Application of ¹²³I-MIBG myocardial maximum standardized uptake value to characterize cardiac function in patients with pheochromocytoma: comparison with echocardiography.

ABSTRACT:

Purpose

This study examined the usefulness of the maximum standardized uptake value (SUVmax) of myocardial [¹²³I]-metaiodobenzylguanidine ([¹²³I]-MIBG) to characterize myocardial function by comparing it with echocardiographic parameters in patients with pheochromocytoma.

Materials and methods

This study included 18 patients with pheochromocytoma who underwent both planar and [¹²³I]-MIBG single-photon emission computed tomography/computed tomography scans and echocardiography before surgery. Myocardial [¹²³I]-MIBG visibility and SUVmax were compared with echocardiographic parameters related to systolic and diastolic functions. The Mann-Whitney U test, Fisher exact test, or Spearman rank correlation assessed differences or relations
