What is radiography… Radiology is a medical specialty that employs the use of imaging to both diagnose and treat disease visualized within the human body. Radiologists use an array of imaging technologies. It may use x-ray machines or other such radiation devices. Or It also uses techniques that do not involve radiation, such as MRI and ultrasound.
Slide 3-

types… Radiology can refer to two sub-fields, diagnostic radiology and therapeutic radiology. Diagnostic radiology is concerned with the use of various imaging modalities to aid in the diagnosis of disease. Therapeutic radiology—or, as it is now called, radiation oncology uses radiation to treat diseases such as cancer using a form of treatment called radiation therapy.

 Commonly used techniques for diagnostic radiology includes Computed tomography (CT) Magnetic resonance imaging (MRI) Ultrasound X-rays Nuclear imaging techniques

CT- SCAN
Slide 6-

CT scan Computed tomography (CT) is a type of imaging. It uses special x-ray equipment to make cross- sectional pictures of your body. Doctors use CT scans to look for Broken bones Cancers Blood clots Signs of heart disease Internal bleeding

X-RAYS
Slide 8-

X-rays X-rays are basically electromagnetic radiations which are used to create images of inside your body. The images show the parts of your body in different shades of black and white due to different level of absorption of x-rays by different tissues Calcium in bones absorbs x-rays the most, so bones look white. Fat and other soft tissues absorb less, and look gray. Air absorbs the least, so lungs look black.

The most familiar use of x-rays is checking for broken bones However, x-rays are also used in other ways. For example, chest x-rays can spot pneumonia. Mammograms use x-rays to look for breast cancer.

MRI
Slide 13-

MRI scans Magnetic resonance imaging (MRI) uses a large magnet and radio waves to look at organs and structures inside your body. Health care professionals use MRI scans to diagnose a variety of conditions, from torn ligaments to tumors. MRIs are very useful for examining the brain and spinal cord.

Nuclear medicine Nuclear scans use radioactive substances to see structures and functions inside your body. They use a special camera that detects radioactivity. Nuclear scans can help doctors diagnose many conditions, including cancers, injuries, and infections. They can also show how organs like your heart and lungs are working. The heart, lungs, thyroid, liver, gallbladder, and bones are commonly evaluated for particular conditions using these techniques.

Ultrasound Ultrasound is a type of imaging. It uses high-frequency sound waves to look at organs and structures inside the body. Health care professionals use it to view the heart, blood vessels, kidneys, liver, and other organs. During pregnancy, doctors use ultrasound to view the fetus. Unlike x-rays, ultrasound does not expose you to radiation.
