Three-dimensional digital subtraction angiography vs two-dimensional digital subtraction angiography for detection of ruptured intracranial aneurysms: A study of 86 aneurysms

Abstract

3D-DSA, especially volume-rendering images, tends to depict ruptured intracranial aneurysms bigger than 2D-DSA. This is particularly true with cerebral aneurysms that are < 5 mm in size and are located in the anterior circulation, especially ICA and ACA territories.

Virtual angioscopy by means of three-dimensional rotational angiography of the aortoiliac arteries

“…b Endoview that shows the proximal (yellow arrow) and distal (blue arrow) radiopaque markers of the nitinol stent and the catheter. uation of intracranial and extracranial arteries [6][7][8][9][10][11][12][13][14][15][16][17][18], together with the usefulness of the technique in planning some types of endovascular treatment such as stent deployment [13][14][15]. Virtual angioscopy is a new modality for imaging the arterial vessels.…”

“…Only one paper reported on a preliminary experience with 3DRA [18]. In this study, we have analysed the contribution of virtual angioscopic reconstructions starting from 3DRA and have shown that the quality of these images is satisfactory in a high percentage of ed extracraniche [6][7][8][9][10][11][12][13][14][15][16][17] e il contributo di questa tecnica nella programmazione di alcuni tipi di trattamenti endovascolari cosi come nel posizionamento degli stent [13][14][15].…”

“…The 3D reconstruction allows lesion appreciation from innominate oblique views, providing all the information needed for definition of either surgical or endovascular treatment. This technique was originally created to investigate intracranial vessels [6][7][8][9], but increasing numbers of studies have also reported its use at the extracranial level [10][11][12][13][14][15][16][17]. The final 3D reconstruction is characterised by high accuracy and precise visualisation of microsized vessel structures.…”

“…L'elaborazione 3D consente la valutazione di lesioni da un numero illimitato di viste fornendo così tutte le informazioni necessarie per la definizione dell'eventuale terapia chirurgica o endovascolare. Questa tecnica è stata inizialmente sviluppata per la valutazione dei vasi intracranici [6][7][8][9], ma ci sono iniziali esperienze anche a livello extracranico [10][11][12][13][14][15][16][17]. La ricostruzione tridimensionale è caratterizzata da un'elevata accuratezza e precisa rappresentazione di vasi di diametro estremamente piccolo.…”

Computed Tomographic Angiography: Diagnostic Procedure of Choice in the Management of Subarachnoid Hemorrhage in the Elderly Patient?

“…Most neurovascular centers also have 3D rotational angiography (3D-DSA). 3D-DSA provides more detailed information in the evaluation of cerebral aneurysms than 2D-DSA [38, 39]. However, in our neurosurgical department, 3D-DSA is not provided as a first-line tool in elderly patients.…”
