is a field of medicine that detects and treats illnesses using imaging technologies.

Diagnostic radiology and interventional radiology can be split into two distinct fields.

Radiation therapy (also called radiotherapy) is a cancer treatment that destroys cancer cells and shrinks tumors using heavy doses of radiation. In x-rays, radiation is used to see inside the body at low doses, as in x-rays on your teeth or broken bones.


Diagnostic radiology lets health care providers see structures within the body. Diagnostic radiologists are called doctors who specialize in the interpretation of these images. The radiologist or other doctors will also make use of the diagnostic images:

Diagnose the cause of the symptoms you have

Track how much the body responds to the medication you get for your sickness or disease.

Screening for various diseases, such as breast cancer, cancer of the stomach, or heart disease

The most popular forms of radiology diagnostic examinations include:

Computerized tomography (CT), also referred to as computerized axial tomography (CAT) scan, like CT angiography,

Fluoroscopy, including upper GI and enema of barium


Magnetic resonance imaging (MRI) and angiography with magnetic resonance (MRA)


Nuclear medicine, which involves examinations such as a bone scan, thyroid scan, and heart stress thallium test

Plain x-rays, including chest x-rays,

When paired with CT, positron emission tomography, also known as PET imaging, PET scan, or PET-CT, Ultrasound

Radiology Interventional

Physicians who use imagery such as CT, ultrasound, MRI, and fluoroscopy to help guide treatments are interventional radiologists. Imaging aids the doctor as you inject catheters, cords, and other tiny equipment and devices into the body. Usually, this facilitates smaller incisions (cuts).

Instead of actually looking into the body through a scope (camera) or through open surgery, doctors may use this device to diagnose or treat symptoms in nearly every part of the body.

Interventional radiologists are also involved in the treatment of cancers or tumors, artery and vein blockages, uterine fibroids, back pain, liver issues and problems with the kidneys.

The practitioner should not make an incision, or only a very small one. Since the treatment, you rarely need to stay in the hospital. Most individuals only require mild sedation (medicines to help you relax).

Examples of procedures in interventional radiology include:

Angiography or angioplasty and the positioning of stents

To control bleeding, embolization

Treatments for cancer, including tumor embolization by chemoembolization or radioembolization of Y-90

Tumor ablation, cryoablation, or microwave ablation of radiofrequency ablation

Kyphoplastia and vertebroplasty

Needle biopsies of multiple tissues, including the lungs and thyroid gland.
