PHAEOCHROMOCYTOMA-IMAGING
SUMMARY
1. If the biochemical tests suggest a pheo, perform CT or MRI of the abdomen and pelvis to find the tumour.
2. If imaging does not show a tumor and you still suspect one given the screening tests and history,
3. Look for the tumor using a radioactive tracer (I123, metaiodoben zylguanidine [MIBG] scintigraphy, a norepinephrine analog that concentrates in adrenals and pheos),
4. PET scan, or total body MRI.
