Diagnosis & Imaging
Magnetic resonance imaging (MRI)
MRI is a detailed imaging method using magnetic fields to show the brain and soft tissues without radiation.
In short: Magnetic resonance imaging (MRI)
- It is excellent for examining the brain and the sac contents.
- It does not use radiation.
- It is used before and after birth.
- It complements CT, which shows bone well.
What it is
It is an imaging method that uses magnetic fields and radio waves to create detailed pictures of the brain and other soft tissues. It does not use ionizing radiation.
Understanding Magnetic resonance imaging (MRI)
MRI is excellent for examining the brain and the contents of an encephalocele sac, distinguishing membranes and fluid from brain tissue and revealing associated brain findings. It is used both before birth (fetal MRI) and after, and it complements CT — which is better for showing bone and the bony defect. Because it shows soft tissue in such detail, MRI is central to assessing the brain in encephalocele.
Why it matters
Understanding MRI helps families see why it is the key test for examining the brain and the sac contents, and how it works together with CT to give a complete picture of soft tissue and bone.
Common questions
What is MRI good for?
Examining the brain and soft tissues, including the sac contents.
Does it use radiation?
No.
How does it differ from CT?
MRI shows soft tissue; CT shows bone well.
Bottom line
MRI uses magnetic fields to image the brain and soft tissues in detail, without radiation.
