Find the Special Treatment of Cancer Through the Technique of Interventional Radiology

Interventional radiology (IR) – sometimes called as vascular and interventional radiology (VIR) – is a sub branch of radiology in which minimally invasive treatment procedures are performed by using image guidance. Its procedures are used for the diagnostic purposes. This technique uses the radiofrequency ablation to produce images to direct the treatment procedures. These images are required to direct the setting of needles and other tiny instruments like catheter (small tube). With the help of images, the interventional radiologist guides these small instruments through the body to the area of infected parts. Now radiologists are able to insert a small heat probe into the tumor to kill the damaged cells and to treat other vascular problems.

The common interventional imaging modalities include computed tomography (CT), ultrasound, magnetic resonance imaging (MRI) and fluoroscopy. The oncologists can use these techniques for the treatment of cancer. Pediatric oncologist also finds them useful for the better treatment. Fluoroscopy and computed tomography use ionizing radiation and both methods have the advantages of being fast and geometrically accurate. Though ultrasound may produce the poor image quality and tissue contrast problems, but it is an inexpensive and fast solution to the patients. The MRI provides superior tissue contrast required for the specialized instruments for the treatment of cancer.

The pediatric radiologists use the radiology techniques for the imaging of fetuses, children, infants and adolescents. There are some common procedures of interventional radiology that the physicians have to perform for the treatment. Some of the procedures are as angiography, chemoembolization, drain insertions, embolization, thrombolysis, biopsy, radiofrequency ablation, IVC filter, etc. The interventional radiologists use mainly five types of catheters to inject into the body such as diagnostic angiographic catheters, micro catheters, drainage catheters, balloon catheter and central venous catheter.
