first actively shielded 7t MRI scanner

PALO ALTO, CALIF, 19 January 2010 – Varian, Inc. (NasdaqGS: VARI) announces the successful completion of the world’s first actively shielded 7 Tesla whole-body magnetic resonance imaging (MRI) magnet. Ultra High Field (UHF) MRI at 7T offers unmatched resolution, enabling researchers to visualize exquisite anatomical and functional detail in the human brain or other organs.

Clinical MRI systems use actively shielded magnets at 1.5 or 3 Tesla. Until now, however, UHF MRI magnets have typically required 400 to 800 tons of surrounding iron to form a magnetic shield. This amount of iron must be built into the fabric of the building, limiting the number of sites that can accommodate a UHF MRI research system. Extending active shielding technology to 7 Tesla magnets will allow these powerful research instruments to be more widely available.

The Varian, Inc. Magnet Technology Centre in Oxford, UK has manufactured over 80% of the world’s UHF MRI magnet systems. This, the world’s first 7 Tesla actively shielded magnet, was commissioned by a US government research facility to demonstrate engineering leadership with the goal of having the technology adopted by clinical MRI system vendors. The magnet will be commissioned at its final site in the US in early 2010.

Varian’s Senior MRI Magnet Designer, Rory Warner, stated that the factory tests results were very pleasing. “The new 7T actively shielded magnet performs as expected. It exhibits all the excellent homogeneity and stability characteristics that we had designed for,” he said.

“Varian’s whole-body 7T magnet allows researchers to advance our understanding of human biology with more detailed images,” said Martin O’Donoghue, Senior Vice President, Scientific Instruments, Varian, Inc. “Our active shielding technology makes this powerful tool accessible to a much larger number of scientists and institutions.”

Encompass Group Voluntarily Recalls Thermoflect Product Line

FOR IMMEDIATE RELEASE – December 26, 2009 – McDonough, GA – Jea R. Gackowski, Encompass Group Corporate Compliance Officer announced today the company is voluntarily recalling the Thermoflect product line for relabeling regarding its use in the MR (Magnetic Resonance) environment.

“We are voluntarily recalling the product line from use in the Magnetic Resonance (MR) environment,” Gackowski said. “We are requesting that the Thermoflect blankets and other products not be used in MR conditional or MR compatible environments. We are in the process of sending labels to our customers to be attached per instructions to remind the hospitals that the product line should not be used in the MR environment.

“In the past, we have stated that the Thermoflect product may be used in the MR environment. However, after being informed by the FDA, at this time we will not promote the products for use in the Magnetic Resonance Environment. However, the product is still safe and effective for use in treating hypothermia.”

We have been advised by the FDA that a report has been filed of an injury to an (MRI) patient. Several items are under consideration, including all of the blankets used in the MRI environment, of which Thermoflect is one. There is no evidence that the Thermoflect blanket caused the injury but as a precautionary measure we are voluntarily recalling the product line for relabeling.

MEETING DESCRIPTION:
ABOUT THE MEETING

The meeting at the Wynn Las Vegas begins on April 12, 2010 with formal lectures scheduled throughout the day. (Registration will be held on Sunday, April 11, 2010 from 5:00 – 6:00 PM). Question and answer sessions complement the teaching program and provide for interaction between registrants and the faculty.

This symposium provides a practical, comprehensive review of the important aspects of clinical MRI/MRA of the head & spine. Physicians and technologists practicing neuroradiography utilizing MRI should expand their knowledge base and obtain additional information on safe and efficient scanning protocols. A special non-accredited segment of the program focuses on equipment comparisons and capabilities. Those registrants planning to purchase MRI equipment should find this Wednesday morning session particularly valuable as companies discuss their present capabilities and their plans for the future.

TARGET AUDIENCE

This CME activity is primarily intended and designed to educate those physicians who supervise and interpret neuroradiology MRI studies. Thus, it should be particularly helpful for radiologists, neurologists, and neurosurgeons. This CME activity should also be useful for referring physicians who order these studies so that they might gain a greater appreciation of the strengths and limitations of clinically relevant neuroradiography.

EDUCATIONAL OBJECTIVES

Attendees should, at the completion of this course, be able to:

Describe expanded applications and pitfalls for MRI/MRA as it applies to neuroradiography
Recognize the MRI appearance of normal anatomy and common pathology
Incorporate protocols to effectively assess patients with CNS pathology
Discuss the clinical benefits of functional imaging, perfusion, and diffusion imaging techniques
Effectively assess stroke patients using MRI techniques
Incorporate state of the art imaging protocols and techniques for assessment of the spine into clinical practice

INSTRUCTORS:
Feller, Johnson, Ross, Tanenbaum, Tirman, Truwit, Watanabe

CME HOURS: 18.75
