Sažetak
This is a protocol for a Cochrane Review (diagnostic). The objectives are as follows: To determine the diagnostic accuracy of contrast- enhanced ultrasound (CEUS) versus contrast- enhanced computed tomography (CECT), magnetic resonance imaging (MRI), and fluro-18- deoxyglucose positron emission tomography-computed tomography (18F-FDG PET/CT) for diagnosing liver metastases in people with newly diagnosed colorectal cancer. Secondary objectives We plan to investigate the following potential sources of heterogeneity. • Study design (prospective compared to retrospective) • Study date (studies conducted before the year 2000 compared to studies conducted aMer the year 2000) due to advancements in technology and change in diagnostic criteria • Participant selection (participants recruited from planned screening programmes compared to clinical setting) • Proportion of participants with resectable liver metastasis • Maximum diameter of the largest liver lesion • DiNerences in operator skills in CEUS performance, assessed by years of experience • DiNerent reference standards (studies using pathology of resected liver compared to studies using histology of hepatic lesion)
