On planar images (A, B) it is difficult to distinguish activity in the pelvis as being prostatic uptake or urinary bladder activity. On SPECT images (C) uptake is confidently attributed to the prostate (tip of blue arrows on coronal and sagittal views), with an adjacent focus (C; crosshairs on coronal, trans-axial, and sagittal views) that observers queried as being in an adjacent lymph node or seminal vesicle. On SPECT/CT (D) uptake is localized to the prostate gland (tip of red arrows) and the left seminal vesicle (crosshairs)
