Comparative Accuracy of Intravenous Contrast-enhanced CT versus Noncontrast CT Plus Intravenous Contrast-enhanced CT in the Detection and Characterization of Patients with Hypervascular Liver Metastases

Based on existing evidence, NECT only adds a small incremental value to CECT for detection/characterization of hypervascular liver metastases. Addition of NECT increases patient's exposure to radiation and the number of images available for interpretation.
