Perinatal Imaging Department
The Perinatal Imaging Department has advanced MR imaging facilities within a dedicated MR imaging suite sited within the Neonatal Intensive Care Unit at St Thomas’ Hospital, as well as access to the other MRI systems Imaging Clinical Research Facility.
Key infrastructure includes:
- 3T Philips Achieva MRI scanner for imaging neonates within the Evelina Newborn Imaging Centre (ENIC)
- Bespoke 32 channel neonatal head coil with a dedicated positioning device allows scans at a much higher resolution than using a normal adult head coil which allows an increased signal to noise ratio (SNR) for accelerated scanning and improved motion correction techniques
- Brain imaging system for neonates which is adapted for imaging preterm babies and for babies that need respiratory aids, such as ventilation
- Bespoke heating mattress and a portable MR compatible ventilation system (Hamilton Ventilator) for transfer of babies from NICU to the MR Unit
- Near infra-red spectrometer which allows researchers to measure oxygenation of the brain
- A wireless in-vivo system that monitors neonates allowing measurement of heart rate, oxygen saturation levels, temperature and blood pressure. This integrated capability allows novel treatments defined by basic and translational neuroscientists to be tested in human infants using novel and well-qualified imaging biomarkers

Imaging Chemistry & Biology
Within the Imaging Chemistry & Biology department, the technical facilities include:

- Molecular biology and radioanalysis facilities, updated with a £1m Wellcome Multi-User Equipment Grant in 2019. This also includes mass spectrometer, multiple radioHPLC facilities and nanoparticle synthesis facilities.
Our tissue perfusion rigs act as intermediate platforms between working with cells in culture and working in small animals in vivo. They allow us to bridge the translational gap between working in isolated cells (with maximal experimental control and opportunity for intervention, but of limited in vivo relevance) and the in vivo situation (with maximal clinical relevance, but limited opportunity for intervention and or/validation of mechanism and imaging agent specificity).
By perfusing isolated organs or whole tissues, we can characterise the structure-activity relationships and pharmacokinetics of novel imaging agents, and validate their specificity in an intact working (and in the case of the heart, beating) organ with an intact vasculature, under exquisite experimental control in terms of oxygenation, energy substrate delivery, pharmacologic intervention etc).
We have two custom-built perfusion rigs coupled to unique triple gamma detection arrays for evaluating and exploiting PET and SPECT imaging agents, and a third rig which allows tissue perfusion within the bore of our 9.4 T NMR magnet. While historically our work has focused on isolated perfused hearts, we are developing an ambitious program to translate the technology to isolated perfused tumours to allow us to study cancer, and develop cancer imaging approaches in an entirely new way.
