The purpose of this study is to investigate the application value of a 3D high-resolution fat-saturated (FS) T1 SPACE sequence for the diagnosis of intracranial vertebrobasilar dissecting aneurysm (VBDA). With sub-millimetric and nearly isotropic acquisition, the 3D T1-SPACE sequence demonstrated good sensitivity and specificity for the detection of the imaging features associated with VBDAs using a large coverage area and a thin slice thickness.
