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.
This is a protocol.
