Learning Objectives
Understand the need for an MRI compatible neonatal incubator (MRIcNI)
Review the clinical and research potential of the MRIcNI,
with particular reference to brain injury and neurodevelopment in premature infants
Background
Premature birth and neurodevelopmental delay
Brain injury in premature infants is of enormous public health importance because of the large number of such infants who survive with serious neurodevelopmental disability”(1)
Of Australian births in 2008
6.1% were low birth weight (LBW,
<2.5kg)
1% were very low birth weight (VLBW,
<1.5kg)
8.2% were preterm (<37 weeks gestation)(2)
While survival rates of VLBW infants have improved,
this has been accompanied by an increase in the number of those survivors who have long term neurological deficits(3)
Preterm birth...
Imaging Findings OR Procedure Details
MRI compatible neonatal incubator
An MRI compatible neonatal incubator (Nomag IC,
Lammers Medical Technology,
Lubeck,
Germany),
with dedicated head and body coils for use with both 1.5T and 3T MRI machines,
has been purchased by the University of Queensland in conjunction with the Royal Brisbane and Women’s Hospital and the Royal Children’s Hospital. This was the first Australian purchase of a device of this type.
The MRIcNI
is suitable for patients with a weight up to approximately 4,500g and a head circumference up to approximately...
Conclusion
The MRIcNI
has improved the safety of MRI for neonates and has contributed to better image quality
is a significant resource for research in preterms,
LBW and term babies with brain injury
is providing better access to imaging for younger,
smaller and sicker infants in the clinical setting
in the future will allow for more advanced imaging techniques to be applied to this vulnerable population
will facilitate translational research that will lead to improved neurodevelopmental outcomes in this vulnerable high risk population
