At discharge, MCA velocity in severe injury remained below normal 46.2 (43.2-49.0) cm/s, whereas, in moderate and minor injury flow velocity had returned to normal. Correlation (r = 0.46, p less than 0.01) was found between MCA velocity and Glasgow Coma Score (GCS) on admission but not...
5.曲线对比通过Trace捕获的曲线,比较了当iType分别设置成MCA_Poly5和MCA_Spline_Complete时,曲线的不同。MCA_Poly5是5次多项式曲线,曲线会严格通过几个关键点。MCA_Spline_Complete是样条曲线,其曲线比5次多项式曲线的曲率大,过渡更顺滑,但不一定严格经过关键点。另比较了TimeScale和VelocityScale对曲线的影响。相当...
4.激活Axis Tracing,分析运行曲线。 上文中展示的曲线为MCA_Poly5曲线。当把iType设置为MCA_Spline_Natural时,其曲线如下图:
Jennifer J. Barr& Giancarlo Mari Abstract Middle cerebral artery peak systolic velocity (MCA-PSV) has emerged as a noninvasive method of screening for fetal anemia in at-risk fetuses. This technique was initially developed to monitor pregnancies complicated by red cell alloimmunization and to guide...
The effect on the middle cerebral artery blood flow velocity (V MCA ) of moderate and hard physical exercise on an ergometer cycle was examined in 10 healthy volunteers using transcranial Doppler sonography (TCD). During exercise, the heart rate increased by 136% and the systolic blood pressure...
Intrauterine Cocaine Effects on Neonatal Middle Cerebral Artery (MCA) Blood Flow Velocity (BFV)Pediatric Research publishes original papers, invited reviews, and commentaries on the etiologies of diseases of children and disorders of development, extending from molecular biology to epidemiology. Use of ...
ABSTRACT: To evaluate maturational differences in the cerebral artery blood flow velocity characteristics, we measured the middle cerebral (MCA) and basilar artery blood flow velocity and time intervals using a real-time imaging pulsed Doppler system in
Tim adds, "Ordered 9/18. Received 6/19. The car will be tracked after break in but for now. Saw its first National Show (MCA) 4 days after receiving it." The GT350R (like the GT350) has a huge 526 horsepower 5.2L naturally aspirated Flat Plane Crank V8 engine. The "R" is ...
Circulatory arrest during profound hypothermia is followed by a period of low cerebral perfusion, whereby time-averaged MCA BFV is decreased and MCA BFV is absent during diastole. We speculate that this can be explained by an increase in intracranial pressure after brain edema....
