What is medical imaging?

Medical imaging is a discipline in the field of medical field, which includes the use of technology to purchase the interior of the human body. These images are used in diagnostics, such as teaching tools and in routine health care for different conditions. Medical imaging is sometimes referred to as diagnostic imaging, as it is often used to help doctors to diagnose, and there are a number of different types of technologies used in medical imaging.

The aim of medical imaging is to provide a picture of the inner state of the body in a way that is as non -invasive as possible. Imaging studies can be used to identify unusual things inside the body, such as broken bones, tumors, blood vessel leakage, etc. One of the most famous types of diagnostic imaging is the X -ray that uses radiation to take a static image of a particular area of ​​the body.

In addition to X -rays, relatedIt is also possible to use ultrasound to look inside the body by jumping sound waves from the body cavity to create a picture and using magnetic resonance imaging to agitate cells to get a picture of the body. Medical imaging can also produce dynamic images such as brain activity scan or heart images that can be used to find diagnostic problems that would not appear in a static image. More invasive techniques include inserting the camera into the body to make a video of an area of ​​interest.

Some imaging studies simply require image capture, while others include the introduction of contrasting material to the body. The contrasting materials are swallowed or injected and are designed to be highly visible in the picture, allowing doctors to monitor their progress by the body. For example, barium swallowing can be used in X -ray X -ray to find ulcers and perforate while radioactive contrasts MOhou be injected to seek signs of thyroid cancer.

New technology for medical imaging is developing all the time, including machines that are less invasive and technology, reducing the need for radioactive materials and other harmful substances in medical imaging. The latest technology tends to be available in research hospitals and urban medical centers, where a large budget can comply with the purchase of expensive new equipment, while rural facilities tend to have older and outdated equipment that is sometimes less effective in diagnostics.

The

process involved in obtaining images varies depending on the technology used and the body area that is displayed. When a physician orders a patient's medical imaging study, he can go through the procedure or ask the nurse to provide information to the patient to know what to expect.
