In contemporary years, the imaging-based analysis of mass liver lesions has develop into more and more advanced end result of the quantity and morphological variability of lesions that glossy imaging strategies are at present capable of show. If the sensitivity in detection has tremendously elevated, characterisation has remained tricky and represents a serious problem for the clinician.

The availability of blood-pool distinction brokers for ultrasound (US), specifically second-generation US distinction brokers according to perfluorocarbon- or sulfur-hexafluoride-filled microbubbles, and the improvement of contrast-specific software program and applied sciences have spread out new views either for the instant characterisation of any mass lesion detected within the liver and for expanding the sensitivity people within the detection of liver metastases.

Taking into consideration the good impression of this new expertise on scientific perform, the eu Federation of Societies for Ultrasound in medication and Biology (EFSUMB) organised, in January 2004, in Rotterdam, a consensus assembly of specialists which will boost directions for using US distinction brokers within the prognosis of liver ailments . those instructions, in addition to discussions of extra advances within the scientific software of contrast-enhanced harmonic US are awarded during this e-book through an the world over popular staff of specialists. The ebook represents offers a huge start line for medical implementation of this new diagnostic procedure.

Example text

In the same patient as in Fig. 3, an additional small HCC was also detected in between segment III and II. This lesion was not seen on baseline imaging even during the review of the cineloops acquired during the examination. a, b The lesion strongly enhanced during arterial phase (a, arrow) and became hypoechoic during late phase (b). c CT confirmed the presence of this typical HCC a b c in this patient population, where any focal lesion over 2 cm should be considered as a potential HCC. They typically do not show any vascularity at color Doppler US.

New algorithms should be developed to take into account the role of CEUS. However, the imaging technique is evolving very quickly and results between series are not easily comparable. The problem of truly hypovascular HCCs persists particularly in nodules of 1 to >2 cm. If a hypervascular pattern is detected by CEUS (even if missed by CT or MRI), an aggressive policy should be proposed that includes liver biopsy [21].
