Current treatment methods for intracranial aneurysms include surgical clipping or endovascular embolization with coils, particles or a coagulable material such as Onyx. These methods require either significant surgery or the introduction of foreign bodies into the patient and the risk of an immune reaction. Previous research has successfully shown the coagulation of tissue using radio frequency (RF) energy harvested from the MR scanner. We present an aneurysm treatment method proof-of-concept that consists of coagulation of Human Serum Albumin, a naturally occurring protein in the blood, using MR RF ablation.
