Fig. 3. Sagittal scans of a child with a hypothalamic
glioma. Because the T, value of the tumour is
greater than 800 m.sec. it is poorly seen on the
modified SSFP sequence (a) whereas it is clearly
seen on the standard sequence (b) which embraces
long Ti values. Note the difference in the appear-
ance of the C.S.F. in the two images which is due to
the same cause.

Fig. 5. Transverse scan in a patient with a right
acoustic neuroma. Note the absence of artefact
allowing clear delineation of the brain stem.
Fig. 6. Transverse scan showing an intra-cerebral
haematoma in the right basal ganglia. The central
region of lower density probably represents lique-
faction within the clot.
