1.0 Timing of Brain MRI Brain MRI should take place between 40 -44 weeks of corrected gestational age.
2.0 Informed consent According to the SafeBoosC protocol separate informed consent must be obtained before conducting the brain MRI. Unless it is localy standard care to have an MRI at term equivalent age.
3.0 Which sequences to take The following sequences should be conducted (if software is available at the study site)
1 sagittal T1 SE
2 coronal T2W 1.2mm
3 coronal T1W 3D
4 DWI with ADC-MAP, either coronal or axial
5 DTI 45 directions axial (angulation left-right zero)
See scanning details in the attachment/appendix.
Some general remarks: 1. be sure the whole brain in scanned including the CSF until outside the skull 2. preferable on 3T, second choice 1.5T 3. for T2/T1 we prefer coronal slices, second choice is axonal/transverse slices 4. slice thickness <2mm, for T1 And T2, scan without a gap (gap zero) 5. Scans we prefer: T1 sagittal, t2W, T1W, DWI, DTI

4.0 The Procedure These are suggested guidelines of how to perform a Brain MRI; however, local instructions may be used. There are two ways on performing the brain MRI: either the infant is scanned during natural sleep or under sedation. For sedation oral Cholralhydrate (50-60 mg/kg) may be used. Before starting:
Make sure that the baby’s body suits and clothes are metal free.
If any surgical metal (PDA clip, VP shunt etc) has been used, one needs to check with the surgeons / radiologists whether it is MR compatible metal.
4.1 Natural sleep: When scanning is done during natural sleep it is essential to plan well in advance:
30-60 minutes before the scanning the mother should feed the child
Change the nappy if necessary
Pulsoximetry is applied on the foot - check the signal.
Place MRI compatible electrodes for monitoring heart rate
Ear plugs and ear muffs are applied (a hat may be applied to keep the ear protection in place)
Wrap a blanket tightly around the baby so that the shoulders and arms are within the blanket.
Check the signal of the heart rate.
If you hav a belly-belt for respiratory rate, we recommend to use this as well
If using a vacuum mattress
Wait until the baby falls asleep.
Place the baby on the vacuum mattress on the scanner – please make sure that the baby’s head is in the midline before applying the vacuum.
If using an MRI compatible incubator (with / without a vacuum mattress)
Put the child in the MR-incubator
Wait until the child is a sleep
If using a vacuum mattress: please make sure that the baby’s head is in the midline before applying the vacuum
The Scanning can start. If the baby wakes up consider Glucose drops or feeding again. After the scanning is done, the parent(s) can take the baby home. 4.2 Sedation (with oral Cloralhydrate):
Sedation should be given 45 minutes before scanning starts – oral Cloralhydrate (50- 60 mg/kg).
Pulsoximetry is applied on the foot - check the signal.
Place electrodes for monitoring heart rate- check the signal.
(The baby can be fed as long as it still awake.)
The ear protection and the wrapping of the baby is as in the paragraph “natural sleep”.
After the scanning it is advised to keep the baby for 12-24 hours on the monitor when sedation has been used.
5.0 Saving and transferring data to CTU After the first MRI Manon Benders and Cornelia Hagmann must be alerted in order to check the quality of the images.
The MRI data must be saved in the local archive with patient id
Within one month after the MRI is condusted, a copy of the MRI file either anonymised or called by study-id must be send with FTP (File Transfer Protocol) to the CTU (Copenhagen Trial Unit)
For information regarding the data transferring please go to the SafeBoosC homepage and find the SOP: Data transfer to Copenhagen Trial Unit. Link to the SafeBoosC homepage: www.safeboosc.eu
