The mission of the MRI Service Center is to explore and investigate all aspects of magnetic resonance research in medicine. The center serves as a research resource for members of the Department of Radiology, Johns Hopkins and the community. It invites and encourages research innovation, as well as collaboration at the local, national and international level, and works to provide state-of-the-art technology to researchers and clinicians.
Our three clinical human MRI scanners are dedicated for research and staffed by three MR technologists who assist with all imaging procedures.
Equipment and Services:
- 3T Siemens TIM Prisma MRI provides multinuclear imaging capabilities and offers a full complement of receiver coils for neurological, musculoskeletal and body imaging. Equipped with 64 independent radio-frequency channels for parallel transmit and receive and high-performance gradients for high signal-to-noise ratio (SNR), speed and enhanced diffusion-weighted MRI (DWI). It has a dockable table to facilitate patient transfer and anesthesia, a video system for functional MRI (fMRI) studies and a 3D neuro-software package for DWI.
- 1.5T short-bore Siemens Espree MRI with a miyabi transfer table connecting a flat-panel, floor-mounted Siemens Axiom Artis Zee angiographic system for cardiac-gated, c-arm/cone beam CT. It is ideally suited for MRI-guided interventional studies and is equipped with a cyro-ablation system.
- 3T Philips Achieva MRI with in-room monitors to facilitate dynamic and interventional studies, 32 receive channels, a patient-adaptive two channel RF shimming, multinuclear MR capabilities (including phosphorus-31P) and a full complement of coils for neurological, musculoskeletal and body MRI. The system has Quasar dual gradients, with gradients up to 80 mT/m, slew rates up to 200 mT/ms, a projection system for fMRI studies, and a secondary table for MRI-guided high-intensity ultra-sound (HIFU) procedures with real-time temperature mapping.
- Work station software for developing and testing new MR pulse sequences.
- Vendor research agreements for work-in-progress sequences and multicenter trials.
