X-ray examination is a common examination in hospitals, widely used in hospitals. It has the advantages of low cost, convenient examination, and low radiation dose, which greatly facilitates patients' visits and lays the foundation for their subsequent treatment. However, in the current development, there are still many people who are not familiar with X-ray examinations in radiology. The following is a popular science presentation to help more people understand X-ray examinations.
1. Advantages and disadvantages of X-ray examination
The operation of X-ray examination is simple and does not require high equipment requirements. During the examination, it can rotate the patient in multiple directions, intuitively observe the patient's activity, and the cost of this examination is relatively low. The corresponding results can be obtained in a timely manner after the examination is completed. Its radiation effect is relatively low and relatively safe. The disadvantage is that fluoroscopy examination affects contrast and lacks idealization, making it difficult to observe small lesions and thick areas.
2. Application scope of X-ray examination
This examination method has a good effect on the chest and has been widely used in chest fluoroscopy. It can also be applied in emergency abdominal examination to timely observe stones, metal foreign bodies, gastrointestinal imaging, etc. It can also be used in bone fracture review, foreign body removal, interventional therapy, and intubation treatment, which can achieve good therapeutic effects.
3. Radiology X-ray examination does not emit radiation to the surrounding environment. X-ray examination uses X-rays to penetrate the human body, and X-ray machines emit ionizing radiation. Ionizing radiation beyond the range of the human body can have an impact on the human body, but this type of radiation is strictly controlled within the radiology department. And the radiation will not emit when the inspection instrument is not turned on, and the walls around the inspection room are thickened and contain barium sulfate, with good protection conditions, and will not radiate to the human body.
Why does X-ray examination require undressing?
Depending on the examination site and method, there are different image requirements. Due to the metal buckles on the underwear, jeans, and other clothing of the inspected personnel, it is inevitable that they will affect the imaging. Therefore, radiologists will require the removal of foreign objects during the examination to reduce the presence of artifacts and better ensure the diagnosis of the disease. So, patients need to actively cooperate with doctors and follow their instructions during examinations.
5. Can breastfeeding women receive X-ray examinations? Breastfeeding women can occasionally undergo low-dose regular X-ray examinations, which will not have any impact on the human body. This is because X-rays pass through the human body for a very short time and do not stay in the body, so they will not damage the nutrition of milk or affect the mother's breastfeeding.
6. Precautions for examination
Firstly, during the examination, regardless of the part being examined, it is necessary to remove the metal hair patches, metal necklaces, gold rings, etc. carried with you and cooperate with the doctor's instructions to make the results more accurate.
Secondly, when examining the abdomen, it is necessary to fasting for at least 8 hours. Since X-ray examination itself is an overlapping image, once there is content in the gastrointestinal tract, it will directly affect the quality of the imaging and cause interference.
Thirdly, during the examination, it is necessary to follow the instructions of medical personnel, maintain a static state, and reduce the effect of image artifacts to assist in the diagnosis of the disease, so that doctors can prescribe targeted medicine for the actual condition.
Fourthly, during the examination, it is necessary to understand one's own symptoms in advance and seek the corresponding department doctor for consultation, and select the X-ray examination site under the guidance of the doctor.
