MRgFUS Offers Noninvasive Treatment for Breast Cancer


Focused ultrasound under MR guidance may offer a safe and effective noninvasive treatment for breast cancer, according to research presented at RSNA 2013. MR-guided focused ultrasound (MRgFUS) ablation requires no incision or puncture to perform. Instead, it uses the acoustic energy from high-intensity focused ultrasound to heat and ablate diseased tissue. Continuous MRI is used to locate the lesions and …
