Diffraction-enhanced X-ray imaging of articular cartilage

Diffraction Enhanced X-ray Imaging of the Articular Cartilage of Experimental Animals

Introduction: The clinical techniques utilized in the assessment of the health status of articular cartilage of synovial joints include x-ray radiography, magnetic resonance imaging and ultrasound (1). Conventional radiography provides the highest spatial resolution (2) and is the most commonly used technique. However, because cartilage is not visible with standard x-rays, the radiographic eval...

Diffraction enhanced x-ray imaging.

Diffraction enhanced imaging is a new x-ray radiographic imaging modality using monochromatic x-rays from a synchrotron which produces images of thick absorbing objects that are almost completely free of scatter. They show dramatically improved contrast over standard imaging applied to the same phantom. The contrast is based not only on attenuation but also the refraction and diffraction proper...

Diffraction Enhanced X-ray Imaging of Biological Tissues

The purpose of this study was to explore the potential of refraction contrast X-ray imaging of biological systems. Images of a UK mammography test phantom, mouse lungs, heart, liver and legs, together with a human finger, were recorded using the SYRMEP beamline. The technique used has become to be known as ‘Diffraction Enhanced Imaging’ (DEI), which utilises a silicon crystal placed between the...

Yes, you can see cartilage with X-rays; diffraction enhanced X-ray imaging for soft and hard tissues.

Human articular cartilage and fibrocartilage: a study with high-angle x-ray diffraction.

High-angle x-ray diffraction was applied to the study of four meniscal fibrocartilages and 11 articular cartilages from patients suffering from various articular disorders. In eight samples microcrystals were seen, apatite most frequently, CaHPO4 in two instances, calcium pyrophosphate dihydrate (CPPD) in one. These results confirm the association of various crystals in a single joint, and favo...
