Overview
Brief Summary
the goal of this clinical trail is to evaluate the efficiency and safety of intracranial aneurysm assistive software in the preoperative assessment. The trail is designed as retrospective, multicenter, controlled clinical trail. Collecting probable cases images retrospectively according to inclusion criteria and exclusion criteria strictly. Controlling bias strictly, to make sure the efficiency and safety of intracranial aneurysm assistive software is evaluated reliably and precisely. In our trail, software-assisstant planning controls against experienced-surgeon-independent planning，which aims to avoid bias effictively and eliminate non-test interferences.

- •the shape of aneurysm is regular without daughter sac or more than 2 lobulations.
- •Inclusion criteria of images:
- •the number of detector rows of Computed Tomography(CT) is more than 16 rows.
- •slice thickness ≤ 0.625mm, whole-brain image is considered.
- •Both plain scan sequences and enhancer sequence are required.
Exclusion Criteria
- •combined with cerebral hemorrhage;
- •combined with cerevascular malformation or cerebral occupying lesion;
- •fusiform aneurysm or dissection aneurysm;
- •significant proximal stenosis of parent artery;
- •intracaverous internal carotid artery aneurysm;

Outcomes
Primary Outcomes
concordance rate
Time Frame: accessment time point : immediately after computational coiling diameter assessment finished.
the optimal coiling diameter used in surgery is considered as "gold standard". The concordance rate is defined as computational suitable coiling diameter in test group differs gold standard less than ±1mm. concordance rate=the number of concordance matched/totle enrolled number\*100%
Secondary Outcomes
- coincidence rate(accessment time point: immediately after computational coiling diameter assessment finished.)
