Improving signal-to-noise ratio in transcranial magnetic resonance guided focused ultrasound
Background/introduction Signal-to-Noise Ratio (SNR) can be increased in Magnetic Resonance Imaging (MRI) using Radio Frequency (RF) coils. Of all the options for increasing SNR, coils provide the greatest gains for the dollars spent. Coils for 1.5 and 3 Tesla MRI systems consist of conductive loops that are tuned to resonate at the fundamental frequency associated with the field strength of the...

Policy [TOP] Magnetic resonance ‒ guided high-intensity ultrasound ablation may be considered medically necessary for pain palliation in adult patients with metastatic bone cancer who failed or are not candidates for radiotherapy. Magnetic resonance-guided high-intensity ultrasound ablation is considered investigational in all other situations including but not limited to: Treatment of uterin...
متن کاملMagnetic resonance-guided focused ultrasound surgery.
Uterine leiomyomas pose a significant health issue to reproductive-age women. Many women desire uterine conservation, and previously safe and efficacious therapies have been limited. Magnetic resonance-guided focused ultrasound surgery is a new noninvasive therapy that has been proven to be both safe and efficacious in the treatment of fibroids.
