Introduction
Computed tomography (CT) perfusion is extremely useful and accurate in
assessing early ischemic changes in the brain. It is therefore accepted in most emergency
departments worldwide as the method of choice for investigating patients with suspected stroke. In
other body areas, CT perfusion is still a research tool that is promising although limited by
technical factors.
Regarding the liver, attempts have been made to apply CT perfusion in the characterization
of focal liver lesions and in their follow-up after treatment. A rapid communication, published in
the October 2008 issue of the
World Journal of Gastroenterology [

], reported that CT perfusion can be used to assess changes in tumor perfusion after
transarterial chemoembolization (TACE).
