Radiology is a branch of medicine that utilizes imaging technology to diagnose and treat diseases.
Medical imagingis the term used to describe the technologies used to observe the human body for the purpose of diagnosing, monitoring, or treating medical conditions. Radiology is the field of medicine that harnesses the power of diagnostic imaging to provide relevant information to other medical professionals. Medical imaging is an essential component in a variety of medical settings and at all major levels of health care. The use of diagnostic imaging services is essential for confirming, evaluating and documenting the course of many diseases and the response to treatment.
X-rays, which use electromagnetic waves to generate images of bones, blood vessels and soft tissues inside the body, are the oldest form of diagnostic imaging and have been around for more than 100 years. Diagnostic ultrasound (US) systems use high-frequency sound waves to produce images of the body's internal organs and soft tissues. This type of imaging, a more advanced version of X-rays, is especially effective for patients who suffer trauma or internal injuries. Other types of non-radioactive imaging include magnetic resonance imaging (MRI) and ultrasound (US). The type of imaging the doctor uses depends on the symptoms and the part of the body being examined.
Unfortunately, many low- and middle-income countries cannot afford diagnostic imaging equipment, and there is often a shortage of health workers trained to use such equipment. WHO collaborates with partners and manufacturers to develop technical solutions to improve diagnostic imaging services in remote locations. Medical imaging encompasses technologies such as ultrasound, x-rays, mammography, computed tomography (CT) and nuclear medicine. The World Health Organization (WHO) recognizes that ultrasound is an important medical imaging technology. Considered by the New England Journal of Medicine as one of the most important medical advances of the last thousand years, medical imaging technology has revolutionized health care by allowing for earlier diagnosis of diseases, better outcomes for patients and reducing the need for invasive and improper exploratory procedures.
This imaging technique has provided us with an exact relationship between magnetic resonance signals that map neural activity. Some types of medical imaging work without ionizing radiation; for example, magnetic resonance imaging (MRI), angiography, and ultrasound have important applications in diagnosing diseases. It would be crucial to design medical imaging modalities that can recognize a “fingerprint” that can be attributed to a specific pathological condition. In addition, the images used in nuclear medicine and angiography can be attributed to several techniques for visualizing biological processes. Modern diagnostic imaging offers a wide spectrum of modalities and techniques that allow us to study the function and morphology of the human body.
