ABSTRACT
PURPOSE:
Artificial intelligence (AI)-based three-dimensional angiography (3D-A) was reported to demonstrate visualization of cerebral vasculature equivalent to that of three-dimensional digital subtraction angiography (3D-DSA). However, the applicability and efficacy of the AI-based 3DA algorithm have not yet been investigated for 3D-DSA micro imaging. In this study, we evaluated the usefulness of the AI-based 3DA in 3D-DSA micro imaging. MATERIALS ANDMETHODS:
The 3D-DSA micro datasets of 20 consecutive patients with cerebral aneurysm (CA) were reconstructed with 3D-DSA and 3DA. Three reviewers compared 3D-DSA and 3DA in terms of qualitative parameters (degrees of visualization of CA and the anterior choroidal artery [AChA]) and quantitative parameters (aneurysm diameter, neck diameter, parent vessel diameter, and visible length of AChA).RESULTS:
Qualitative evaluation of diagnostic potential revealed that visualization of CA and the proximal to middle parts of the AChA with 3DA was equal to that with conventional 3D-DSA; in contrast, visualization of the distal part of the AChA was lower with 3DA than with 3D-DSA. Further, regarding quantitative evaluation, the aneurysm diameter, neck diameter, and parent vessel diameter were comparable between 3DA and 3D-DSA; in contrast, the visible length of the AChA was lower with 3DA than with 3D-DSA.CONCLUSIONS:
The AI-based 3DA technique is feasible and evaluable visualization of cerebral vasculature with respect to quantitative and qualitative parameters in 3D-DSA micro imaging. However, the 3DA technique offers lower visualization of such as the distal portion of the AChA than 3D-DSA.Palavras-chave
