Since the introduction and widespread use of abdominal imaging technologies there
has been an increase in the frequency of detection of space-occupying lesions in the
liver. In particular due to the use of ultrasound imaging which is frequently used because
of its safety and non-invasive nature and its accessibility. Liver tumors that are found
by incidence are defined as findings unrelated to the clinical indication for which the
imaging examination was performed. To decide which of these tumors needs therapy
further characterization with highly advanced imaging modalities (magnetic resonance
imaging (MRI)) or needle biopsy is needed. Core needle biopsy is still accepted as the
gold standard for diagnosing tumors in various organs. However, there is an increasing
role for radiology in the diagnosis of focal liver tumors, especially by the use of state-ofthe-
art MRI. Moreover, most hepatic tumors can be diagnosed with confidence by the
use state-of-the-art MRI, which may have consequences for the role of needle biopsy
during work-up of focal liver lesions.
