Magnetic Resonance Imaging
- 1.5 tesla GE Signa HDe MRI scanner
- Full range of coils for optimal signal to noise ratio
- Superconducting system gives excellent magnetic field homogeneity and stability affording precise high resolution images and minimum acquisition time. Also allows full range of sequences including 3D high resolution imaging, diffusion weighted imaging (DWI) and apparent diffusion coefficient (ADC) mapping
- Specialist radiologist available to assess the sequences as they are acquired, allowing appropriate and specific sequence selection for each case, coordinating with the Specialist clinician in charge of the case where appropriate
- Dedicated reporting workstation
- Patient safety is paramount
- All anaesthetics monitored by a member of the
Specialist-led anaesthesia team - Remote monitoring of heart rate, blood pressure, pO2...
- MRI trained nursing staff
- All anaesthetics monitored by a member of the
1.5 Tesla superconductor MR unit at Willows Referral Service
