- Radiofrequency ablation (RFA) is a minimally invasive procedure that destroys cancerous tumors. Pulses of radiofrequency energy are sent through a catheter (a long, thin tube) to heat and destroy diseased tissue. Currently, RFA is a standard treatment for patients with inoperable liver tumors.

Radiofrequency Ablation for Arthritis Pain In this article. Radiofrequency ablation (or RFA) is a procedure used to reduce pain. An electrical current produced by a radio wave is used to heat up a small area of nerve tissue, thereby decreasing pain signals from that specific area.he degree of pain relief varies, depending on the cause and location of the pain. Pain relief from RFA can last from six to 12 months and in some cases, relief can last for years. More than 70% of patients treated with RFA experience pain relief.

RFA for Liver Tumors: Does It Really Work? The use of radiofrequency ablation (RFA) is increasing in the treatment of both primary and metastatic hepatic tumors. However, the role of RFA has yet to be clearly defined in patients who are still considered amenable to surgical intervention.

Metastatic Liver Lesions Diagnosis and Treatment RFA may be used for patients who have unresectable metastatic liver lesions, or are too ill to undergo surgical resection, and may be used in combination with other forms of treatment. Surgery Surgical resection involves removing a portion of the liver that contains the metastatic lesion.

About This Procedure Radiofrequency Ablation (RFA) is an FDA-approved endoscopic technique in which diseased tissue is exposed to heat energy and destroyed. Specialists at the Massachusetts General Hospital Barrett’s Esophagus Treatment Center offer RFA to treat Barrett's esophagus. RFA was first used to treat Barrett’s esophagus in 2005.

Magnetic Resonance Imaging (MRI) - Chest A special form of MRI called magnetic resonance angiography (MRA) is helpful to assess the vessels of the chest cavity (arteries and veins). MRA can also demonstrate an abnormal ballooning out of the wall of an artery (aneurysm) or a torn inner lining of an artery (dissection). See the MRA page for more information.

Radiofrequency Ablation (RFA) / Microwave Ablation (MWA) of Liver Tumors Radiofrequency ablation is used to treat many types of liver cancer. The two most common types are: 1  hepatocellular carcinoma, which is a primary liver cancer (meaning it begins in the liver).

- Magnetic Resonance Angiogram (MRA). Guide. A magnetic resonance angiogram (MRA) is a type of magnetic resonance imaging (MRI) scan that uses a magnetic field and pulses of radio wave energy to provide pictures of blood vessels inside the body.ith MRA, both the blood flow and the condition of the blood vessel walls can be seen. The test is often used to look at the blood vessels that go to the brain, kidneys, and legs. Information from an MRA can be saved and stored on a computer for further study. Photographs of selected views can also be made.

Rapid thermal processing Rapid thermal anneal (RTA) is a subset of Rapid Thermal Processing. It is a process used in semiconductor device fabrication which consists of heating a single wafer at a time in order to affect its electrical properties. Unique heat treatments are designed for different effects.

Magnetic Resonance Angiography (MRA) You might be familiar with the testing procedure called magnetic resonance imaging (MRI) . In this test, radio waves, a magnetic field, and a computer create a scan of your body parts to look for health problems.Magnetic resonance angiography – also called a magnetic resonance angiogram or MRA – is a type of MRI that looks specifically at the body’s blood vessels.Unlike a traditional angiogram, which requires inserting a catheter into the body, magnetic resonance angiography is a far less invasive and less painful procedure.uring a magnetic resonance angiography, you lie flat inside the magnetic resonance imaging scanner, which is a large, tunnel-like tube that takes pictures of your body.

Frequently Asked Questions A receipt date is specified, and the applications submitted in response to the RFA are reviewed and considered together as a group competing for funds. The application must cite the RFA to be considered with that group. A Request for Proposals (RFP) solicits contract offerors to submit their bids and proposals.

Subject: Radiofrequency Ablation of Liver Tumors The cells killed by RFA are not removed, but are gradually replaced by fibrosis and scar tissue. If there is local recurrence, it occurs at the edge, and in some cases may be retreated. Radiofrequency ablation may be performed percutaneously, laparoscopically, or as an open procedure.

Pain Management RFA is a technique used to destroy a nerve through the use of heat. This process can also be called radio-frequency rhizotomy. RFA is frequently used for back pain generated by the medial branch nerves of the facet joints. You will arrive at the George Isaac Center approximately 45 minutes before your scheduled procedure.

Radiofrequency ablation RFA is generally conducted in the outpatient setting, using either local anesthetics or conscious sedation anesthesia. When it is delivered via catheter, it is called radiofrequency catheter ablation.

- Treatment of liver metastases is undertaken to prolong survival and reduce endocrine-related symptoms as well as symptoms related to the hepatic mass. Radiofrequency ablation (RFA) has been investigated as a treatment for unresectable hepatic tumors, both as primary treatment and as a bridge to liver transplant.

- How Does RFA Work? When surgery is not an option, RFA can eliminate tumors without the side effects of other techniques. Here’s how it works. Seek RFA is a very precise procedure. Using an imaging guidance system such as ultrasound, computed tomorgraphy (CT), or magnetic resonance (MR), the physician places a slender probe directly into the tumor.

- Fractora is the most advanced fractional radio-frequency treatment providing anti-aging improvements on skin tone and texture for a more radiant appearance through ablation and skin resurfacing.he most common areas of treatment are the lower eyelid, upper eyelid, smile lines, cheeks, mouth and neck. RF energy heats the skin in a controlled schema to remodel deep collagen and improve the appearance of the skin.

- Radiofrequency ablation: The use of electrodes to generate heat and destroy abnormal tissue. In radiofrequency ablation (RFA), heat is generated locally by a high frequency, alternating current that flows from the electrodes. A probe is inserted into the center of the tumor and the non-insulated electrodes, which are shaped like prongs, are projected into the tumor.

Radiofrequency Ablation (RFA) Radiofrequency ablation uses a special type of needle to apply radio waves to a painful nerve, in turn “stunning” it and relieving the pain. The procedure is referred to by many names: RF, RFA, rhizotomy, and neurotomy. There are several different types of Radiofrequency Ablation: 1  Thermal or Conventional RFA: A radiofrequency current is created which causes energy to pool in the tissue.

Radio Frequency Identification (RFID): What is it? Radio Frequency Identification (RFID) technology uses radio waves to identify people or objects. There is a device that reads information contained in a wireless device or “tag” from a distance without making any physical contact or requiring a line of sight. RFID technology has been commercially available in one form or another since the 1970s. It is now part of our daily lives and can be found in car keys, employee identification, medical history/billing, highway toll tags and security access cards.

- RFA does not cure cancer, but it can effectively destroy cancer cells, possibly in a similar way to surgical removal, relieve pain and suffering, and may prolong life. Radiofrequency ablation (RFA) is a local treatment for cancer that delivers radiation directly to a tumor.
