本文作者报告了用~(201)T1心肌闪烁图(~(201)T1-MP1)测定~(201)T1右室心肌摄取率检出肥厚型心肌病(HCM)右室病变的研究。对象及方法:以正常组11例、高血压病组10例和肥厚型心肌病组9例为研究对象。用M型超声心动图检查这些组的室间隔厚度,分别为0.94±0.16CM、1.46±0.20CM和2.06±0.30CM,各组之间差别显著(P<0.01)。全部病例用脚踏车功力计进行次最大负荷运动,当受检者心率达到标准(190-年龄/分)时,从肘静脉注射~(201)T12.0mCi,以同样强度的负荷继续运动1分钟。3组之间运动负荷的压力率(Pressure rate)
The authors report the detection of right ventricular hypertrophy in patients with hypertrophic cardiomyopathy (HCM) using ~ (201) T1 myocardial perfusion imaging (~ (201) T1-MP1). Subjects and Methods: The study group consisted of 11 normal subjects, 10 hypertensive patients and 9 hypertrophic cardiomyopathy patients. The interventricular septum thickness of these groups was 0.94 ± 0.16CM, 1.46 ± 0.20CM and 2.06 ± 0.30CM with M-mode echocardiography. There was a significant difference between the groups (P <0.01). All cases were submaximally loaded with a bicycle power meter. When the subject’s heart rate reached the standard (190-age / min), ~ (201) T12.0mCi was injected from the elbow vein and continued for 1 minute with the same intensity load. Pressure load ratio between the three groups
