| Abstract | 「要旨」Hybrid emission CT-HEADTOME IおよびIIを用いて, 対象20例に対してRIシステルノグラフィーを施行し, 臨床的検討を行った. 従来のガンマカメラによるRIシステルノグラフィーでは, はっきりと解像できなかった脳底部各槽, 迂回槽, シルビウス槽等の解剖学的構造が, よく同定できた. またクモ膜下腔閉塞の所見も同様に読影できた. 脳室内逆流現象は, 本法にてきわめて明瞭に判定でき, 少量の逆流でも観察可能であった. 持続性脳室内逆流のみられた6例中4例に, transependymal penetrationが観察された. 正中付近にあるクモ膜嚢胞についても, ガンマカメラによる従来のRIシステルノグラフィーよりも, 本法は有利であった. 「I. はじめに」RIシステルノグラフィーは, 1964年Di Chiro以来, 脳脊髄液(以下CSFと略す)循環の動態検査法として用いられてきた. 使用核種も131I-HSAから111In-DTPAへとよりRIシステルノグラフィーに適した放射性薬剤が開発され, またガンマカメラの解像力向上により画質改善もなされてきた. |

| Abstract | [Summary]Tomographic radionuclide (RN) cisternography was carried out using the single-photon; high-resolution mode of the Headtome in 20 patients with various pathology. These were 9 patients with subarachnoid hemorrhage, 6 with dementia and other 5 patients. The study was performed at 6, 24 and 48 hours after an intra-thecal injections of 1 mCi of 111In-DTPA, conjuncted with the conventional RN cisternography using a γ camera. The X-ray CT was also performed on all the patients. The results of the study were summarized as follows: 1) The tomographic RN cisternography could more clearly visualized than the conventional RN cisternography fine-structural details of subarachnoid spaces, such as the basal cisterns, the ambient cistern and so on. 2) Subarachnoid blocks and an arachnoid cyst at the midline of the brain were clearly revealed by the study. 3) Ventricular reflux of the injected radionuclide was definitely visualized in 11 patients. Among them, 4 of the 6 patients who showed a persistent ventricular-reflux demonstrated the image of transpendymal absorption of the injected RN by the tomography, which would show transependymal absoprtion of the cerebrospinal fluid. |
