Computed tomography is one of the most accurate examination methods which is currently available to the radiologist. Since its discover in 1971, CT has constantly been developed and today achieves an accuracy which enables images to be generated in the highest spatial (layer thicknesses of< 0.4mm) and temporal (examination times of a few seconds) resolution.
The strength of CT lies in its extremely short examination times, which enable all organs in the body (including the lungs and the heart) to be examined without being disturbed by breathing or the heartbeat.
The disadvantage of CT is the exposure to radiation, because the examination is conducted using X-rays. However, the latest technology permits the exposure to radiation to be decreased further despite the ever increasing demands on resolution and speed.
