BACKGROUND AND PURPOSE: In some patients with nonperimesencephalic nontraumatic
subarachnoid hemorrhage (aneurysmal SAH), no aneurysm can be found on digital …

BACKGROUND: Three dimensional rotational angiography (3DRA) is a powerful method for
depicting intracranial vascular lesions because of its 3D imaging capability. The purpose of …

Introduction CT angiography (CTA) is increasingly used as primary diagnostic tool to replace
digital subtraction angiography (DSA) in patients with subarachnoid hemorrhage (SAH) …

BACKGROUND AND PURPOSE: Rotational angiography (RA) and digital subtraction
angiography (DSA) together may depict more intracranial aneurysms than DSA alone. We …

Introduction Ruptured intracranial aneurysms are responsible for over 90% of cases of
spontaneous subarachnoid hemorrhage (SAH). Conventional digital subtraction …

OBJECTIVE: Subarachnoid hemorrhage (SAH), which can cause mortality and severe
morbidity, is a serious condition whose underlying cause must be determined. We aimed to …

BACKGROUND AND PURPOSE: During surgery of symptomatic aneurysms, additional
small angiographic occult aneurysms are commonly found. With 3D rotational angiography …

PURPOSE To compare rotational angiography with conventional digital subtraction
angiography in the assessment of cerebral aneurysms. METHODS Conventional digital …

RATIONALE AND OBJECTIVES: The aim of this study was to compare conventional two-
dimensional (2D) digital subtraction angiography (DSA) with three-dimensional (3D) …

BACKGROUND AND PURPOSE: CTA is becoming the frontline modality to reveal
aneurysms in patients with SAH. However, in about 20% of SAH patients no aneurysm is …
