The MR 7700 3T magnetic resonance imaging (MRI) is a high-accuracy imaging system developed by Royal Philips, a health technology company based in the Netherlands.

The system can be used for research and advanced clinical diagnostics and helps to address the Quadruple Aim, a framework aimed at improving healthcare and reducing costs.

The MR 7700 received 510(k) clearance from the US Food and Drug Administration (FDA) in May 2022.

Design and features

The MR 7700 features XP gradients with a maximum amplitude of 65 milli Tesla per meter (mT/m) and a maximum slew rate of 220 Tesla per meter per second (T/m/s) for each cartesian axis. It can achieve up to 20% more functional MRI (fMRI) sequences, with the same spatial resolution due to shorter repetition times (TRs).

The XP gradients help in delivering high-quality diffusion imaging of all anatomies with 35% higher signal-to-noise ratio (SNR) and 35% shorter scans compared to Philips’ existing Ingenia Elition 3.0T X MRI scanner. The higher SNR provides increased spatial resolution and improves clinical confidence in diagnosis.

The scanner combines conventional proton magnetic resonance imaging and spectroscopy with imaging based on sodium, phosphorus, carbon, fluorine and xenon through the use of a dual-tuned head coil. The multi-nuclei and conventional proton MR exams can be conducted using the same coil without the need to switch MRI coils.

The feature allows radiologists to image six different nuclei across all anatomies, which improves anatomical and metabolic or functional imaging in the areas of neurology, pulmonology and oncology. The enhanced imaging capabilities improve clinical decision-making while also enabling the addition of essential metabolic information to MR exams needed for complex research programmes.

The system also features the MultiBand SENSE clinical application that supports 50% more diffusion tensor magnetic resonance imaging (DTI) to be achieved within the same scan time.

MR 7700 user interface and AI technology

The MR 7700 features an easy-to-use and user-friendly interface that enables scientists and clinicians to easily access the system without compromising on workflow. It includes artificial intelligence (AI)-driven touchless patient sensing and motion detection capabilities that help in addressing the rise in patient volumes experienced by many radiology departments.

The SmartWorkflow feature guides operators with multiple aspects such as exam set-up, patient positioning, coil element selection and in-room examination start. It also reduces operator load in the control room by automating exam planning and scanning, patient guiding through announcements and post processing.

The scanner supports remote monitoring, remote diagnostics and remote field support, enabling more than 500 parameters to be monitored and detected remotely. Any issues with the system can be resolved remotely without impacting the department operations.

Imaging solutions

The MR 7700 is equipped with unique imaging solutions such as 3D Amide Proton Transfer (APT), black blood imaging, and susceptibility weighted imaging (SWIp). 3D APT is an innovative contrast-free imaging solution that helps in differentiating high-grade gliomas and tumour progression, while black blood imaging can help in 3D brain imaging with higher image resolution.

SWIp offers 3D weighted brain imaging that can be used in combination with clinical information to diagnose neurological pathologies.

Marketing commentary on Royal Philips

Royal Philips provides diagnostic imaging, patient monitoring and health informatics solutions, in addition to consumer health and homecare solutions. The company operates across 100 countries and employs more than 79,000 people globally.

The MR 7700 is the latest innovation in Royal Philips’ radiology portfolio of scalable high-performance MR systems. The MR 5300 1.5T helium-free MRI scanner and the Ingenia Elition 3.0T X are some of the other latest products launched by the company.
