Diagnostic performance of 99mTc-PSMA SPECT/CT in primary prostate carcinoma

Figure 6 A 54-year-old man presented with lower urinary tract infections and difficult micturition, S. PSA 17.5 ng/dL, and mild prostatomegaly on USG. A and B: ^99mTc-PSMA planar images show no tracer localization in the prostate gland region (orange arrows), with tracer uptake noted in the urinary bladder; C and D: Axial CT and SPECT-CT fused images show mild prostatomegaly with no significant tracer uptake. Biopsy from the prostate showed benign hyperplasia and was negative for malignancy.
