This requires MR-compatible anaesthesia equipment, transferring a sometimes instable patient for a longer time from a paediatric ward to the radiology department and the presence of a doctor responsible for the anaesthesia.
Magnetic-resonance microscopy is now implemented in many laboratories worldwide due to the availability of commercial high-field magnetic-resonance instruments for use in small animals, the development of accessories (including miniature radio-frequency coils), magnetic-resonance compatible physiological monitoring equipment, and access to adjustable anaesthesia techniques.
Based on the final model, a simulation for maintaining steady state concentration for S-ketamine was carried out, targeting a plasma concentration compatible with the maintenance of surgical level of anaesthesia.
Infants were fed and allowed to fall into natural sleep without sedation or anaesthesia, then laid in an MRI-compatible cradle with ear protection, pulse oximetry and vector ECG monitoring.
The procedure is performed with the patient under sedation or general anaesthesia using CAT or MRI guidance (MRI-compatible cryoprobes exist on the market).
However, all reported sedation without deep analgesia, compatible with the use of tiletamine/zolazepam in chemical restraint or initial anaesthesia induction.
The first four images in Fig. 1 show selected frames from the advancement of an MR-compatible RF electrode (Celon AG, Teltow, Germany) in the liver of a patient placed under general anaesthesia, 20 min after the administration of Mn-DPDP.

Drugs, injections, anaesthesia, debt: my heart sinks.
Depth of anaesthesia was closely monitored.
