What is CT guided radiofrequency ablation?
CT-guided RFA is a rapid, percutaneous, minimally invasive, day-care interventional procedure which has treatment outcomes comparable to surgery.
This procedure is technically more feasible at locations which are otherwise difficult to approach by surgery, for example acetabulum, intra-articular femur..
What is CT radio frequency ablation?
After local anaesthesia, a radiofrequency ablation needle is inserted to the target nerve under imaging guidance (ultrasound or CT).
A thin probe is then passed through the needle, which is connected to a radiofrequency generator that results in heating of the probe tip..
What is percutaneous radiofrequency ablation?
In percutaneous radiofrequency (RF) ablation (RFA) of liver tumors, a needle is inserted into the liver, usually under the guidance of ultrasonography (US) or computed tomography (CT).
Once the needle is placed within the tumor, a generator is used to deliver a rapidly alternating current (RF energy)..
What is RFA procedure in CT scan?
During an RFA a musculoskeletal radiologist uses a CT scanner--a high-tech version of an X-ray--to locate a tumor and then guide a specialized needle-like probe into it.
A radiofrequency current then is passed through the electrode to heat the tumor tissue near the needle tip and ablate or eliminate it..
What is the advantage of RFA?
Some advantages of radiofrequency tumor ablation include:
Effective treatment for small cancers.Minimally invasive with no skin incision.Minimal risk to patient.Typically little or no pain.Short hospital stay.The procedure can be repeated if new cancer appears..What is the principle of radiofrequency ablation?
Principle of RFA
In RFA, the high-frequency alternating current from the electrode generates marked agitation of the ions in the tissue that surrounds the uninsulated tip of the probe.
The frictional heat results in thermal coagulation necrosis of the surrounding tissue..
What is the use of radiofrequency ablation?
Radiofrequency ablation, or RFA, is a minimally invasive technique that shrinks the size of tumors, nodules or other growths in the body.
RFA is used to treat a range of conditions, including benign and malignant tumors, chronic venous insufficiency in the legs, as well as chronic back and neck pain..
- In percutaneous radiofrequency (RF) ablation (RFA) of liver tumors, a needle is inserted into the liver, usually under the guidance of ultrasonography (US) or computed tomography (CT).
Once the needle is placed within the tumor, a generator is used to deliver a rapidly alternating current (RF energy). - Radiofrequency ablation (RFA), also known as rhizotomy, is one of the newest pain control techniques.
In this nonsurgical procedure, radiofrequency waves are delivered to certain nerves, with the goal of interrupting pain signals to the brain. - What is it? Computed tomography (CT)-guided radio frequency ablation is a procedure utilizing electrical currents produced by radio waves to ablate (destroy) parts of the heart's electrical conduction system, tumors or other diseased tissue.
