Neurosurgical Review
|January 1, 1985
Abstract:
Digital subtraction angiography (DSA) has strongly influenced angiographic procedures. Because it is less invasive it has increased the total number of angiographies in all places where it was introduced. The paper gives an introduction to the procedure explaining the roles of "digital" and "subtraction" in DSA. It is written from a technical point of view. The examples are taken from and with the DVI system.
