Image-Guided Interventional Procedures

Radiologists are not limited to just analyzing imaging exams, but also play an essential role in interventional procedures guided by these images. These procedures, performed with the aid of cutting-edge technology, allow the radiologist to perform interventions with high precision, ensuring greater safety and effectiveness in the treatment of various medical conditions.

Image-Guided Biopsies

One of the main functions of radiologists in interventional procedures is performing biopsies. When it is necessary to collect a tissue sample for diagnosis, the image is used to locate with precision the area to be biopsied. This is especially important in difficult-to-access locations or for small tumors, where precision is essential. Image-guided biopsy, whether by ultrasound, tomography, or magnetic resonance imaging, offers a less invasive and safer alternative, minimizing the risks associated with the procedure.

Drainage and Fluid Removal

Another example of an interventional procedure is the drainage of accumulated fluids, such as abscesses or liquids in body cavities. These procedures are commonly guided by real-time images, which allows the radiologist to insert a needle or catheter precisely, reducing the risk of injury to nearby tissues. Image-assisted drainage is an effective way to treat conditions that cause fluid accumulation in the body, such as in cases of infection or post-surgical complications.
