Haemodynamic events and localised parenchymal changes following transcatheter arterial chemoembolisation for hepatic malignancy: interpretation of imaging findings

Following transcatheter arterial chemoembolisation (TACE), the appearances on CT or MR images are largely related to the chemical and ischaemic insults to the portal tract. Understanding the mechanism of TACE-induced changes is essential for radiologists in order to determine the therapeutic effect as well as to distinguish these changes from recurrent tumours. This pictorial review illustrates the haemodynamic and substantial parenchymal changes related to TACE for hepatic malignancy.
