Medical x ray try to do less capital University of medical sciences Director Yi on diagnosis and treatment of lung cancer x ray to do less "/>regardless of the entry, entry medical examination, are also units in each of the general medical examination, have a" chest x ray "which is abbreviated as" chest ". Medical experts pointed out that the x-ray as a means of checking of a backward, both see the lesion, and easily absorbed large amounts of radiation, should be replaced with x-rays. It is learnt that developed and largely eliminated off the perspective of the Hospital of Beijing in China, but in medical institutions in other cities, they are also served in the large. Disadvantages:perspective easily missed, have white shines as aperspective found lung cancer could not read, be sure to check from the front and side chest. Perspective on the positive rate of lung cancer and other tumors found are very low, often perspective 1000~2000 can be found 1~2 patients. Perspective of discovery weak there are a number of factors, such as instrument operator only one colleague in judgment when not even discuss without impeded check for accuracy. Disadvantages of perspective also includes review process did not leave a film or video recordings, not patients in comparison with before and after the check, inspection results or retained as evidence, between the hospital does not recognize each other's results. By contrast, digital x-ray (DR) check not only look better, you can also leave electronic images or flushing out of the film, patients have needed can also carve CD, or directly copy away from the hospital, saved on your PC. Disadvantage of the second:could not read, the patient suffered radiation for a long timeperspective and film, in which more people suffered radiation? Due to the different perspective on the quality of machine and x-ray radiation vary greatly, and the perspective of the length of time is not consistent, so it is difficult to generalize how much radiation is more perspective than film. According to the imported machine exposed to radiation in perspective 5~10 times larger than the average x ray machine, which DR are greater than the amount of radiation exposure. In perspective during the inspection, the longer, for inspection by the greater the amount of radiation. Operation doctors sometimes lack of experience, judgment of images are not clear; or are home-made machines, poor image quality, "Snowflake", operation doctors demand slows down operations action if suspicious lesions, even repeating watch it over sth These cases, the operation doctors has been stepped on foot switch, up until you see, so that actual amount of radiation is very large. Iatrogenic harm caused by radiation will check on the human body, causing gene mutation, increase the risk of cancer. According to the calculation of the medical profession, healthy women accept a perspective, each breast at least 1000 millirem radiation absorption, this means that the probability of breast cancer would increase 1%. Perspective more dangerous to children, to the eye as an example, as a child, by radiation, is likely to have radiation cataract in the future. Reminder:perspective once a year there is no needto take a medical examination tables indecisive person advice: perspectives can not do not do. Young people physically healthier, trying not to do, current physical examination once a year perspective is certainly not necessary. High risk population of pulmonary tuberculosis, family history, clinical symptoms occur, including tuberculosis and tuberculosis patients around contacts or just clean air to foul atmosphere of big cities in the country, consider checking; carcinoma high-risk population, taking into account tumor doubling takes time, General 1-2 check again. Of such perspectives can an x ray to shoot.
