“…The operator has to identify the most suitable acoustic window to evaluate the lesion and simply observe tumour enhancement after the injection of contrast agent without moving the transducer from the initial position. Correct image interpretation is less straightforward and depends on the reader's experience [30]. One limitation of CEUS in comparison to multiphase CT and MR imaging is the fact that only one liver lesion can be examined at a time as the transducer has to be kept still during the examination, and further contrast injections are necessary to characterize additional liver tumours.…”
