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.
He suggested radiosurgery for the treatment of deep-seated brain tumors. The first device for routine clinical use based on this idea was the prototype Gamma Knife constructed in 1967-68. Dr. Leksell treated the first acoustic neuroma with the technique in June 1969 at Karolinska Hospital in Stockholm, Sweden.
