UNLABELLED: Radionuclide cisternography is an indispensable examination to detect cerebrospinal fluid (CSF) leakage in patients suspected of having spontaneous intracranial hypotension (SIH). However, it sometimes fails to demonstrate the site of CSF leakage, and in such cases, early bladder visualization is utilized for the diagnosis of SIH as an indirect finding. The aim of this work is to improve the diagnostic ability of radionuclide cisternography and to reevaluate the reliability of early bladder visualization as an indirect finding of CSF leakage...

REVIEW
Katalin Borbély
The most common problem addressed by dynamic radionuclide imaging of cerebrospinal fluid (CSF) abnormalities is differentiating patients with normal-pressure hydrocephalus (NPH) from those with other forms of degenerative brain disorder who would clearly not benefit from surgical treatment by ventricular shunting. Radionuclide cisternography (RC) SPECT and regional cerebral blood flow (rCBF) SPECT are critically important for the diagnosis and therapy management of patients with chronic hydrocephalus. However, radionuclide imaging is helpful not only in identifying patients with NPH showing improvement after shunting...

An overview of significant research results of the last four decades as well as the author's own experience have served as a basis for the presentation of the radioisotope method and the radiopharmaceuticals in the diagnostics of normal pressure hydrocephalus (NPH). Also the physiology of the formation of PM-R its flow and absorption have shortly been discussed. Hydrocephalus is a major clinical, diagnostic and therapeutical problem. In the initial diagnosis of that pathology, methods like CT and MRI play an important role, which has also been the subject of this article...

UNLABELLED: AIMS OF THE PRESENT INVESTIGATION: Observations made in a preliminary study of pulsatile cerebrospinal fluid (CSF) and brain motions using MR imaging called for a reconsideration of the CSF flow model currently accepted. The following questions were addressed: 1) The nature of the CSF-circulation, e.g., the magnitude and pattern of pulsatile and bulk flow; 2) The driving forces of the CSF circulation and assessment of the role of associated hemodynamics and brain motions; 3) The major routes for the absorption of CSF...

W J Shih, E Tasdemiroglu
A man with dementia underwent radionuclide cisternography to establish the diagnosis of communicating hydrocephalus. Technetium-99m-HMPAO brain SPECT images showed marked hypoperfusion of both posterior cerebral cortices and three-dimensional displays that demonstrated perfusion defects at both of the posterior parietotemporal regions. A successful ventriculoperitoneal shunt operation was performed. Five and one-half months later, repeat three-dimensional display showed that the perfusion defects had resolved and a repeat brain SPECT image showed marked improvement of the hypoperfusion...

As cerebrospinal fluid (CSF) shunts function for several years, outgrowth and disconnection of the distal catheter are seen more frequently. Though a shunt revision is clearly indicated if patients are symptomatic, asymptomatic patients with a disconnection or who have outgrown the distal catheter may no longer require CSF diversion. This follows an assumption that the shunt is no longer functioning and, in an asymptomatic patient, no longer required. However, patent fibrous tracts have been postulated which may allow passage of CSF through disconnected or outgrown distal catheters...

COMPARATIVE STUDY
B C Berg
For 6 consecutive months all triage acceptable emergency room patients at the St. Francis Medical Center with blunt or penetrating trauma involving the abdomen were included in this review. Computed tomography and radionuclide imaging of the abdomen and urinary tract was performed in addition to the usually indicated diagnostic procedures. In our hospital the Radiology Department is adjacent to the Emergency Department. Close cooperation of the trauma team, the imaging physician and the technologists, has provided a stable, reproducible pattern in the performance and evaluation of nuclear medicine and radiographic techniques...

Cerebrospinal fluid dynamics were studied in eight dogs during normal, hydrocephalic, and postoperative phases. Radionuclide-labeled substances introduced into the normal ventricular system flow out of the exits from the fourth ventricle to the convexity subarachnoid spaces superiorly to be absorbed in the sagittal sinus, and basorostrally to the exits from the perineural olfactory sheath into the nose to produce physiological cerebrospinal fluid (CSF) rhinorrhea. Serial radionuclide ventriculography of the head following intraventricular isotope injection of labeled proteins and chelate into the kaolin-induced hydrocephalic system shows a high degree of ventricular stasis with no perineural olfactory nerve flow (rhinorrhea)...

REVIEW
E B Silberstein
Computed transaxial tomography (CTT) has become the major imaging tool in the evaluation of any intracerebral lesion, including those due to traumatic injury. Expense and availability sometimes dictate that radionuclide brain scintigraphy (RBS) be performed in place of CTT. Certain situations exist where RBS may be used as a primary tool. These include circumstances where assessment of brain perfusion may be essential, e.g., determination of brain death. Radionuclide cisternography still remains useful in evaluating patients with normal pressure hydrocephalus and cerebrospinal fluid leakage...
