  • VA = visual analysis; FDOPA = 6-18F-fluorodopa PET; pheo = pheochromocytoma; pos = positive; MIBG = 131I-MIBG; ND = not done; ab = abdominal; PGL = paraganglioma; SRS = somatostatin receptor scintigraphy; ce = cervical; gl = glomic; neg = negative; RET = RET protooncogene; me = mediastinal; LN = lymph node; HMDP = 99mTc-HMDP; HMDP = hydroxymethylenediphosphonate.

  • * Comparison between 18F-FDG PET and SPECT (131I-metaiodobenzylguanidine [MIBG] or SRS) and 6-18F-fluorodopa PET studies in terms of number of tumor sites. = indicates equivalent number of tumor sites on 18F-FDG PET; < indicates lower number of tumor sites on 18F-FDG PET; > indicates higher number of tumor sites on 18F-FDG PET.
