用乳胶囊制成脑积水和脑室囊虫病的模型，行Ｉｓｏｖｉｓｔ造影ＣＴ扫描。结果：造影剂浓度（Ｖ／Ｖ）０．５％～１％时，ＣＴ值６５．１～１２８．３Ｈｕ，造影效果良好，浓度过小，对比度不足，效果不佳，浓度过高，将有较多伪影，可淹没或掩盖病变。以０．５％～１％Ｉｓｏｖｉｓｔ脑室造影ＣＴ扫描４４例，４３例得到明确诊断，造影效果良好，其中交通性脑积水２例，室间孔粘连１例，导水管狭窄２例，正中孔粘连５例，脑室囊虫病３３例，经手术和病理证实诊断符合率为１００％。１例注入造影剂后距扫描时间过短，造影剂尚未扩散到病变部位而失败。
A model of hydrocephalus and ventriculo-cysticercosis was made with a latex capsule and an Isovist contrast CT scan was performed. Results: Contrast agent concentration (V / V) 0.5% ~ 1%, CT value 65.1 ~ 128.3Hu, good contrast effect, the concentration is too small, the contrast is not enough, the effect is not good, the concentration is too high, there will be More artifacts can be submerged or cover up the lesion. 44 cases were diagnosed by Isovist ventriculography 0.5% ~ 1%, 43 cases were diagnosed with good angiographic results, including 2 cases of traffic hydrocephalus, 1 case of intergranular adhesions, 2 cases of stenosis, Adhesion in 5 cases, 33 cases of cerebral cysticercosis, confirmed by surgery and pathology consistent with the rate of 100%. 1 case of injection of contrast agent from the scan time is too short, the contrast agent has not yet spread to the lesion site failure.
