[Visualization of Cerebrospinal Micro-Angioarchitecture].

Researchers have been trying to visualize fine angioarchitecture in cerebrospinal vascular lesions and the positional relationship between vascular lesions and surrounding structures. The aim of this article was to introduce the usefulness of imaging in visualizing the microvascular anatomy in cerebrospinal vascular lesions, such as aneurysm, arterial dissection, arteriovenous malformation, dural arteriovenous fistula(AVF), spinal dural and epidural AVF, and craniocervical junction AVF. For the imaging modality, we used high-resolution magnetic resonance imaging, three-dimensional rotational angiography(3D-RA), slab maximum intensity projection image from 3D-RA, cone-beam computed tomography, and fusion imaging. If fully exploited, imaging can contribute to clinical analysis and surgical treatment and be an essential tool for achieving maximum therapeutic effect without complications.
