There were 118 false-negative results in a series of 847 cases of proved intracranial lesions subjected to brain scanning. In patients with neoplasms false-negative results are much more likely if the site of the tumour is infratentorial or mediobasal. In patients with stroke the incidence of false-negative results depends on the stroke-scan interval.
