Helical CT angiography is a noninvasive volumetric imaging technique. Images can be relatively safely obtained without the need for arterial puncture or catheter manipulation. CT angiography is not associated with significant patient risks other than those associated with the administration of iodinated contrast media. Multi-section CT angiography is a promising noninvasive screening method for the detection of cerebral aneurysms. This will further increase the quality of 2D and 3D CT angiography images.
Furthermore, angiographic interpretation even of the same scale, as with any other diagnostic tests, may be subject to intraobserver and interobserver variability. In addition to the numerous factors listed above, other study design features might influence reported outcomes. For example, it has been shown in the cardiology literature7 that site readings (ie, angiographic readings done by the operators themselves) may be significantly different than readings performed in an independent core laboratory facility.

MR angiography (MRA) and CT angiography (CTA) are routinely used to diagnose cerebral aneurysms. 1–4 In many instances, these same noninvasive data can be used to plan subsequent treatment. After treatment has been completed, the application of these powerful noninvasive imaging techniques becomes much more challenging owing to the interaction of the various therapeutic devices (ie, aneurysm clips, embolic coils, and/or stents) with the proton relaxation signal intensity or photon flux in MR imaging and CT, respectively, in the region of the treated aneurysm.

Angiographic images of each coiled aneurysm, taken immediately after embolization and at 5- to 7-month follow-up, were evaluated by the operator at the treating center and by an independent neuroradiologist at the core laboratory. For the purpose of this study, images were interpreted on a 3-point scale to provide uniformity for analysis; grade 1: complete occlusion, grade 2: neck remnant; and grade 3: sac filling.

Compared with the preoperative CT and/or MRI, any newly-developed infarctions in the striatocapsular area were regarded as perforator injuries even if they were very small and asymptomatic. A perforator injury was found in 14 out of 91 cases (15%).

Objective: Adverse effects of increased use of cerebral digital subtraction angiography (DSA) include radiation-induced skin reactions and increased risk of malignancy. In January 2016, the 'dose parameter' was reset by the manufacturer from . μGy to . μGy.
Problems of correlating ischemic lesions of the brain with the cerebral vessel involved originate in the axial scanning direction. Using a method based on detailed perception of the base of the skull and physiological calculations, it is possible to reconstruct the individual baseline of the scan and to project the outlines of the slices upon the lateral view of the angiogram
