Measure: To estimate the cranial capacity of each skull in the Gizmo, measure the area of the part of the cranium that houses the brain. This part of the cranium is roughly behind the red line in the diagram at right.
Chemical dyes are sometimes injected into patients prior to an MRI (magnetic resonance imaging) to enhance internal images. However, certain widely used MRI dyes may cause a number of side effects, including a serious, potentially fatal disease known as nephrogenic systemic fibrosis, or NSF.
Magnetic Resonance Imaging (MRI). An MRI is a large imaging device that sits in its own room. It uses a harmless magnetic field and radio waves to get clear, sharp pictures of the inside of your brain.An MRI is used to detect bleeding in the brain, tumours or stroke. It is also an excellent device for detecting smaller strokes or strokes in the back of the brain, which other imaging devices can miss.MRI images show even more detail than CT scans, and can be viewed in 3-D on a computer screen.agnetic Resonance Imaging (MRI).
