Re: Sizzling/Fizzing in throat. I don't know what it is but I also have that same thing. It happens to me when I'm lying, sitting or standing and even when I haven't eaten anything. Good luck hope you find out whats going on.
The Evolution of CT Scan Clinical Trials. Submitted by Bioclinica on July 22, 2011 - 11:46am. On October 1, 1971, CT scanning was first introduced by Godfrey Hounsfield into medical practice with a successful scan on a patient at the Atkinson Morley Hospital in Wimbledon, London using a prototype scanner.
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.
