Interventional radiology procedures are most commonly used to identify the cause of an abnormality inside the body in order to properly diagnose and treat patients. These types of procedures can be performed on an outpatient basis and therefore have less risk, less recovery time and less discomfort than surgery.
Using imaging guidance such as ultrasound, or magnetic resonance imaging (MRI), a specially trained doctor will insert a small needle into the abnormal area and remove a sample of the tissue or fluid for analysis.
The sample is then is given to a pathologist who examines it under a microscope to determine whether the abnormal tissue is a non-cancerous tumor, cancer, infection, or scar. Several specimens may be needed for a complete analysis.
Some interventional radiology procedures are done to diagnose illness while others can be for treatment purposes. The range of conditions which can be treated by interventional biopsy is continually growing and the results can give your doctor the information he needs to provide you with the best care and treatment.
