But it is very difficult to observe the blood flow in the subendocardial. Fortunately the high speed CCD microscope provides a powerful tool.
但是，观测心内膜血流是十分困难的，而高速CCD显微镜为观测提供了有力的工具。
The myocardium beneath the endocardial surface at the top demonstrates pale fibrosis with collagenization following healing of a subendocardial myocardial infarction.
图上方心内膜下的心肌可见苍白色纤维化，是心内膜下心肌梗死治疗后形成的。
Purpose: This study was designed to investigate the value of myocardial contrast echocardiography (MCE) for measuring the coronary blood flow reserve and subendocardial perfusion.
目的：探讨心肌声学造影定量冠脉血流储备及心内膜下心肌灌注的意义。
Results There was no significant difference in resting subendocardial MBF between 40 segments with resting regional wall motion abnormality (RWMA, %WT<30%) and 42 segments without RWMA (P>0.05).
结果静息状态下，40个室壁运动异常（RWMA）心肌节段与42个非RWMA间的心内膜下MBF无明显差异。
