Digital Arteriography: Ongoing Developments
Digital imaging processing has resulted in a new class of images with high-contrast sensitivity and moderate-contrast resolution, such as computerized tomography and digital subtraction arteriography (DSA) [1–3]. DSA represents the first departure from analog film recording of arteriography since the first arteriogram was performed within weeks of Roentgen’s discovery of the X-ray in 1895. DSA at the University of Wisconsin was first performed in a research laboratory in 1977 and was subsequently offered as a clinical service in 1979. Clinical experience has shown that these DSA images provide, in selected circumstances, a definite advantage over film arteriography.
