Objective To systematically review the diagnostic value of gadolinium ethoxybenzyl diethylenetriamine pentaacetic acid (Gd-EOB-DTPA) for liver metastases. Methods We searched databases including CNKI, CBM, VIP, WanFang Data, PubMed, EMbase and The Cochrane Library from January 2011 to December 2014 to collect diagnostic tests about Gd-EOB-DTPA for liver metastases. Two reviewers independently screened literature, extracted data, and assessed the risk of bias of included studies by using the QUADAS-2 (Quality Assessment of Diagnostic Accuracy Studies-2) tool. Then, meta-analysis was performed by using Stata 12.0 software. Results A total of 15 studies from seven countries were included, involving 2 040 nodules from 701 patients. The results of meta-analysis showed that, the pooled sensitivity (Sen), specificity (Spe), positive likelihood ratio (+LR), negative likelihood ratio (-LR) and diagnostic odds ratio (DOR) of Gd-EOB-DTPA for liver metastases were 0.92 (95%CI 0.89 to 0.95), 0.94 (95%CI 0.89 to 0.97), 14.51 (95%CI 8.01 to 26.28), 0.08 (95%CI 0.06 to 0.12), and 177.98 (95%CI 89.50 to 353.94), respectively. The area under curve (AUC) of SROC was 0.97 (95%CI 0.95 to 0.98). The results of subgroup analysis showed that Gd-EOB-DTPA had better Sen in nodules >10 mm than the nodules ≤10 mm in diameter (>10 mm: pooled Sen=0.97, 95%CI 0.94 to 0.99; ≤10 mm: pooled Sen=0.75, 95%CI 0.65 to 0.85; P<0.001); The 3.0T MR had better Sen in diagnosing liver metastases compared with 1.5T MR (3.0T: pooled Sen=0.95, 95%CI 0.92 to 0.97; 1.5T: pooled Sen=0.90, 95%CI 0.87 to 0.94; P<0.001). Conclusion GdEOB-DTPA is of value for the detection of liver metastases. In particular, it is of high sensitivity for the detection of nodules larger than 10 mm, and for the cases using 3.0T high-field MR system. Due to limited quantity and quality of the included studies, more high-quality studies are required to verify the above conclusion.
