Non Invasive imaging of the coronary arteries with Computed Tomography is the state of the art technique.
Current CT scanners allow imaging of coronary arteries with a minimal dose of radiation - 0.5 to 1 msev.
In order to achieve imaging contrast agents are introduced and usually premedication is required in order to slow the heart rate down in order to achieve acquisition of the image in one cardiac cycle.
We utilise Cardiac CT to visualise coronary arteries , to assess Heart Valves in selected case as well as a prerequisit for TAVI: percurtaneous replacement of aortic valve.In addition Cardiac CT allows us to assess coronary plaque morphology and detect "vulnarable" coronary plaques.
In 2013- 2014 - 2015 2 years - Cardiac CT Service at the Royal Free Hospital ,which I lead, is at the top of the league in UK with regard to the dose of the radiation delivered based on Audits conducted by British Society of Cardiac computed Tomography.Current Audit details ( 2016) are still pending
