Abstract:
:We present two cases with mitochondrial encephalopathy with lactic acidosis and strokelike episodes (MELAS), which showed both increased and decreased accumulation of N-isopropyl-p-(123I)-iodoamphetamine (123I-IMP) in single photon emission computed tomography (SPECT). The increased accumulation of the tracer occurred, before low density appeared on conventional computed tomography, suggesting that 123I-IMP SPECT may be useful in pathophysiological study of MELAS.
