报告利用SPECT~(201)Tl心肌显像技术,定量分析先天性心肌病患儿右室收缩压变化及其临床意义.病例:34例儿童(男18例、女16例、平均年龄7.9±2.9岁)均患不同的先天性心脏病,全部患儿均经~(201)Tl SPECT心肌显像及心导管检查确诊.仪器与方法:Siemens ZLC-7500Digitrac,平行孔高分辨准直器.静脉快速注入~(201)TlCl 37～56MBq(1～1.5mCi),5min后行SPECT心肌显像.探头旋转180°(RAO30°～LPO60°),图像采集180°/5.5°帧/30～40s,矩阵64×64,放大倍数1.5.图像重建后断层厚度4mm.在短轴图像上最佳区分室间隔
The report quantitatively analyzed the changes of right ventricular systolic pressure in children with congenital cardiomyopathy using SPECT ~ (201) Tl myocardial imaging and its clinical significance.Methods: 34 children (18 males and 16 females, mean age 7.9 ± 2.9 Year old) had different congenital heart disease, all children were confirmed by ~ (201) Tl SPECT myocardial imaging and cardiac catheterization.METHODS AND METHODS: Siemens ZLC-7500 Digitrac, collimator high resolution collimator SPECT myocardial imaging was performed after ~ (201) TlCl 37 ~ 56MBq (1 ~ 1.5mCi) injection, and 5min later, the probe rotated 180 ° (RAO30 ° ~ LPO60 °) and the image was captured at 180 ° / 5.5 ° frame / 30 ~ 64 × 64, magnification 1.5. Image reconstruction thickness of the fault 4mm. In the short axis images on the best distinction between ventricular septum
