Noninvasive imaging of tumor vascularization in animal models provides an important tool for studying the biology of tumor angiogenesis as well as monitoring the effects of antiangiogenic therapies. Through the use of in vivo multispectral fluorescent imaging, we have discovered a distinct spectral signature associated with blood vessels present in fluorescent tumors in mice. This unique spectr...
This pilot study examines noninvasive MR monitoring of tissue-engineered vascular grafts (TEVGs) in vivo using cells labeled with iron oxide nanoparticles. Human aortic smooth muscle cells (hASMCs) were labeled with ultrasmall superparamagnetic iron oxide (USPIO) nanoparticles. The labeled hASMCs, along with human aortic endothelial cells, were incorporated into eight TEVGs and were then surgic...
BACKGROUND Noninvasive capnography is not routinely available on portable transport patient monitors but can be useful in respiratory monitoring of spontaneously breathing patients during transport, especially when sedation is administered. We describe an assembled setup of face mask capnography. The purpose of this study was to assess the feasibility and performance of an assembled face mask c...
Clinical monitoring of shock mainly depends on blood-oxygen-indices obtained from invasive blood sample tests. The central internal jugular central vein oxygenation level (ScvO2) has been considered as a gold standard indicator for shock prediction. We developed a noninvasive spatially-resolved near-infrared spectroscopy (SR-NIRS) to measure tissue blood oxygen saturation (StO2) surrounding the...
nique and the patient’s enlarged heart geometry.5,6 In addition, echocardiography is not a monitoring device. Right heart catheterization (RHC) is a direct measurement of hemodynamic parameters7 and is a reliable tool for evaluating hemodynamic changes in PH patients. However, the frequent use of RHC is also limited by its invasiveness, infection risk, and expense.8 Therefore, a noninvasive tec...
