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.
Overview. Magnetic resonance imaging, or MRI, is a method of scanning the human body that provides clear, detailed pictures of organs and soft tissue. A contrast dye is sometimes used to enhance the quality of the scans, although most scans do not need it.The contrast makes it easier to see a tissue that is hard to detect.agnetic resonance imaging, or MRI, is a method of scanning the human body that provides clear, detailed pictures of organs and soft tissue.
