用单光子断层扫描术（ＳＰＥＣＴ）检查经血清学证实的病毒性心肌炎患儿２４例，并与同年龄、同体重健康儿童配对对比，发现ＬＶＥＦ下降占２９．２％，ＬＰＥＲ下降占４５．７％，ＬＰＦＲ下降占１６．７％，ＲＶＥＦ下降占８．３％，ＲＰＥＲ下降占１２．５％，ＲＰＦＲ下降占１２．５％，表明心肌炎左心功能受累重于右心功能，收缩功能受累重于舒张功能。通过时相分析ＬＶＷ增厚占４３．４％，ＬＶＰ增宽占２０．８％，表明心肌炎患儿心肌收缩不协调。通过室壁运动检查，室壁运动减弱占２５％。证实病毒性心肌炎ＳＰＥＣＴ有显著改变，ＳＰＥＣＴ检查有助于心肌炎的诊断和病情了解，
Twenty-four patients with serologically confirmed viral myocarditis were examined by single photon tomography (SPECT), and compared with paired healthy children of the same age and same weight, 29.2% of LVEF and 45.7 of LPER were found %, LPFR decreased 16.7%, RVEF decreased 8.3%, RPER decreased 12.5%, RPFR decreased 12.5%, indicating that left ventricular dysfunction in myocarditis is more important than right ventricular function, systolic dysfunction In diastolic function. LVW thickening accounted for 43.4% by phase analysis, LVP widened accounted for 20.8%, indicating that myocardial contractions in children with myocarditis are not coordinated. Wall motion examination through wall, wall motion weakened 25%. Confirmed that viral myocarditis SPECT significant change, SPECT examination contributes to the diagnosis of myocarditis and disease understanding,
