Objectives:
To develop guidelines for the noninvasive imaging assessment of focal liver lesions comparing different imaging modalities focused on (i) evaluating the imaging techniques in terms of (a) diagnostic accuracy; (b) role in the management of oncologic patients; (c) follow-up of benign lesions; and (ii) developing standard procedure for their use in patients with focal liver lesions that require targeted diagnostic characterization.
Methods:
An explicit search strategy was used to conduct a systematic review of the literature in the English language from January 2000 to October 2007; the search covered PubMed, Embase, Pascal, SciSearch, and Cochrane Library databases. A panel of experts evaluated the selected studies and conveyed their view.
Results:
The online search yielded 4960 titles and abstracts from which 176 studies were considered suitable for the final adherence-to-guidelines topic evaluation. An evidence grading system was not used as the guideline topic and the heterogeneity of the collected data did not fit with the currently used hierarchy of evidence. A panel of experts formulated several recommendations with grade and level which were expressed narratively and nonschematically.
Conclusion:
The recommendations reported in the study are based on an extensive literature evaluation and were developed by considering the appropriateness of the choice of the imaging techniques while noninvasively detecting and characterizing focal liver lesions.
