Through IR, both diagnostic and therapeutic procedures can be performed via very small incisions or natural body openings. Diagnostic IR procedures aim to assist in making a diagnosis or guide further medical treatment. For example, performing a biopsy of a tumor under image guidance or using imaging by injecting a contrast agent into a hollow structure such as a blood vessel or duct. Therapeutic IR procedures provide direct treatment. Examples of such applications include catheter-based drug delivery, medical device placement (e.g., stents), and angioplasty of narrowed structures.
Interventional Radiology
Interventional Radiology (IR) is a subspecialty of medicine that performs a variety of minimally invasive procedures using medical imaging guidance such as X-ray fluoroscopy, computed tomography, magnetic resonance imaging, or ultrasound.
The main benefit of interventional radiology techniques is the ability to access deep structures in the body through a natural opening or a small incision using small needles and wires. This reduces risks and pain compared to open surgeries and shortens the recovery time. Real-time imaging obtained during IR also provides precise guidance, enabling more accurate diagnosis or treatment of the condition.
