项目摘要
DESCRIPTION (Adapted from Applicant's Abstract): This application requests
support to continue the investigators work in developing fetal
magnetocardiography (FMCG) as a new noninvasive technology for obtaining
functional information from the human fetus in utero. FMCG is the only
technique that can assess fetal heart rate and rhythm with high precision, and
thus could have a significant impact on perinatal science and clinical
practice. The investigators previous finding to date suggest that the potential
of FMCG is especially high for evaluation of fetal rhythm disorders. They have
demonstrated several examples of fetal rhythm disturbances that could be
detected by FMCG, but not by ultrasound. Importantly they were also able to
infer the underlying mechanisms. FMCG is also a nearly ideal signal source for
fetal hear rate monitoring, providing a precise signal, free of maternal
interference, which can be detected throughout the last half of pregnancy. The
investigators have shown that it can provide important diagnostic information,
unobtainable by other means, which have the potential to improve the accuracy
of fetal monitoring. The long-term goal of the research is to develop FMCG into
a method that can improve clinical assessment of fetal cardiac function and
fetal well being. The primary technical aims of the project are: 1. To make
FMCG recordings over a wide range of gestational ages using newly acquired
state-of-the-art instrumentation, and to evaluate the quality and success rate
of the measurements; and 2. To apply specialized signal processing technology
which can significantly increase the signal-to-noise ratio of FMCG recordings
and thereby improve the resolution of smaller waveform components, which are
essential for assessment of fetal rhythm. Building upon these advances, the
primary scientific aims are: 3. To perform serial measurements in patients with
a wide range of fetal rhythm abnormalities in order to demonstrate the efficacy
of FMCG for investigating the mechanisms and development of serious fetal
arrhythmia, and to document specific cases in which FMCG can provide an
important diagnostic advantage over ultrasound; and 4. To record the FMCG at
earlier gestational ages than previously possible, and to use these recording
to assess fetal heart rate variability, fetal cardiac waveform parameters, and
other potential indicators of fetal well-being in normal and high risk
pregnancies.
