X-ray scan: X-rays formates on the film through examination parts of human body. Some people think that the cough and fever shouldn’t scan because of much radiation, but the X-ray perspective is more safe, But the concept is wrong.

X-ray scan is the first choice of chest examination.

But the radiation of X-ray perspective is much more than X-ray scan. According to related experts, the x-ray dosage is 20 ~ 30 times of ordinary scan which adult accepts chest examination. But the children don’t cooperate with because of crying; The doctors usually extend the time of perspective to observe lesions and accepted x-rays dosage is more than theory. Therefore, x-rays scan is the best choice of chest check and perspective is a beneficial supplement of scan.

Most of hospitals of our country has cancelled perspective

On the one hand, definition of perspective image is far worse than scan and is easy to miss tiny lesions and subtle structure; On the other hand, perspective cann’t record the image of lesions and is bad for reviewing and contrasting. In developed countries of America and Japan, they have eliminated perspective; A few countries have decreased the utilization rate that use this method. At present, In some parts of China large hospitals have eliminated perspective and so advised that please try to choose scan and not perspective.
