Of 242 adult allogeneic HSCT patients who received voriconazole, 32 patients developed musculoskeletal pain and underwent subsequent serum fluoride measurement. Of those, 31 patients had a plasma fluoride measurement while on voriconazole. Twenty-nine (93.5%) had elevated fluoride concentrations (> 4 Î¼mol/L).
He was 84. The first CT machine took nine days to scan an object. Processing the information by computer then took 21 hours. Despite such formidable obstacles, researchers were undaunted.Hounsfield conceived the idea for a CAT scanner in 1967. By 1972, he had built a machine that produced detailed cross-sectional images of the brain in less than five minutes.
CT scan and MRI introduced. 1972 - 1985. The use of x-rays in medicine was a huge breakthrough at the turn of the century. The problem with x-rays, though, is that they're two-dimensional. Organs of the same density look the same. But British engineer Godfrey Hounsfield came up with an improvement on the 70-year-old technology. It combined x-ray images with a computer. If you took many x-rays of the same area, at slightly different angles, a computer could put the information from the x-rays together to create a cross-sectional image.
