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.
The authors used computed X-ray tomography (CT) scans to measure calcification in the coronary arteries, aortic arch, and extracranial and intracranial carotid arteries. They also used brain MRI scans to assess cerebral infarcts, microbleeds, and WMLs, which are considered important markers of vascular brain disease.
