How often can I do abdominal CT?
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.
However, this is not a reason to refuse such a modern and highly informative method of examination of the patient, which is CT.
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.
Contraindications to CT
As for any other instrumental methods of examination, computer tomography of abdominal cavity organs there are few contraindications:
- pregnancy and lactation. If the CT scan of the abdomen shows pregnant for health reasons, the examination can be made only after the preliminary examination and under the supervision of a doctor;
- Allergy to the contrast agent. Hypersensitivity to the radiopaque iodine and other substances is an absolute contraindication to contrast imaging. CT scan without injection of contrast can be done;
- acute renal failure;
- in the presence of artificial pacemakers or other devices implanted in the body of the patient appointment CT scan can be done only after examination and consent of the relevant physician.
How often can I do a CT scan?
The answer is as obvious as the probability of insufficient investigation and the risk of setting the wrong diagnosis – quantum satis (as needed, lat.).
Nota Bene! The most important thing for the doctor – time to make the correct diagnosis and determine the tactics and volume of the required treatment.
Not all medical methods of examination of the abdominal cavity are absolutely harmless or painless, but if on one bowl of scales will be based on the comfort survey and imaginary prospective harmful treatments, and on the other side of his life, the doctor is obliged to choose life. If the installation or diagnosis require a second or even a third CT scan, the doctor should do it as often as necessary.
