While the levels used in a single scan are generally safe, cumulative exposure poses a theoretical risk, particularly for children and younger patients. The first clinical CT scan was performed in 1971 on a patient suspected of having a brain tumor.

Subsequent advancements led to whole-body scanners, faster rotation times, and the integration of multi-detector row technology, drastically reducing scan times and improving image clarity. Modern protocols include screening patients for allergies and kidney function, as contrast can temporarily affect renal function.
During the procedure, the patient lies on a motorized table that slides through a large circular opening known as the gantry. Furthermore, it plays a crucial role in guiding surgical procedures and biopsies, providing real-time imaging that allows physicians to navigate precisely to the target area with minimal invasion.

For abdominal or pelvic scans, patients are often instructed not to eat or drink for several hours beforehand. As the table moves, the X-ray tube and detectors rotate around the body, emitting thin beams of radiation that pass through different tissues at varying intensities.
