Sequential patient scan (P1) of 67-y-old patient with biochemical relapse (PSA level, 6.7 ng/mL) 1.8 y after curative radiotherapy. Maximum-intensity projections (upper row) and axial slices (middle and lower row) of early rapid scan (A) and scans after 1 h (B), 2 h (C), and 4 h (D) show increased uptake in rib metastasis (A–D, arrows) and physiologic uptake in lacrimal glands, salivary glands, liver, spleen, kidneys, and slightly in bowel (A–D). Red dotted arrow in A depicts unspecific uptake in left subclavian vein.
