The study of cataclysmic variables (CVs), and in particular of the evolution
of their accretion discs throughout their different brightness states, has
benefited largely from the use of indirect imaging techniques. I report on the
latest results obtained from Doppler tomography of CVs concentrating mainly on
results published since the 2000 Astrotomography meeting in Brussels. Emphasis
is given to the spiral structures found in the accretion discs of some CVs, to
the evolution of these structures throughout quiescence and outburst, and to
our search for them in more systems.Comment: 4 pages, 1 figure. Accepted for publication in AN. Proceedings of the
