Preface
Over the last 8 years I have been archiving and cataloging angiographic images that I obtained using one of the first three-dimensional rotational angiographic systems. My career has allowed me to use angiographic cut film, two-dimensional digital subtraction angiography (2D DSA), and now three-dimensional rotational angiography (3DRA). This revolutionary angiographic technique maximizes diagnostic accuracy and provides an invaluable teaching tool for anyone interested in learning more about cerebral vascular anatomy.
The 3D representation of the human neurovascular system represents an enormous step forward in our ability to display this complex anatomy. Our goal in anatomical imaging is to try to recreate the in vivo status as close to its natural state as possible.
Until recently we have had to rely solely on 2D representation of this anatomy. Only recently have certain techniques emerged that can display the natural anatomic state in a 3D display. These techniques include 3D rotational catheter angiography, CT angiography (CTA), and magnetic resonance angiography.
There are three reasons why it is important to have the ability to view vascular anatomy in a 3D display. First, a 3D display is a more accurate representation of the pre-existing anatomy of the subject and can only improve our diagnostic accuracy. The evolution of imaging techniques over the last few decades has been aimed at achieving the most accurate reproduction of the anatomy and pathology possible.
The second reason for the importance of 3D display is a natural extension of the first reason. Only through analysis of the true/real anatomic composition of our subject can we make the most appropriate recommendations regarding prognosis and potential interventions (conservative management, traditional surgery, and/or endovascular surgery).
