The MIBG scan has a high specificity and positive predictive value (100%). It confirms the presence of pheochromocytoma in 21 cases (42%), even if the metanephrine is normal in a patient with a ...

Quint LE, Glazer GM, Francis IR, et al. Pheochromocytoma and paraganglioma: comparison of MR imaging with CT and I-131 MIBG scintagraphy. Radiology . 1987;165:89-93. Sawka A, et al.

In the described case patient, residual tissue of the pheochromocytoma after the first surgery was difficult to detect owing to an apparent lack of correlation between 123 I-MIBG and MRI–CT scans.

If a mass was found by CT, then mIBG scintigraphy (for a mass >2 cm) or MRI (for a mass <2 cm), should be performed next, regardless of whether such a lesion was a paraganglioma or a pheochromocytoma.

Moreover, CT scans, gallium dotatate scans (a procedure to detect areas of the body where cells are dividing rapidly), an MIBG scan (a procedure used to find neuroendocrine tumor), an MRI, PET scans, ...

In some hospitals, instead of an MIBG scan, you may have a DOTATATE PET scan. This helps to diagnose phaeochromocytoma and to see if it has spread. ... Pheochromocytoma and Paraganglioma H Neumann, WF ...

This patient’s adrenal MRI scan was highly suggestive of a pheochromocytoma with a high signal intensity (hyperintense compared to liver) on T2 weighted images. 123-I-MIBG is taken up into the ...
