Gated myocardial perfusion imaging (G-MPI) is regularly performed using single-photon emission computed tomography. The objective of this study was to evaluate the clinical value of 99Tcm-methoxyisobutylisonitrile (MIBI) myocardial imaging in glycogen storage disease (GSD).


99Tcm-MIBI G-MPI was performed in nine patients with clinically proven GSD. QGS quantitative software was used for processing and interpretation. Left ventricular ejection fraction (LVEF), end-diastolic volume (EDV) and end-systolic volume (ESV) were automatically generated. The myocardium was divided into seven segments, 20 sub-segments and a five-point scoring system was used.


Seven out of nine cases were abnormal and the positive rate of G-MPI was 77.8 %. Sixty-two sub-segments of injured myocardium were detected in 140 sub-segments of seven abnormal patients. One injured segment was observed in one patient (14.3 %), two segments were detected in two patients (28.6 %) and three or more abnormal segments were observed in four patients (57.1 %).


99Tcm-MIBI G-MPI can detect myocardial damage in GSD as a non-invasive method. It plays an important role in the clinic.
