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.
