Meta-Analysis Sizes Up FAPI PET/CT Accuracy for Peritoneal Metastasis Detection

A new meta-analysis examines fibroblast activation protein inhibitor (FAPI) PET/CT for detecting peritoneal metastases, suggesting diagnostic performance advantages over conventional imaging — though exact pooled sensitivity/specificity figures were not reported in the source ex…

• Study design is a meta-analysis of FAPI PET/CT for peritoneal metastasis detection; individual study count, total patient n, and pooled accuracy metrics are not available in the source snippet.
• FAPI-targeted PET/CT leverages tumor stromal uptake rather than glucose metabolism, potentially improving detection of lesions that are FDG-avid poorly or small-volume peritoneal disease.
• Key limitation cannot be specified without the full data; meta-analyses of PET tracers commonly face heterogeneity in reference standards and patient populations across included studies.
