Given the frequent challenges in magnetic resonance imaging that are associated with claustrophobia, this author discusses innovations in noise reduction, radiofrequency coils and wide bore scanners, and emphasizes keys to relieving patient anxiety.

Utilized for neurological procedures including biopsies, catheter placement and electrode introduction, the SmartFrame OR Stereotactic System can be combined with preoperative MRI or CT to ensure optimal placement of devices and instruments.

For women with dense breasts, abbreviated breast MRI and digital breast tomosynthesis (DBT) both offered greater than 98 percent sensitivity rates and greater than 94 percent negative predictive values (NPVs) for breast cancer detection, according to newly published research.

Featuring a lightweight body contouring design, the Small Body Array reportedly facilitates optimal signal-to-noise ratio (SNR) and between 10 and 40 percent faster throughput.
