Multiple intracranial aneurysms in polyarteritis nodosa: MRI and angiography.

abstract：:From printout data of 50 normal and 50 abnormal scans of a brain slice picking up the basal ganglia the numerical values of SD and DC were obtained and those values lying inside M + 2sigma were arbitrarily regarded as normal. By these criteria two cases (4%) were diagnosed as false negative and three cases (6%) as fal...
