CT scanners first began to be installed in 1974. CT scanners have vastly improved patient comfort because a scan can be done quickly. Improvements have led to higher-resolution images, which assist the doctor in making a diagnosis. For example, the CT scan can help doctors to visualize small ...
An essential component of this is adequate patient preparation to ensure study reproducibility and technical quality. Rigorous instructions should be followed regarding patient procedure. In addition, adequate referral information is important so that the correct timing of study and imaging protocol can be...
