Radiological methods of a research are applied in medicine more than hundred years, and thanks to them millions of lives were saved. In many cases without X-ray it is impossible to make exact idea of a condition of bodies and fabrics, it is correct to make the diagnosis. Nevertheless, many myths about researches such continue to exist. Let's consider the most widespread of them.
X-ray, passing through a body of the person, can cause:
The probability of emergence of any negative processes directly depends on the exposure dose received by the patient. For the majority of diagnostic radiological procedures these doses are extremely small. For example, at fluorographic inspection which is recommended to be undergone annually the person receives on average about 500 μSv (microsievert), and when carrying out a X-ray analysis of one tooth – only about 30 μSv. In view of that the dose in 50000 μSv received within a year, about any danger of death of radiological procedures out of the question officially is considered unhealthy.
As it is not strange, antithetic is not absolutely right too. The heaviest from the point of view of an exposure dose are procedures of a computer tomography of abdominal organs (everyone – about 20000 μSv). In principle, several such researches made during the short period bear potential risk for health.
For this reason doctors, appointing radiological diagnosis, have to be guided by data of other researches and direct need, but not desire of patients.
Statistically, the probability of malignant regeneration of cells at the patients inspected by method of a computer tomography makes about 0,1% (one case on 1000 researches). For the most widespread procedures (such as chest X-ray) this risk makes 1 case on one million patients who passed a research.
Radiological diagnostic methods have no actually medical contraindications. At purpose of inspection the doctor has to estimate need of holding a procedure and correlate its potential danger to a condition of the patient. The special attention is required by carrying out X-ray analyses to chest babies and future mothers. If there is an opportunity to use the method which is not connected with radiation (for example, ultrasonography), the doctor will surely give it preference.
According to most of physicians, no rehabilitation after radiological diagnosis is required. Influence to which the organism is exposed during the procedure is short-term, and the received exposure dose – minimum. Patients who nevertheless are afraid of negative effects should drink more liquid after inspection: it will help an organism to stabilize quickly a metabolism and to remove decomposition products.
Radiological diagnosis is widely applied at fight against internal diseases, various injuries, in oncological and ftiziatrichesky practice. As a rule, procedures are absolutely necessary: without them neither diagnosis, nor assessment of efficiency of treatment are impossible. At the same time similar methods are almost safe, are not traumatic and, in most cases, are comfortable for the patient.
