Radiodiagnosis: A field that revolutionized medicine forever. Radiodiagnosis, also known as diagnostic imaging, is the medical specialty that generates images of the interior of the body using various physical agents. These methods, which are minimally or non-invasive, include X-rays, ultrasound, and magnetic fields.

Why do we need radio diagnosis?

Radio diagnosis method is very helpful in making diagnosis because of its non invasive methods and helpful in making early detection. As it is helpful in making early diagnosis which contributes early treatment plans and monitoring process.

What are the different methods ?

There are many different types of methods available currently for making diagnosis. These are X ray, computed tomography, MRI, ultrasound, fluoroscopy, mammography, nuclear medicine, positron emission tomography, DEXA, interventional radiology.

X - RAY ( Radiography)

It uses X-rays to capture images of various parts of the body, with a particular focus on bones and joints. The equipment emits ionizing radiation to create these images. Typically, the images are reproduced on radiographic films, similar to photographic negatives of the area being examined, though they are increasingly presented in digital format. The signal and resolution are highly accurate, providing excellent image quality.

Magnetic resonance imaging

Magnetic resonance imaging (MRI) uses magnetic waves and radio waves to create detailed images of the body's interior. The body is subjected to an intense magnetic field, producing a resonance that computers interpret to generate these images.

MRI is particularly effective in providing detailed information about joint and soft tissue injuries, such as those affecting ligaments, tendons, bursas, and muscles. Additionally, MRI is useful for evaluating degenerative processes such as osteoarthritis.

Echocardiography

Echocardiography uses ultrasound techniques to produce images of the heart and study its function. With echocardiography, we can determine the shape, size, and strength of the heart, as well as the movement and thickness of its walls and the functioning of its valves.

Computed tomography

A CT scan is a diagnostic imaging exam that uses X-ray technology to produce detailed images of the inside of the body. It can show detailed images of bones, muscles, organs, and blood vessels. CT scans can also be used for fluid or tissue biopsies or as part of preparation for surgery or treatment. They are often performed with and without a contrast agent to enhance the radiologist’s ability to detect abnormalities.

Mammography

A mammogram is an X-ray examination of the breast used to detect and diagnose breast disease in women. This procedure can identify breast cancers, benign tumors, and cysts before they can be felt through palpation.

DXA SCAN

A DXA scan, or bone density test, is a quick and painless method to evaluate your bone health. Unlike a regular X-ray that captures images, a DXA scan measures the strength and mineral content of your bones.

Nuclear medicine

Nuclear medicine is a specialized branch of radiology that utilizes small amounts of radioactive substances, known as radionuclides or radio-tracers, for health research, diagnosis, and treatment of various conditions, including cancer. This field combines various disciplines to create nuclear medicine imaging.

Fluoroscopy

Fluoroscopy is an imaging technique that enables real-time x-ray visualization of a patient with high temporal resolution. It utilizes an x-ray image intensifier connected to a still or video camera. Recently, flat panel detectors, similar to those used in direct digital radiography, have been increasingly replacing image intensifiers.

Conclusion

These above mentioned techniques are widely used in medicine for making the diagnosis and treating the disease at the early stages which is required for treating the disease completely.
