Xuanwu Hospital (CHINA-INI) Successfully Performs First Cranial Resection Case With Intraoperative MRI


by Jie Tang and Ye Li, Xuanwu Hospital Neurosurgery Department


Beijing, China, April 5, 2019 — On the morning of March 1, 2019, Xuanwu Hospital Neurosurgery Department (China International Institute of Neuroscience, CHINA-INI) performed the first intracranial resection case under the guidance of a 3.0T high field intraoperative MRI system, which signifies the neurosurgery department of Xuanwu Hospital CHINA-INI has entered a new era of precision neurosurgery.

The principle of modern neurosurgical treatment for brain tumors is ‘the greatest degree of safe resection’. The high field iMRI system at Xuanwu Hospital Neurosurgery CHINA-INI has a moving magnet, which is safely separated from the operating room by an RF-shielded door. The magnet can be moved toward the operating room whenever necessary, assisting the surgeon in real-time to determine the degree of lesion resection and protect the important cerebral function.

The lesion is adjacent to important motor-related nerve fiber bundles.


The first patient for iMRI surgery showed one-sided dyskinesia and repeated seizures before operation. Imaging results indicated a left frontal cavernous vascular malformation. The preoperative plan of multimodality neuro-navigation indicated that the lesion was adjacent to and even partially destroyed important motor-related nerve fiber bundles.

The advantages of the intraoperative MRI system are: the patient does not need to be moved and routine surgical instruments, microscopes, and navigation systems can be used, which ensures normal procedural operation and patient safety.


High field MRI effectively guarantees high quality intraoperative images, and provides real-time guidance and precise positioning.


With the assistance of the Anesthesia and Nursing teams, Neurosurgery Chief Physician, Jie Tang, removed the cranial lesions with high field iMRI and a multimodality neuro-navigation system. The intraoperative images indicated a total resection of the lesions and no neurological dysfunction was aggravated after operation. During the operation, with personal instruction from Professor Samii, President Guoguang Zhao, and Professor Feng Ling, and with support from Anesthesiology Director Tianlong Wang, and Chief Nurse, Ting Liu, Operating Rooms, we achieved the first iMRI case perfectly.

During the intraoperative scan, President Guoguang Zhao said, “The iMRI system is not only used in the neurosurgical operating room, but is also an important open platform combined with the cooperation of various disciplines including Imaging and Anesthesiology. Driven by innovation, the use of iMRI will inevitably deepen the intimate cooperation between disciplines and enrich the connotation of the construction of various disciplines.”


The intraoperative MRI system is an open platform with multidisciplinary intersections.


Jie Tang, iMRI system leader for Xuanwu Hospital Neurosurgery, CHINA-INI said, “In traditional surgery, due to intraoperative cerebrospinal fluid loss, brain tissue edema, or tumor resection and other factors ‘brain drift’ will occur. If the operation is guided by pre-operative images, there will be obvious deviation and it could even be misleading. High field iMRI provides the latest images during operation in real-time, correcting the ‘brain shift’ and maximizing resection, while protecting important structures of the brain, realizing real-time positioning, and enabling precise treatment.”

“The application of high field iMRI of CHINA-INI not only maintains the ‘maximum safe resection of tumors’, it will also be an important opening platform for image-guided surgery and brain function research for CHINA-INI. We will further integrate iMRI guided focused ultrasound therapy, tumor cryoablation and laser surgery, and other international advanced minimally invasive treatment technologies to provide the most advanced medical services for patients. We have established a multidisciplinary medical research team specializing in neurosurgery, biomedical engineering, and computer-aided medical image processing, providing unlimited power for neuroscience research and guiding us to explore the mysteries of the brain.”

Prince Sultan Military Medical City Signs Agreement to Build First IMRIS Surgical Theatre in Saudi Arabia

Minneapolis, Minnesota, U.S.A. (7 December, 2018) – IMRIS, Deerfield Imaging, the global leader in intraoperative MRI, announced today that Prince Sultan Military Medical City (hereafter referred to as ‘PSMMC’), in collaboration with distributor Gulf Medical Company, signed a formal agreement to install the first IMRIS Surgical Theatre in Saudi Arabia. Construction at the PSMMC site is currently underway, with anticipated completion in late 2019.

The IMRIS Surgical Theatre uniquely provides intraoperative imaging by transporting the MR scanner between rooms on a ceiling-mounted rail system. At PSMMC, the new IMRIS Surgical Theatre will be a two-room configuration — one room for surgery and the other for diagnostic scanning for outpatient needs. The scanner travels directly to the patient while the patient remains stationary on the operating table. Keeping the patient stationary reduces the risk of infection. With real-time visualization of the anatomy, neurosurgeons can evaluate their progress and confirm results, which reduces the need for follow-up surgeries. Intraoperative imaging also enables neurosurgeons to use perform minimally-invasive procedures, such as deep brain stimulation (DBS) and laser interstitial thermal therapy (LITT).

Formerly known as Riyadh Military Hospital, PSMMC is located in the heart of Riyadh City, the capital of Saudi Arabia. It is considered to be one of the most advanced medical centers in the Middle East. PSMMC is the Medical Services Department (MSD) of the Ministry of Defense and Aviation (MODA). Gulf Medical Company is one of the largest distributors in Saudi Arabia, and has vast experience working with medical device companies for large, turnkey hospital projects like the IMRIS Surgical Theatre at PSMMC.

“We enthusiastically look forward to this upcoming project that will definitely act as a cornerstone for a new era for IMRIS in the kingdom of Saudi Arabia,” said Emad M. Farid, Area Manager, Central Region – KSA for Gulf Medical Company.”

IMRIS Enters Stroke Market with Worldwide Distribution Agreement for VasSol’s NOVA® Quantitative MRA Software


Minneapolis, Minn. (December 3, 2018) – IMRIS, Deerfield Imaging, global leader in the hybrid OR market, today announced entry into the stroke market with a global distribution agreement to sell VasSol, Inc.’s NOVA® Quantitative MRA software.

Every year, over 900,000 Americans experience a stroke or transient ischemic attack (TIA) caused by insufficient blood flow to the brain. Known as an ischemic stroke, it is the most common type of stroke and the leading cause of disability in the United States. The high risk of recurrence in stroke survivors is a major public health concern.

NOVA Quantitative MRA is a powerful diagnostic tool that gives stroke specialists the ability to quantify cerebral hemodynamics and to help assess risk of stroke. NOVA-Neuro is the first commercially available software to use a 3D model-based approach for MR flow measurement.

“NOVA is a powerful tool that provides critical information impacting the care and treatment of patients who have compromised cerebral vascular blood flow which can be life threatening. This partnership with IMRIS will put NOVA in the hands of more hospitals and clinicians around the world so they can treat their patients more effectively,” said Dr. Fady T. Charbel, Professor and Head of the Department of Neurosurgery at University of Illinois, Chicago. Dr. Charbel is an internationally recognized clinical expert in cerebral revascularization; bypass, carotid, and vertebral artery surgery; and a co-inventor and developer of NOVA.

For the past 20 years, similar clinical applications have made phase contrast MR flow measurement the standard of care in cardiovascular MRI. Now NOVA provides neurosurgeons and neuroradiologists this essential tool to apply those same principles to quantitative flow measurements in cerebral vasculature.

“IMRIS is excited to bring this impactful technology to the market and to our expanding global customer base. IMRIS is uniquely positioned in this market segment to help positively impact patient outcomes with the NOVA technology based on our organization’s expertise in both MRI and the neurosciences,” said Robert Korn, Senior Vice President of Global Sales and Marketing for IMRIS.

Leading U.S. Cancer Center to Build New Hybrid OR at New York Site in Conjunction with IMRIS

Unique solution for MR scanner will be first of its kind

Minneapolis, Minn., (November 26, 2018) – IMRIS, Deerfield Imaging, global leaders in the hybrid operating room market, announced today that Memorial Sloan Kettering Cancer Center signed a formal agreement to design and build a new IMRIS Surgical Theatre at their New York City location. Memorial Sloan Kettering is planning to upgrade their existing intraoperative MRI suite. Construction will begin in February 2019, with anticipated completion in July 2020.

The new IMRIS Surgical Theatre at Memorial Sloan Kettering will be a two-room configuration – an operating room and an adjacent room to house the new MR scanner. The scanner will travel between the two rooms on a ceiling-mounted rail system.

The biggest challenge was to design a state-of-art IMRIS Surgical Theatre, complete with ceiling-mounted moving MR scanner, within the footprint of the existing MRI suite. IMRIS software engineers met this challenge by developing a software program to accommodate rotation of the MR scanner. Upon command, the scanner will rotate into linear position, and then move into the operating room to scan patients during surgery.

The intraoperative imaging suite at Memorial Sloan Kettering will be the first of its kind – an example of how IMRIS consults with their customers to design innovative solutions to work around the unique challenges at each institution.

IMRIS provides intraoperative imaging by transporting the MR scanner between rooms. The scanner travels to the patient while the patient remains stationary on the operating table. Keeping the patient stationary reduces the risk of infection and other potential complications. With real-time visualization of the anatomy, neurosurgeons can evaluate their progress and confirm results, which reduces the need for follow-up surgeries. Intraoperative imaging also enables neurosurgeons to perform minimally-invasive procedures such as deep brain stimulation (DBS) and laser interstitial thermal therapy (LITT).
