Pathological studies on calcification of the intervertebral discs. 1982

C W Chou

Calcified deposits in the intervertebral discs of 35 cadavers microradiographically appeared as linear of flake-like densities composed of calcium pyrophosphate dihydrate (CPPD) crystals and as multiple punctates possibly composed of dicalcium phosphate dihydrate (DCPD) crystals. Calcium deposits were found in 57% of the cadavers by microradiography and 63% by light microscopy, without known metabolic or familial history related to articular chondrocalcinosis. By scanning electron microscopy, CPPD crystals were mainly rod-like, rectangular and cuboid and were about 4 to 10 mu in length while DCPD crystals were prismatic and about 20 to 60 microns in length.

D008852	Microradiography	Production of a radiographic image of a small or very thin object on fine-grained photographic film under conditions which permit subsequent microscopic examination or enlargement of the radiograph at linear magnifications of up to several hundred and with a resolution approaching the resolving power of the photographic emulsion (about 1000 lines per millimeter).	Microradiographies
D008855	Microscopy, Electron, Scanning	Microscopy in which the object is examined directly by an electron beam scanning the specimen point-by-point. The image is constructed by detecting the products of specimen interactions that are projected above the plane of the sample, such as backscattered electrons. Although SCANNING TRANSMISSION ELECTRON MICROSCOPY also scans the specimen point by point with the electron beam, the image is constructed by detecting the electrons, or their interaction products that are transmitted through the sample plane, so that is a form of TRANSMISSION ELECTRON MICROSCOPY.

D002131	Calcium Pyrophosphate	An inorganic pyrophosphate which affects calcium metabolism in mammals.
