Our main goal of this meta-analytical analysis was to evaluate the diagnostic effectiveness of prostate-specific membrane antigen (PSMA) positron emission tomography (PET)/computed tomography (CT) against multiparametric magnetic resonance imaging (mpMRI) in the context of identifying biochemical recurrence in patients with prostate cancer (PCa). A thorough search covering articles published until March 2023 was carried out across major databases such as PubMed, Embase, and Web of Science. Studies examining the direct comparison of PSMA PET/CT and mpMRI in patients with PCa suffering biochemical recurrence were included in the inclusion criteria. Using the renowned Quality Assessment of Diagnostic Performance Studies-2 technique, each study's methodological rigor was assessed. We analyzed data from six eligible studies involving 290 patients in total. The combined data showed that for PSMA PET/CT and mpMRI, respectively, the pooled overall detection rates for recurrent PCa after definitive treatment were 0.69 (95% confidence interval [CI]: 0.45–0.89) and 0.70 (95% CI: 0.44–0.91). The detection rates for local recurrence were specifically 0.52 (95% CI: 0.39–0.65) and 0.62 (95% CI: 0.31–0.89), while they were 0.50 (95% CI: 0.26–0.74) and 0.32 (95% CI: 0.18–0.48) for lymph node metastasis. Notably, there was no discernible difference between the two imaging modalities in terms of the overall detection rate (P = 0.95). The detection rates for local recurrence and lymph node metastasis did not differ statistically significantly (P = 0.55, 0.23). The performance of PSMA PET/CT and mpMRI in identifying biochemical recurrence in PCa appears to be comparable. However, the meta-analysis' findings came from research with modest sample sizes. In this context, more extensive research should be conducted in the future. • Pooled detection rates for recurrent prostate cancer (PCa): 0.69 with prostate-specific membrane antigen (PSMA) positron emission tomography (PET)/computed tomography (CT), 0.70 with multiparametric magnetic resonance imaging (mpMRI). • PSMA PET/CT and mpMRI perform equally in detecting PCa recurrence. • This article is a head-to-head comparative meta-analysis.
