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

Figure 1 A 59-year-old man presented with hematuria and difficulty urination, S. PSA > 100 ng/dL, and a suspicious lesion in the prostate on magnetic resonance imaging. A and B: ^99mTc-PSMA planar images show increased heterogeneous tracer uptake in the prostate gland region (orange arrows) and likely abdomino-pelvic lymph nodes (green arrows); C-G: Coronal, sagittal, and axial SPECT-CT fused images show increased heterogenous tracer uptake in the enlarged prostate gland (orange arrows) and abdomino-pelvic lymph nodes (green arrows). Biopsy from the prostate was positive for primary adenocarcinoma (GS-5+5).
