Nowadays, there is no method to quantitatively characterize the material composition of acute ischemic stroke thrombi prior intervention, but dual-energy CT (DE-CT) offers imaging-based multimaterial decomposition. We retrospectively investigated ex vivo using DE-CT with histological analysis as a reference.
Abstract The separation of mixtures substances into their individual components plays an important role in many areas science. In medical imaging, one method is the established analysis using dual-energy computed tomography. However, when analyzing consisting more than three basis materials, a physical limit reached that no longer allows this standard analysis. addition, X-ray attenuation coefficients chemically complicated materials may not be known and also cannot determined by other or...
Abstract Background Dark-field radiography imaging exploits the wave character of x-rays to measure small-angle scattering on material interfaces, providing structural information with low radiation exposure. We explored potential dark-field bone microstructure improve assessment strength in osteoporosis. Methods prospectively examined 14 osteoporotic/osteopenic and 21 non-osteoporotic/osteopenic human cadaveric vertebrae (L2–L4) a clinical system, micro-computed tomography (CT), spectral...
