Image-guided surgery was originally developed for treatment of brain tumors using stereotactic surgery and radiosurgery that are guided by computed tomography (CT), magnetic resonance imaging (MRI) and positron emission tomography (PET) via technologies such as the N-localizer [11] and Sturm-Pastyr localizer.
These techniques are known as Magnetic Resonance guided Focused Ultrasound Surgery (MRgFUS) [32] [33] and Ultrasound guided Focused Ultrasound Surgery (USgFUS) respectively. [ 1 ] [ 34 ] MRgFUS is a 3D imaging technique which features high soft tissue contrast and provides information about temperature, thus allowing to monitor ablation.
Endovascular therapy is a procedure performed by neurointerventionalists to remove or dissolve the thrombus (clot) and restore blood flow to parts of the brain. Using a catheter that is directed through the blood vessels in the arm or leg up to the brain, the interventionalist can remove the thrombus or deliver drugs to dissolve the thrombus ...
Patients are usually fitted with Class 3 (30-40mmHg) graduated compression stockings and/or bandages for up to 12 hours weeks. Duplex ultrasound is used during follow-up to assess the success of treatment, if there is a need for additional sclerotherapy or any deep vein thrombosis that has formed as an EHIT secondary to procedure.
Contrast-enhanced ultrasound (CEUS) is the application of ultrasound contrast medium to traditional medical sonography. Ultrasound contrast agents rely on the different ways in which sound waves are reflected from interfaces between substances. This may be the surface of a small air bubble or a more complex structure.
Despite the many advantages these therapies provide, "approximately 10% of individuals cannot benefit from modulators due to their genetic mutations or ability to tolerate the treatment," says Boyle.
Radiofrequency ablation is a minimally invasive procedure used in the treatment of varicose veins. It is an alternative to the traditional stripping operation. Under ultrasound guidance, a radiofrequency catheter is inserted into the abnormal vein and the vessel treated with radio-energy, resulting in closure of the involved vein.
Dementia impacts millions of older adults, but researchers are still learning how, exactly, to prevent this devastating illness. Now, research suggests that increasing your intake of one specific ...
