Overview
123I-metaiodobenzylguanidine (MIBG) scintigraphy coupled with CT scan imaging can be used for the localization of distant metastasis of pheochromocytoma.
Other Imaging Findings
Other imaging studies may include:[1]
- 123I-metaiodobenzylguanidine (MIBG) scintigraphy: In case of negative CT and MRI. The uptake of the compound by tumor cells is analogous to norepinephrine uptake by adrenergic tissues[2]
- 111In-octreotide scintigraphy[3]
- 18F-fluorodeoxyglucose positron emission tomography is more sensitive than I-MIBG
- PET CT has high sensitivity for small lesions and is more sensitive than I-MIBG
- Adrenal venous sampling (AVS) has high false positive results[4]
- Image-guided needle biopsy of suspected pheochromocytoma may be done but it is associated with many surgical complications[5][6]
