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 scans were developed in 1972 and used before MRIs. CT, or CAT as they're pronounced, stands for computerized axial tomography.. In a CT scan, the patient lies on a table that slides into a scanning machine. Inside, an x-ray beam rotates around the body while detectors measure how much of the x-rays pass through the tissues and organs, indicating density.
