2D-PA offers an objective approach to quantify the immediate perfusion reduction of embolized tumor tissue following DEB-TACE and may therefore be used to monitor peri-interventional stasis and to quantify technical success.
Today, hepatocellular carcinoma (HCC) represents the leading cause of death in patients with liver cirrhosis; in most western countries the incidence is also expected to increase further. Due to insufficient surveillance of patients at risk, most cases are diagnosed in an intermediate to advanced stage, leading-together with the underlying liver cirrhosis-to limited therapeutic options and a dismal prognosis. Therefore, classification according to stage and interdisciplinary treatment decisions in experienced centers are of paramount importance to provide an individualized treatment plan when considering potentially curative (resection, liver transplantation, local ablation) and palliative (transarterial approaches, sorafenib) treatment options. There is hope that the prognosis of patients with HCC can be improved in the near future by better prevention, stringent surveillance, multimodality treatment approaches, and an expansion of personalized medicine.
Radiology plays an important role in introduction and use of information technology (IT) systems in the daily clinical routine. The radiology information system (RIS) and picture archiving and communication system (PACS) are the main systems used in a digital radiology department. In this article the basic principles and functions of these systems and trends in development are described.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
