Figure 1
Figure shows an example of relapse in the prostatic region (green arrow) and how it is seen, respectively, in the delayed (upper row) and early images (lower row). Note in the early images the visualization of the iliac vessels, the absent accumulation of radioactive urine in ureters, bladder, and urethra, and the pathologic accumulation of the tracer in the prostatic fossa and the right iliac nodes. In the late images (Figure 1, MIP) a bone lesion has been also depicted in S1 outside the FOV (field of view) of the early images (black arrow). Upper left: delayed fused whole body PET/CT images. Upper right: delayed whole body MIP (multiple intensity projection) images. Low left: early fused PET/CT images. Low right: MIP images of the pelvic region (1 bed position).
