Built on the high-definition platform you know and trust, ONI MSK allows you to see more, do more and expect more than ever before.

2x Higher Gradient Strength Increases Visualization of Detail The 70 mT/m gradient strength of the MSK Extreme 1.5T and a fast constant slew rate of 200 T/m/s enables the system to achieve compressed echo trains of > 5 ms. This allows you to collect more data in each image acquired, so you can visualize more detail.

v-SPECTM Technology Improves Accuracy ONI’s exclusive v-SPEC coils are scalable to MSK anatomy and patient size. This increases the MRI signal in your defined region of interest, and gives you more precise information than ever before. With the precision power of v-SPEC, you get better pre-operative screening data, enabling you to optimize your time in surgical procedures.

Sweet Spot Imaging Puts You in Control The MSK Extreme 1.5T puts the physician in complete control of image optimization. Since the system is designed specifically for extremity applications, no surface coils are required, and the patient anatomy is always in the iso-center of the magnet. The patient is reclined in a comfortable seated position, and all imaging areas —even elbows —are now at the true iso-center of the system. This eliminates motion, reduces noise and improves image contrast.
