Yin Y, et al. - The researchers carried out a systematic review and meta-analysis to compare the diagnostic values of ¹⁸F-fluorodeoxyglucose positron emission tomography (FDG-PET) and magnetic resonance imaging (MRI) in detecting spondylitis via systematically search of online PubMed, Embase, and Cochrane Library databases through September 2017 for studies comparing the diagnostic values of ¹⁸F-FDG-PET and MRI. As compared to MRI, the summary results of sensitivity, specificity, positive likelihood ratio (PLR), diagnostic odds ratio (DOR), and area under the summary receiver operating characteristic (SROC) were higher in ¹⁸F-FDG-PET. It was noted that negative likelihood ratio (NLR) was lower in ¹⁸F-FDG-PET than in MRI. In detecting spondylitis, ¹⁸F-FDG-PET had higher diagnostic value compared with MRI.
