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

Figure 4 A 75-year-old man presented with hematuria and painful micturition, S. PSA 48.8 ng/dL, and G-III prostatomegaly on USG. A and B: ^99mTc-PSMA planar images show mild diffuse tracer uptake in the prostate gland region (orange arrows), physiological uptake in the salivary glands, liver, spleen, kidneys, and bowel loops, and urinary catheter in situ with no significant bladder activity; C and D: Axial CT and SPECT-CT fused images show prostatomegaly with mild diffuse tracer uptake. Biopsy from the prostate was negative for malignancy with benign hyperplasia.
