Abstract

Imaging actually plays a pivotal role in the diagnosis of liver diseases. The multi-phase contrast enhanced CT scan is an important diagnostic tool in the hand of the radiologists. It is also useful in staging, preoperative planning and follow-up of patients with hepatic diseases. The use of iodinated contrast medium is essential for CT diagnosis of liver diseases. The liver scanning protocol must be established on the basis of the clinical question and of the diagnostic suspicion. It consists in different phases: non-enhanced, early arterial, late arterial, portal-venous, delayed/equilibrium and ultra-delayed phases. All these phases are not usually performed in each patient for different reasons, first of all radiation exposure and clinical suspicion. For the diagnosis of liver diseases, it is essential to know what are the most common diseases affecting the liver and their typical CT imaging features. As regards as focal liver lesions there are three important macro-groups: hepatic cystic lesions, benign hepatic tumours and malignant tumours.
