False-colour magnetic resonance image (MRI) of the head and normal brain of an 80-year-old man. The face is at right: the profile is not complete as this sagittal section is not perfectly central. The brow crest is seen upper right (black). To its left are the cerebral convolutions of the brain (olive green). At centre (light blue) is brainstem which communicates with the spinal cord. Beside the brainstem (left) is the smaller,convoluted cerebellum. MRI scanning is a valuable diagnostic technique which gives good contrast between normal and abnormal tissues (such as tumours). MRI does not use X-rays or other harmful radiation; instead it uses a strong magnetic field and radio waves | |
