By and large, it has been observed that people conflate radiology with medical imaging. More people are of the opinion that mri radiology is the same as other forms of medical imaging medical diagnostics. However, it must be made clear that radiology is a branch of medicine that utilizes radiant energy to conduct diagnosis and treatment of disease. Hence, the practitioners of radiology are known as radiologists.
On the other hand, the field of medical imaging is a technology that is used by radiologists mostly for diagnostic purposes. Many people have a myth that radiology tests done by the best radiologist in South Delhi involve radiation. But that is not the case for all the tests. For instance, MRI or magnetic resonance imaging, and ultrasound do not use radiation in their medical imaging technologies.
The medical professional who performs the scanning on patients is known as a radiographer. The best radiologist in South Delhi is medical doctors who analyze and study the results of the medical imaging and pass along their findings to the doctors/physicians who ordered the tests. Radiologists are also assigned to check the accuracy and effectiveness of results by monitoring the equipment at the time of the test and by checking the results of further tests once treatment has been administered.
Types of Diagnostic Radiology and Medical Imaging
By and large, the following medical imaging technologies are performed by radiologists:
X-ray – X-rays tests are conducted by using very low-dose radiation and a specialized plate which helps in generating the images of inside the body. This test is advised to obtain images of the bones and joints. Due to the fact that this form of medical imaging technology provides quick results at a relatively low cost, physicians prescribe them to patients. Another form of X-ray known as digital X-ray is also employed for the same purposes.
Computerized tomography (CT) scan – CT scan utilizes the same technology as X-ray to get pictures of the body from every angle. Since the CT scans provide an extremely detailed image in a 3-D pattern, it provides useful information for not just a diagnosis but also for planning and monitoring treatment. A CT scan is primarily used to detect disorders and deformities of bone and muscles, masses, tumors, injuries, and internal bleeding.
Magnetic resonance imaging – MRI tests are performed by using a large, powerful magnet and radiofrequency waves which enables the creation of 3-D images of organs and tissues inside your body. MRI is an extremely beneficial imaging technology that is capable of detecting tumors, injuries, lesions, and infections. The biggest relief for anxiety-stricken patients is that MRI is medical imaging technology. Therefore, it does not use any form of radiation.
Mammography – The test uses very low levels of radiation to detect breast cancer in the early stages. Hence, the physicians who recommend mammography to a woman can get high-quality images using low radiation doses. This test provides images of breast tissues without adding stress to the woman who is supposed to undergo the test.
Nuclear Medicine – It is a type of medical imaging that uses radioactive tracers injected into a vein so that images of the internal organs and structure are produced. Nuclear is effective in diagnosing some cancers, gastrointestinal issues, and endocrine disorders.
Ultrasound – Ultrasound is done in a radiology lab and is primarily useful to get instant, live, real-time pictures onto a computer screen. The radiographer or technician uses a probe and moves it around the area to be scanned in the body to detect any formation on the inside of the body. Ultrasound is very beneficial in looking at the baby in the uterus of pregnant women as it does not use any radiation.
