Aims and objectives
To illustrate and to review usefulness of rotational DSA with dual volume visualization in the evaluation of neurovascular disease. Summary: Rotational DSA is useful imaging tool in the evaluation of neurovascular disease.
This exhibit illustrates basics including display modes and radiation dose,
and their clinical application in the evaluation of neurovascular disease inclulding intracranial aneurysm,
and spinal vascular malformation.
Methods and materials
# Contents :3D Rotational DSA (3D RA) with Dual Volume Visualization Basics and Radiation Dose Clinical application Intracranial aneurysm bAVM and dAVF spinal Vascular malformation # 3D Rotational Angiography (3D RA) Performed using C-arm with rotation around the patient in a few seconds Provides better understanding of vessel architecture of 1)Aneurysm : Pretreatment: evaluating the potential for EVT,
finding a good working view,
performing accurate measurement 1 ,
depict more aneurysms 2 …...
3D RA with DUAL VOLUME VISUALIZATION ALSO HELPFUL WHEN … # Aneurysm: Virtual Localization of Distal Dural Ring (Figure 5) Visualization of virtual plane of DDR and localization of the paraclinoid ICA aneurysm in relation to the DDR is feasible with 3D RA Lee et al.,
Neurointervention 2010;5:85-90 # Dural AVF - Benefit of Rotational DSA The presence of shunted venous pouch is a common angioarchitecture of transverse sinus dAVFs,
and identification of this pouch with rotational angiography...
3D RA : Dual Volume Visualization Ability to separately illustrate contrast-filled vessels vs mask with soft tissue,
stents and coils Radiation dose (dual rotation) similar to bi-plane evaluation of single vessel by 2D DSAs Helpful in the evaluation of neurovascular ds including aneurysm,
