The term interventional radiology refers to a set of practices that are performed under a minimally invasive treatment process. It makes use of image guidance technology to have higher precision in the treatment process. The images are considered for a direct treatment process that includes the use of a needle or other tiny instruments like catheters or small tubes. An interventional radiologist makes use of these instruments to the body to reach the damaged area. The technique has significantly improved the diagnosis of perilous diseases like cancer. The message is executed only for diagnostic purposes like an angiogram.
The method makes use of intervention modalities like magnetic resonance imaging, fluoroscopy, computed tomography, and ultrasound scanner. The process includes the use of ionizing radiation to facilitate geometrically accurate and quick treatment. Similarly, MRI is capable of offering superior tissue contrast but it requires specialized instruments.
Following are some of the common interventional radiology techniques
Balloon angioplasty
The doctor makes use of small balloons on the tip of the catheter for widening the narrowed vessel.
Angiography
It is a type of X-Ray imaging for blood vessels to identify narrowing or blockage inside the vessel. Doctors make use of infrared images for inserting small stains to inflate and open the vessels.
Chemoemobilizaton
Using this treatment the tumor is created directly through its blood supply. Doctors make use of clot-inducing agents to keep a check on the blood flow inside the artery.
Needle biopsy
Small needles are inserted into the damaged part of the body for guided imaging. Kind of imaging can also be performed without using surgical intervention.
