Figure 2. T2 maps of the temporal lobes showing the sampling area, and histograms of the T2 times with derived average values. The left temporal lobe shows an increased T2 time (123 ms), consistent with mesial sclerosis.
Figure 3. CT of a child with tuberous sclerosis showing periventricular calcification and low attenuation parenchymal tubers. CT remains the imaging modality of choice for identifying focal calcification.
Figure 4. 99Tcm-labelled hexamethyl propyleneamine oxime SPECT interictal brain images. The top two rows show a normal dataset, the bottom two rows show a number of focal defects, especially in the right frontal region.
Figure 8. Coronal T1 weighted MR image through the pituitary region showing the hypothalamic hamartoma responsible for the child's gelastic seizures (arrow).
Figure 10. Cerebral spinal fluid suppression (fluid attenuated inversion recovery (FLAIR)) MR image of the brain of a child with tuberous sclerosis showing multiple cortical tubers and subependymal nodules and a calcified focus in the right occipital lobe. Note the generalized increase in signal intensity of the right cerebral hemisphere related to a recent period of status epilepticus.
Figure 11. (a) CT in the early stages of herpes encephalitis showing reduced attenuation in the right temporal lobe. (b) MR image showing bilateral changes involving the temporal lobes and right cingulate gyrus.
Figure 14. Diffuse axonal injury. Cerebral spinal fluid suppression sequence showing a small area of parieto-occipital gliosis (arrow) following head injury in a child with post-traumatic seizures.
