With the progress of science and technology and the improvement of people's living standards, people pay more and more attention to physical health, slight discomfort, will go to the hospital for examination, conventional ultrasound as the basis of screening methods, more and more widely used.
However, in our daily examination of "Superman", some people have negative test results, and patients complain about it, "Oh, and nothing, so why is it still uncomfortable?" "This money has been spent in vain," some people said they could not understand.

But why is this happening?
First of all, conventional ultrasound as a basic examination method is not a panacea, many diseases are not the specialty of ultrasound, can not be detected, such as the patient complaining of right upper quadrant pain, the doctor will prescribe a "hepatobiliary pancreas spleen" ultrasound examination, except for whether there are problems with the gallbladder or liver, such as tumors, stones, inflammation, etc., ultrasound found that the liver and gallbladder are "good", it may be colon liver curvature, duodenum, analgia or chest cavity and rib problems, these are not the expertise of ultrasound examination, ultrasound for hollow organs, The bones and gaseous tissues were powerless, and of course the test results were negative.
Secondly, although the level of science and technology is improving, ultrasonic instruments are becoming more and more sophisticated, but the resolution of ultrasound is limited due to physical imaging, the accuracy of the examination is also limited, and then there is ultrasound due to the interference of the patient's body fat or abdominal gas, the examination is also limited, for example, less than 3mm of ureteral stones, in the patient is more obese or abdominal flatulence, it can not be detected, but ultrasound can find some indirect signs, such as whether there is hydronephrosis, although ultrasound did not find positive stones, However, according to the results of the urine test, clinicians can also diagnose urinary tract stones, so ultrasound is also indispensable for clinicians.
Ultrasound is not "useless", or "spend money in vain", ultrasound can exclude many structural abnormalities, such as gallstones are the specialty of ultrasound, CT and MRI can not be compared, there is ultrasound in gynecology, obstetrics has a wide range of applications, musculoskeletal ultrasound is also more and more accepted by clinicians, and the application is increasing. A negative result on ultrasonography indicates that the problem is not large, or in the early stages of the disease, which can be combined with other tests, if a disease is highly suspected, CT or MRI can be performed, ultrasound does not find a problem, nor can it mean that ultrasound is "white".

Any kind of examination of modern medicine has its limitations, not a panacea, science and technology are constantly advancing, artificial intelligence in the medical field is more and more widely used, I believe that in the near future, ultrasound can also break through the existing limitations, for the improvement of people's health level to contribute to a force.
