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.
A magnetic resonance imaging (MRI) scan is a painless procedure that lasts 15 to 90 minutes, depending on the size of the area being scanned and the number of images being taken.
