Statistical Evaluation of Cerebrospinal Fluid Circulation by Radioisotope Cisternography Using SPECT Method: A clinical study
This study is designed to obtain more reliable diagnosis of an impairment of cerebrospinal fluid (CSF) circulation in patients with suspected of hydrocephalus or malfunctions of shunt systems. Such seventeen patients and three control patients (pituitary adenoma; 2, suspected CSF rhinorreal; 1) were included in our study. Twelve male and eight female patients ranged from 18 to 70 year-old (mean 59.5, postoperative follow-up period after a final diagnosis; 2–32 months). Etiologies of the diseases were subarachnoid hemorrhage (4), brain tumor (2), unknown (10), and cryptococcal meningitis(1).
