of anatomical publications of clinical interest. Particular attention is given to high quality illustrations, which are indispensable for a better understanding of anatomical problems. Surgical and Radiologic Anatomy is a journal written by anatomists for clinicians with a special interest in anatomy.
