The myocardium and brain SPECT findings in organophosphate poisoning.

Abstract

A case of organophosphate poisoning is presented by using Tc-99m HMPAO (hexamethyl propylenamine oxime) brain SPECT (single photon emission computer tomography) and Tc-99m Sestamibi myocardial SPECT findings in the acute recovery and delayed phases. On the 4th day, brain SPECT imaging showed the perfusion defects in the left parietal lobe of the brain. On the 5th day myocardium scintigraphy also revealed the anterolateral wall perfusion defect. The myocardial defect became more prominent but brain defect was smaller than before, on the 19th day of the therapy. Two months later, on the third examinations of the brain and myocardium, their imagings were both normal.
