Two main functional imaging approaches have been used to measure regional lung perfusion using Electrical Impedance Tomography (EIT): venous injection of a hypertonic saline contrast agent and imaging of its passage through the heart and lungs, and digital filtering of heart-frequency impedance changes over sequences of EIT images. This paper systematically compares filtering-based perfusion estimates and bolus injection methods to determine to which degree they are related.

The aims of this study were to investigate the ability of contrast-enhanced dual-energy computed tomography (DECT) for assessing regional perfusion in a model of acute lung injury, using dynamic first...
Fluid bolus therapy for the treatment of sepsis may lead to the accumulation of extravascular lung water (EVLW) and result in respiratory dysfunction. We aimed to assess changes in EVLW using lung ult...
Air pollution becomes more and more serious with the rapid development of the society, and the haze caused by particulate matters (PMs) has become a global problem. Thus seeking an effective technolog...
We reviewed our combined clinical outcome in patients who underwent lung transplantation after ex vivo lung perfusion (EVLP) and compared it to the contemporary control group.
In this study, we aimed to compare the split-bolus and single-bolus computerised tomography (CT) urography and determine if this offers a reduction in radiation dose without compromising image quality...
The aim of this randomized trial is to compare the efficacy of high dose tirofiban administered as either an intracoronary bolus alone or as an intravenous bolus followed by a maintenance ...
To compare the effect on blood retinal barrier disruption 3 and 12 months after implantation of either a blue light filtering intraocular lens(blue-filtering IOL) or an ultraviolet light f...
This pilot clinical trial studies computed tomography (CT) perfusion imaging in predicting treatment response in patients with non-small cell lung cancer or tumors that have spread from th...
To determine whether postoperative subconjunctival injections of 5-fluorouracil (5-FU) increase the success rate of filtering surgery in patients at high risk for failure after standard gl...
Ex vivo lung perfusion (EVLP) is an established strategy to evaluate and optimize high-risk donor lungs that would otherwise be rejected for transplantation mainly due to the presence of e...
Comparison of various psychological, sociological, or cultural factors in order to assess the similarities or diversities occurring in two or more different cultures or societies.
An analytical transmission electron microscopy method using an electron microscope fitted with an energy filtering lens. The method is based on the principle that some of the ELECTRONS passing through the specimen will lose energy when they ionize inner shell electrons of the atoms in the specimen. The amount of energy loss is dependent upon the element. Analysis of the energy loss spectrum (ELECTRON ENERGY-LOSS SPECTROSCOPY) reveals the elemental composition of a specimen. It is used analytically and quantitatively to determine which, how much of, and where specific ELEMENTS are in a sample. For example, it is used for elemental mapping of PHOSPHORUS to trace the strands of NUCLEIC ACIDS in nucleoprotein complexes.
