The Different Types of Radiology Procedures

radiology

Radiology is a branch of medicine that uses medical imaging techniques to diagnose and treat diseases. Medical imaging includes X-rays, computed tomography (CT), magnetic resonance imaging (MRI), and ultrasound. Associate professor of Radiology at the Harvard Medical School, Dr Johan Blickman explains the different types of procedures involved.

There are many different types of radiology procedures:

1) X-ray

X-ray is the oldest and most common type of medical imaging. X-rays are a form of electromagnetic radiation, just like visible light. However, X-rays have much higher energy than visible light and can penetrate the human body.

This property makes X-rays helpful in creating images of the inside of the body. When X-rays pass through the body, they are absorbed to varying degrees by different tissues.

This absorption produces an image on film or a digital detector that a radiologist can interpret.

2) CT scan

A CT scan is a type of medical imaging that uses X-rays to create detailed images of the inside of the body. CT stands for “computed tomography,” which means that a CT scan produces images that are “slices” of the body, similar to how a loaf of bread can be sliced into thin pieces.

CT scans are often used to diagnose brain, spine, chest, and abdomen problems. They can also be used to guide biopsies and surgeries.

3) MRI

MRI stands for “magnetic resonance imaging.” It makes use of magnets that are powerful and radio waves to come up with images of the inside of the body. MRI is often used to image the brain and spine but can also image other body parts.

4) Ultrasound

Ultrasound is a type of medical imaging that uses sound waves to create images of the inside of the body. For example, ultrasound is often used to image the abdomen, pelvis, and breasts. It can also image blood vessels and guide biopsies and surgeries.

5) Nuclear medicine

Nuclear medicine is a type of medical imaging that uses radioactive materials to diagnose and treat diseases. Nuclear medicine procedures can be used to image the brain, heart, lungs, skeleton, and many other body systems.

Nuclear medicine procedures are often used to diagnose cancer, heart disease, and thyroid disorders.

6) Interventional radiology

Interventional radiology is a type of medical imaging that uses X-rays, MRI, ultrasound, and other imaging techniques to guide minimally invasive procedures. Interventional radiology procedures can be used to treat a wide variety of conditions, including cancer, cardiovascular disease, and gastrointestinal disorders.

7) Radiation therapy

Radiation therapy is a treatment for cancer that uses X-rays or other types of radiation to get rid of the cancer cells. Radiation therapy can treat many different types of cancer, including breast cancer, lung cancer, and skin cancer. Additionally, radiation therapy can relieve pain from cancer that has spread to the bones.

Radiation therapy is often used with surgery, chemotherapy, and other cancer treatments.

8) Diagnostic radiology

Diagnostic radiology is the branch of medicine that uses medical imaging to diagnose diseases. Diagnostic radiology includes X-rays, CT scans, MRI, ultrasound, and nuclear medicine.

These are just a few of the different types of radiology procedures that are available. Each has its benefits and risks, and your doctor will decide which is best for you based on your situation.
