To investigate the value of CT arterial enhancement fraction (AEF) in the post-processing technique of liver perfusion-like phase III enhanced CT scan in evaluating the degree of liver function impairment in patients with hepatitis B cirrhosis. ⋯ AEF boasts the value of differentiating liver fibrosis and cirrhosis, and of evaluating the degree of liver function impairment in patients with hepatitis B cirrhosis.

To compare the diagnostic efficacy of fine needle aspiration (FNA) and core needle biopsy (CNB) for metastatic lymph nodes guided by contrast-enhanced ultrasound (CEUS), and to provide reference for clinical selection of puncture methods. ⋯ CEUS can guide puncture and improve diagnosis accuracy. No statistical difference can be seen in the diagnostic efficacy of CNB and FNA for metastatic lymph nodes, CNB can provide more diagnostic information, while FNA can replace CNB for metastatic lymph nodes adjacent to blood vessels and difficult to operate.
