Interventional Radiology

Interventional radiology performs invasive imaging procedures to guide other medical procedures, avoiding surgery. In oncology, it has been used to treat some types of cancer, to relieve pain and to diagnose tumors. Learn more.
Interventional Radiology

Interventional Radiology is the area of ​​medicine that covers invasive medical procedures usually performed using needles and/or catheters in which the interventional radiologist (as the specialist in the field is called) uses imaging methods to guide the procedure, not requiring surgical cuts or video surgery cameras.

With the use of these resources, the interventional radiologist is able to precisely locate the target of the procedure (tissue, organ or tumor) and, thus, introduce needles and/or catheters with simultaneous monitoring of the images – making the procedure safe and efficient. The interventional radiologist is able to access deep organs such as the liver, kidneys and bones, without the need for large incisions in the skin and other tissues.

Invasive radiology has been used to treat some cancers that respond successfully to this type of treatment. Procedures include new treatments that relieve pain and diagnose tumors, sometimes without the need for a surgical biopsy.

An example of how this specialty is applied is when the blood system itself is used to deliver chemotherapy drugs through the arteries directly into the tumor.

With invasive radiology, imaging resources such as radiography, angiography, computed tomography and ultrasound, which were historically used only for diagnostic purposes, are combined with surgical instruments to access and treat virtually any organ in the body. This allows the performance of procedures that are proven to be safe, effective and less painful, which result in a reduction in the patient’s recovery time, reducing the rate of complications and, as a result, the length of hospital stay.
