Risk Factors for Asymptomatic Intracranial Small Aneurysm Rupture Determined by Electrocardiographic-Gated 4D Computed Tomographic (CT) Angiography

BACKGROUND To study the risk predictors of intracranial asymptomatic small aneurysm rupture by electrocardiographic (ECG)-gated 4D-CT angiography (4D-CTA). MATERIAL AND METHODS A total of 168 patients with intracranial aneurysms 1.65 were independent predictors for the rupture of asymptomatic small intracranial aneurysms <7 mm in diameter.
