Fig. 1From: Skeletal standardized uptake values obtained by quantitative SPECT/CT as an osteoblastic biomarker for the discrimination of active bone metastasis in prostate cancerA representative whole-body (WB) image (a, b), a maximum intensity projections (MIP) image (c), and coronal and sagittal SPECT images (d, e) in the same standardized uptake value (SUV) window range (0–15). Note the enhanced contrast of uptake in regions of bone metastases (solid arrows) compared to regions of degenerative changes (dotted arrows). Lesions indicated as M1 to M4 were bone metastases, and those indicated as D1 and D2 were degenerative changes. Corresponding SUVmax measurements were M1, 117.9; M2, 90.80; M3, 50.90; M4, 39.90; D1, 24.08; D2, 13.26, and MV measurements were M1, 8.87; M2, 19.35; M3, 7.25; M4, 2.73; D1, 15.80; and D2, 9.18, respectivelyBack to article page
