Computed tomography is one of the most informative and valuable methods of diagnostic examination of the patient in all fields of medicine.

Physical basis of computed tomography

In order to assess how dangerous or not a CT scan and how often you can do CT scan of abdomen it is necessary to understand the physical basis and technology. Abdominal CT based on layer-by-layer radiography of the test body, or rather, all organs located in the projection study. Images are produced simultaneously from several points located circularly around the patient’s body, further received data are processed, are combined through special computer programs and the radiologist gets the final result in the form of x-ray picture of the slice of the patient’s body.

How dangerous and harmful to any x-ray examination, as well equally dangerous and computed tomography of the abdomen. It should be borne in mind that the production CT is done simultaneously from a series of x-rays, an adverse effect on the health of the patient which is arithmetically superimposed on each other.

Nota Bene! The danger of false diagnosis, underestimation or a misinterpretation of the clinical, laboratory and instrumental data obtained only at the expense of obsolete methods of examination, a hundred times outweighs the potential harm of imaging.

On the one hand, it is impossible to challenge these medical studies confirming the relative harm that would result from numerous x-ray exposures. On the other hand, statistically not aware of a large number of terminally ill patients who died merely because they were made unnecessary x-rays. The number of people in the world who have died as a result of late or erroneous diagnosis is not measured just in the hundreds of thousands, and millions.
