The medicinal branch concerned with the use of radiant energy (such as X-rays) or radioactive material in the diagnosis and treatment of disease is called radiology. It is also known as diagnostic imaging.
A wide range of problems can be identified by Diagnostic Radiology (imaging), such as broken bones, heart conditions, blood clots, and gastrointestinal conditions, to name just a few of the problems that can be identified by diagnostic imaging. Many of these tests are unique in that they allow doctors to see inside the body. In addition to identifying problems, doctors can use diagnostic radiology to monitor how your body is responding to current treatment. Diagnostic radiology can also screen for diseases such as breast cancer and colon cancer. It also refers to the field of medicine that employs non-invasive imaging scans to diagnose a patient. The tests and equipment used sometimes involve low doses of radiation to create highly detailed images of an area.
Modern technology gives doctors many options when it comes to diagnosing a patient’s condition. Diagnostic imaging refers to a group of methods that utilize non-invasive techniques to identify and monitor certain diseases.
Examples of diagnostic radiology include:
- Radiography (X-rays)
- Computed Tomography (CT) scans
- Magnetic Resonance Imaging (MRI) Scans – Nuclear Medicine Scans
Why is radiology important?
Radiology is vital to the diagnosis of many diseases, including cancer. Early diagnosis saves lives. Without a diagnosis, there can be no treatment. In radiology, radiologists use imaging technology in the diagnosis and treatment of patients. Radiologists at Yashoda Hospital & Research Centre, Sanjay Nagar, Ghaziabad, use the most advanced diagnostic procedures. Medical imaging is a technology that is used by radiologists specifically for diagnostic purposes. Although the word “radiology” sounds like it involves radiation, that is not always the case – for example, MRI (magnetic resonance imaging) and ultrasound do not use radiation in their medical imaging technologies.
Radiographers are medical professionals who perform scans on patients. Radiologists are medical doctors who interpret the results of medical imaging and pass along their findings to the physicians who ordered the tests. Radiologists can also determine the effectiveness of treatment by monitoring the results of further tests once treatment has been administered.
The most common medical imaging technologies used by radiologists at Yashoda Hospital & Research Centre, Sanjay Nagar, Ghaziabad:
This technology uses low-dose radiation and a specialized plate to produce images of the inside of the body, especially the bones and joints. This is the most frequently used medical imaging technology thanks to its quick results and relatively inexpensive cost. Digital X-rays emit less radiation and are employed for the same purposes.
- Computerized tomography (CT) scan
This utilizes X-ray technology to take pictures of every angle of your body. A CT scan provides 3-D, highly detailed information that is useful not just for diagnosis but also for planning and monitoring treatment. A CT scan can detect bone and muscle disorders, masses, tumours, injuries, and internal bleeding.
- Magnetic resonance imaging
MRI utilizes a large, powerful magnet and radiofrequency waves to create 3-D images of organs and tissues inside your body. An MRI can detect tumours, injuries, lesions, and infections. One attractive benefit of this type of medical imaging technology is that MRI uses no radiation.
This uses low-dose radiation to detect breast cancer in its early stages. Digital mammography requires a much lower radiation dose to produce high-quality images of breast tissue.
- Nuclear medicine
This type of medical imaging uses radioactive tracers injected into a vein in order to produce images of internal organs and structures. Nuclear medicine is used to diagnose some cancers, gastrointestinal issues, and endocrine disorders.
This technology produces live, real-time pictures on a computer screen as the radiographer or technician moves the ultrasound probe around the area of the body in question. Ultrasound, like MRI, contains no radiation, which is why pregnant women use it so often to view their babies in utero.
It uses imaging techniques such as CT scans, MRIs, and ultrasounds, which further help in guiding medical procedures. This technology eliminates the need for surgery and scopes to diagnose and treat certain conditions.
Common uses for interventional radiology include:
- Treating cancers
- Treating blockages in the arteries or veins
- Treating back pain
- Treating liver and kidney problems
Interventional radiologists are highly specialized radiologists who have extra training and experience to safely and accurately perform these procedures. The team of experts at Yashoda Radiology Centre, Sanjay Nagar, Ghaziabad, is led by highly skilled radiologists.
The dedicated team of professional radiologists at Yashoda Hospital & Research Centre, Sanjay Nagar, Ghaziabad, uses the latest and most advanced diagnostic procedures to quickly and accurately diagnose every disease area, making them the leading hospital in Ghaziabad and Delhi NCR.
