In the context of CT (Computed Tomography), IR most likely refers to Interventional Radiology.
Interventional Radiology (IR) Explained
Interventional Radiology (IR) is a specialized field of medicine where doctors use medical imaging techniques to guide minimally invasive surgical procedures. These procedures are used to diagnose, treat, and sometimes even cure a wide range of medical conditions.
Role of CT in IR
CT scanning is one of the imaging modalities utilized in Interventional Radiology. Other modalities include:
- Fluoroscopy
- MRI (Magnetic Resonance Imaging)
- Ultrasound
How CT is Used in IR
CT imaging provides detailed cross-sectional images of the body, allowing interventional radiologists to:
- Visualize the target area: CT helps to clearly see the specific area within the body where the intervention is needed.
- Guide instruments: The real-time imaging capabilities of CT allow doctors to guide needles, catheters, and other small instruments to the precise location within the body.
- Monitor the procedure: During the procedure, CT scans are taken to ensure the instruments are correctly positioned and that the treatment is being delivered effectively.
Examples of IR Procedures Using CT Guidance
- Biopsies: Using CT to guide a needle to extract a tissue sample for diagnosis.
- Drainage procedures: Placing a drainage tube into an abscess or fluid collection under CT guidance.
- Tumor ablation: Using CT to guide the delivery of energy to destroy tumors.
- Angiography and Stenting: CT can be used to plan and guide procedures to open blocked blood vessels.
