  • * Patients with more than 1 scan during study period may be listed in different categories (i.e., patients scanned at both diagnosis and follow-up or patients with multiple follow-up scans with different results).

  • 123I-MIBG > 18F-FDG = numbers of scans and patients for which 123I-MIBG detected more lesions; pts = patients; 18F-FDG > 123I-MIBG = numbers of scans and patients for which 18F-FDG detected more lesions; Equivalent = numbers of scans and patients for which 123I-MIBG and 18F-FDG detected similar or complementary numbers and distributions of lesions; Negative = numbers of scans and patients for which 123I-MIBG and 18F-FDG study results were normal.
