to assess tissue changes responsible for enhancement of the meninges adjacent to meningiomas on magnetic resonance ( mr ) images , the authors correlated the mr imaging characteristics of meningeal lesions seen before and after administration of gadolinium diethylenetriamine-pentaacetic acid ( dtpa ) with the appearance of these lesions on contrast material-enhanced computed tomographic ( ct ) images and with histopathologic findings in four patients .
