Methods of intravascular impedance plethysmography when used in the clinic during catheterization of heart cavities can reliably diagnose coarctation of the aorta and incompetence of its valves. The intravascular impedance plethysmography is a substantial supplement to the arsenal of methods of examination in the angiographic unit.

Association between serum albumin and body water using a bioelectrical impedance analyzer: a case report of longitudinal variation in a child with initial idiopathic nephrotic syndrome.

Article Synopsis
- - Bioelectrical impedance analysis (BIA) is a noninvasive method for assessing body composition and fluid status, particularly useful in pediatric patients with nephrotic syndrome, where albumin leaks into urine disrupt blood volume.
- - A case study of a 6-year-old with nephrotic syndrome showed a significant negative correlation between serum albumin levels and the extracellular water/total body water ratio (r=-0.72, P<0.04) during treatment with prednisolone.
- - The findings suggest that BIA could reliably predict serum albumin levels noninvasively, potentially minimizing the need for frequent blood tests in children, though further research is necessary for validation.
Invasive electrochemical impedance spectroscopy with phase delay for experimental atherosclerosis phenotyping.

Distinguishing quiescent from rupture-prone atherosclerotic lesions has significant translational and clinical implications. Electrochemical impedance spectroscopy (EIS) characterizes biological tissues by assessing impedance and phase delay responses to alternating current at multiple frequencies. We evaluated invasive 6-point stretchable EIS sensors over a spectrum of experimental atherosclerosis and compared results with intravascular ultrasound (IVUS), molecular positron emission tomography (PET) imaging, and histology.

Blood vessel detection is an essential method in a non-invasive circulatory monitoring system. However, only using camera-based image processing for finding a vein has many limitations due to the complexity of underneath tissue. Impedance tomography and spectroscopy can collect electrical characteristics map of the biological tissue precisely.

Determining body contents such as body water volume and body cell mass have significant uses in health and disease. Accumulation of extracellular water is particularly difficult to monitor using classical methods. Bioelectrical impedance analysis (BIA) is a simple, rapid, and noninvasive method, based on the principle that the flow of altering electrical current through a particular tissue differs depending on the content of water and electrolytes.
