The detection rate was unaffected by the PSA values <i>(all P > 0.05)</i>.<h4>Conclusion</h4>The diagnostic efficacy of <sup>68</sup>Ga-PSMA-11 PET/CT appears to be equivalent to that of <sup>68</sup>Ga-PSMA-11 PET/MRI in detecting biochemically recurrent prostate cancer. The gene discussed is FOLH1; the disease is prostate carcinoma.
