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 for pheochormocytoma include:^[1]

¹²³I-metaiodobenzylguanidine (MIBG) scintigraphy
- Done in case of negative or inconclusive CT and MRI
- Demonstrates the uptake of the compound by tumor cells which is analogous to norepinephrine uptake by adrenergic tissues^[2]
¹¹¹In-octreotide scintigraphy^[3]
¹⁸F-fluorodeoxyglucose positron emission tomography
- More sensitive than I-MIBG
PET CT
- High sensitivity for small lesions
- More sensitive than I-MIBG
Adrenal venous sampling (AVS)
- High false positive results^[4]
Image-guided needle biopsy
- Associated with many surgical complications^[5]
