Radiography is the science of using radiation to image tissues, organs, bones, and blood vessels in the body. This method uses high-energy rays that are similar to sound waves and microwaves, but can pass through the body and display images of internal structures. This diagnostic method involves a wide variety of different types of imaging. It is used to diagnose injuries, diseases and fractures. In the following, you can get acquainted with the types of radiography and the uses and dangers of each. Stay with us.
What is radiography?
Medical radiography is a broad term that includes a variety of X-ray images of internal organs. X-ray or radiography is a way to create and record an X-ray design to create a still image that remains after the x-ray is taken.
This imaging technique helps diagnose and treat patients by capturing images of patients’ internal structures. Existing images can show the presence or absence of disease, foreign objects, and damaged or abnormal structure.
During a radiograph, an x-ray is passed through the body. Some of this radiation is absorbed or diffused by the internal organs of the body and the rest of the X-rays are transmitted to the sensor. Recording the remaining pattern of the beam can be digital or on film.
What are the uses of radiography?
X-ray radiography: This method is used to diagnose bone fractures, some abnormal tumors and masses, pneumonia, some injuries, calcium deposition, the presence of foreign bodies, and dental imaging.
Mammography: This type of radiograph is used to diagnose breast cancer. Tumors are lumps with regular or irregular shapes that appear more clearly in the background of the radiographic image. Mammograms can also show very small particles of calcium. Although these calcium deposits are usually benign, they can be a sign of certain types of cancer.
CT Scan: This method combines X-ray technology with computer processing to provide images of various body sections that ultimately form a three-dimensional shape. CT images are more detailed than regular radiographs and allow the doctor to examine the internal structures of the body from different angles.
Fluoroscopy: Using X-rays and a fluorescent screen, you can see vivid images of movements inside the body, such as the path of the contrast material injected or eaten. Fluoroscopy of the beating heart can also show the flow of blood to the heart muscle and other organs and arteries.
Radiation therapy for cancer treatment: X-rays and other high-energy rays can be effective in destroying tumors and cancer cells by destroying DNA. The intensity of radiation for cancer treatment is much higher than the radiation needed for diagnostic imaging. In this method, an in vitro device or an in vivo radioactive substance can be used.
Reasons for doing radiography
Radiography may be needed if any of the following occur:
- Bone fracture;
- Blocked artery or vein;
- Existence of a foreign body in the body;
- The possibility of a tumor or cancer;
- Dental treatments;
- Muscle rupture.
If your doctor prescribes a radiograph, you will need to see a radiologist and a radiologist.
Preparing for radiography
No special preparation is required for simple X-ray imaging. It is only important that you inform your doctor and radiologist if you are likely to become pregnant. In this way, the imaging may be done in a different way or a completely different experiment.
It is usually necessary to wear hospital gowns, as some garments can interfere with the sharpness of the images. You may also need to remove some items such as watches, necklaces and clothes with iron parts such as zippers.
If the radiograph is taken to check the condition of the injury or the progression of the disease, it is necessary for the client to show all his previous X-ray images to the radiologist. The specialist writes a report for the doctor to compare the new image with the images from previous tests and see the changes.
How long does this test take?
This shooting usually takes less than 15 minutes. Of course, the total time of the test depends on the number of organs that need to be imaged. In most cases, the site is examined from several different angles to provide sufficient information for a medical diagnosis. Therefore, it may be necessary for the client to change status.
Chest radiographs take less than a minute for a healthy co-worker, but it may take more than 45 minutes to photograph a distressed patient who needs radiographs of the entire spine, pelvis, both shoulders and legs.
Used properly, the benefits of X-rays far outweigh the risks. This test can be effective in diagnosing deadly diseases such as blockage of blood vessels, bone cancer and infection.
However, X-rays produce ionizing radiation that can damage living tissues. This risk increases with the number of tests you do throughout your life. Of course, the risk of cancer due to these rays is low.
In general, if imaging of the abdomen and pelvis is necessary, the doctor will use methods that do not require the use of radiation, such as MRI or ultrasound. However, X-rays can be used if none of these methods work or there is a time limit.
Children are vulnerable to ionizing radiation and are at higher risk for cancer. Parents can ask the radiologist or doctor to adjust the imaging tool for children to use.
This method is quick and easy, so it is widely used for emergency diagnoses and treatments. Radiography can be used to diagnose a variety of diseases, including:
- Heart failure;
- Bone infections;
- Lung failure.
Instruments for this type of imaging are available in many hospitals and imaging clinics and are available to physicians and patients. By knowing the types of radiographs, their applications, and their dangers, you can be better prepared for your next imaging and perform this test more easily.
