Abstract
A young patient with progressive neurological deficit of uncertain cause underwent true three-dimensional nuclear magnetic resonance (NMR) imaging by the inversion-recovery and by the saturation-recovery techniques. Differences between the results of the two methods helped clarify the nature of the underlying disorder and revealed an extent of neoplasia greatly exceeding that suggested by X-ray computed tomography. The NMR imaging results were instrumental in selecting the site for brain biopsy, which demonstrated a Grade II astrocytoma.
