Radiofrequency in interventional radiology

Radiofrequency (RF) is a low-risk treatment method. In this method, liver, lung, bone, breast, etc. tumors can be destroyed using radio waves. In fact, the high temperature caused by these waves causes the destruction of cancer cells in the target organ. RF is performed under the guidance of imaging devices without the need for hospitalization and anesthesia. This treatment method is especially suitable for patients who are unable to undergo surgery due to general conditions or tumor location. Embolization or embolotherapy is a semi-invasive method to block blood vessels. This method is used to stop or prevent bleeding. Disabling structures such as tumors is also one of the uses of embolization, which is done by reducing blood supply to the tissue. In this method, objects or materials are introduced into the blood supply system under the guidance of imaging devices to block the desired vessel. These objects and materials include items such as coils, ethanol, microspheres such as polyvinyl alcohol (PVA), gelatin sponges, etc. Embolization plays a role in the treatment of diseases such as aneurysms, vascular anomalies, lymphatic malformation (VM), hemangioma, pulmonary artery fistulas (AVFs) and arteriovenous malformation (AVMs) and bleeding caused by trauma.
