What Is Interventional Radiology?

Interventional radiology (IR) is a medical specialty that uses imaging tools — like X-rays, CT scans, MRI, and ultrasound — to guide doctors as they perform treatments inside the body.

Through the use of precise, image-guided techniques, IR enables doctors to treat conditions such as internal bleeding, tumors, and clogged blood arteries.

Instead of large incisions used in traditional surgery, IR relies on small cuts and thin instruments. This less invasive approach often results in reduced pain, lower risk of complications, and a quick recovery for patients.

How IR Works

IR uses advanced imaging tools like MRI (magnetic resonance imaging), CT scans, ultrasound, and fluoroscopy to see inside the body in real time. Doctors use these images to guide their instruments during procedures, ensuring they reach the precise area that needs treatment.

Instead of making large, deep cuts like in traditional surgery, doctors make tiny incisions and use slim tools such as needles, catheters, and guidewires. These instruments are carefully inserted through tissues or blood vessels to reach the problem area.

Because of this, they can treat conditions like infections, tumors, or clogged arteries with less pain, lower risk, and faster recovery times than traditional surgery.

Conditions and Procedures in IR

Interventional radiologists are medical specialists who use imaging technology to perform precise, minimally invasive treatments and treat a variety of ailments. Their experience allows patients to avoid traditional surgery, which leads to a quick recovery, less discomfort, and fewer complications.

These specialists use real-time imaging to guide small instruments through the body and treat a wide range of conditions with great accuracy. The following sections highlight the most commonly treated conditions and the procedures used to manage them effectively.

Commonly treated conditions

IR offers a less invasive alternative to treat a wide range of medical issues. By employing imaging to guide each step of the procedure, IR helps patients recover more quickly and comfortably. IR is commonly used for:

• Blood clots: Doctors remove or break up clots inside veins or arteries without open surgery
• Tumors: IR can treat certain tumors by delivering medicine or heat directly to them, avoiding major operations
• Uterine fibroid: IR blocks blood flow to fibroids in the uterus to shrink them, helping relieve symptoms without needing a hysterectomy
• Varicose veins: Damaged veins are sealed off using laser or other techniques to improve blood flow and reduce pain

Procedures in focus

IR treatments are performed with image guidance, allowing doctors to navigate precisely and treat conditions effectively. Key procedures include:

• Angioplasty: A miniature balloon is gently expanded inside a tight or blocked vessel, clearing the path for blood to flow again.
• Embolization: Blood flow is blocked to tumors or fibroids, helping shrink or stop their growth.
• Tumor ablation: Doctors use heat, cold, or chemicals to destroy tumors in the lungs, liver, or kidneys.
• Biopsies: With the help of imaging, doctors take a small piece of tissue from deep or hard-to-reach areas to check for problems like cancer — without needing major surgery.

Benefits of IR

IR offers several advantages that make treatment safer, quicker, and more comfortable for patients, including:

• Minimally invasive: Procedures involve few or no incisions, resulting in less pain, minimal scarring, and quicker healing
• Shorter recovery times: Patients heal faster and often return to their normal activities sooner than they would after traditional surgery.
• Reduced risk of infection: Infections and other complications are less likely to occur with smaller incisions.
• Lower cost than surgery: Procedures often cost less than open surgery since they’re simpler and involve shorter hospital stays.

Becoming an Interventional Radiologist

If you’re drawn to a medical career that combines advanced technology with hands-on patient care, IR may be the right choice. This field involves performing detailed procedures using real-time imaging, which calls for extensive training and experience.

In the following sections, we’ll explore the education and certification required to become an interventional radiologist, along with the career outlook.

Education and training

Becoming a skilled interventional radiologist requires a strong academic foundation and extensive hands-on training. Since this field relies on advanced imaging, physicians must develop both in-depth medical knowledge and practical procedural experience.

The journey often begins with a four-year undergraduate degree, typically in a science-focused discipline like biology or chemistry. This is followed by four more years of medical school to earn an MD or DO degree.

After graduation, students often complete a four- to five-year diagnostic radiology residency, where they learn how to thoroughly interpret medical images and perform related procedures. The next step is a one- to two-year fellowship that offers specialized training in performing image-guided treatments.

To become a fully certified interventional radiologist, one must complete around 13 to 15 years of study and training beyond high school.

Required certifications

Certifications are essential for demonstrating a physician’s qualifications and skills and are often required by hospitals and employers.

In the United States, after finishing medical school and residency, doctors must pass the USMLE or COMLEX-USA exams to get their medical license.

They must then earn board certification from the American Board of Radiology (ABR). The ABR offers a combined certification in Diagnostic Radiology and Interventional Radiology, which involves passing both written and oral exams.

Board certification is necessary for most positions and indicates that a doctor meets national standards. To maintain certification, interventional radiologists need to complete regular continuing medical education (CME) to stay updated on new procedures, technologies, and safety practices.

Career outlook and salary

IR is a rapidly growing field with strong job demand driven by an aging population and the increasing preference for minimally invasive procedures. As healthcare continues to adopt image-guided treatments, the need for skilled interventional radiologists is expected to increase.

In the U.S., interventional radiologists are among the highest-paid medical professionals. Recent data shows average annual salaries range from $146,000 to over $273,000, with some positions offering up to $475,000, depending on location, experience, and practice setting.

Job growth is promising, with employment for radiologists projected to grow by 6% between 2023 and 2033. Additionally, many current radiologists are nearing retirement, creating more opportunities for new professionals entering the field.
