What are the different types of tests to image the brain and spine?
There are many types of tests to image (take a picture of) your child’s brain and spine. These tests can check the shape and parts of the brain and spine. In people with certain genetic conditions, such as Myhre syndrome, there can be differences in these body parts. Some are not a problem while others might be important.
Types of brain and spine imaging tests
|Type of test||What the test does||Radiation||Contrast dye||Important things to know|
|Ultrasonography||Ultrasound can make pictures of the brain and spinal cord. This is most useful in infants.||No||No||
|MRI with angiography (MRA)||
An MRI refers to “magnetic resonance imaging.” This technique uses magnets to image internal organs, including the brain and spinal cord.
Pictures from an MRI are clearer than an ultrasonographic exam.
In order to take a picture of the blood vessels in the brain and spinal cord, we use MRA. Contrast is added to the MRI.
|CT scan with angiography (CTA)||A CTA is a type of X-ray that makes pictures of the heart and blood vessels in the brain and spinal cord.||Yes, but a small, safe dose||Yes||
