3D rotational angiography: use of propeller rotation for the evaluation of intracranial aneurysms.

Clinical usefulness of unsubtracted 3D digital angiography compared with rotational digital angiography in the pretreatment evaluation of intracranial aneurysms.

BACKGROUND AND PURPOSE Three-dimensional digital subtraction angiography (DSA) is useful as a supplement to 2D DSA in the pretreatment evaluation of intracranial aneurysms. However, the clinical efficacy of 3D digital angiography (DA) that is generated from unsubtracted rotational images has not been established. The purpose of this study was to assess whether 3D DA provides additional useful i...

3D rotational angiography (3DRA) for surgical planning and post-surgical evaluation of intracranial aneurysms

3D Rotational Angiography in Follow-Up of Clipped Intracranial Aneurysms

Introduction. 3D Rotational Angiography (RA) is indispensable for evaluation of intracranial aneurysms, providing infinite viewing angles and defining the aneurysm morphology. Its role in follow-up of clipped aneurysms remains unclear. We aimed to compare the aneurysm residue/recurrence detection rate of 3D RA with 2D digital subtraction angiography (DSA). Methods. 47 patients harboring 54 clip...

Intravenous 3D digital subtraction angiography in the diagnosis of unruptured intracranial aneurysms.

Recent progress in digital subtraction angiography (DSA) devices makes it possible to perform rotational angiography with high resolution and high sensitivity. We tried intravenous (IV) 3D DSA in patients who had undergone MR angiography (MRA) suggestive of unruptured intracranial aneurysms. IV 3D DSA can be used as an alternative method for imaging unruptured intracranial aneurysms suggested o...

Comparison of 2D and 3D digital subtraction angiography in evaluation of intracranial aneurysms.

BACKGROUND AND PURPOSE Although digital subtraction angiography (DSA) is considered the criterion standard for depiction of intracranial aneurysms, it is often difficult to determine the relationship of overlapping vessels to aneurysms when using 2D DSA. We compared 2D and 3D DSA in evaluation of intracranial aneurysms. METHODS Thirty-six consecutive patients with cerebral aneurysms underwent...
