Nineteen hydrocephalic patients were studied to determine factors affecting cerebrospinal fluid (CSF) flow through shunts. This study was based on our previously reported method by which fluctuations in CSF flow through a shunt of from 0.01 ml min-1 to 1.93 ml min-1 were identified, each having its own rhythmic pattern. While CSF flow in a supine position was less than 0.01 ml min-1, head eleva...

We measured the changes in the cerebrospinal fluid (CSF) flow dynamics after compression of the bilateral jugular veins using phase contrast-magnetic resonance imaging (PC-MRI). PC-MRI was performed in 10 healthy male volunteers using a 3T clinical scanner with a two-dimensional gradient echo sequence. We successfully measured the changes in CSF flow velocity using PC-MRI with and without compr...

A hydrodynamic bi-compartmental model for the cerebrospinal fluid (CSF) flow in humans is presented which combines anatomical and physiological conditions in the central nervous system with results of special radioisotope diagnostic techniques. Normal and disturbed conditions, the diagnostic methods and the results are explained. A differential equation for the time behaviour of regional radioi...

BACKGROUND AND PURPOSE PCMR, widely used for the evaluation of blood flow, has been adopted for the assessment of cerebrospinal fluid flow in a variety of disorders. The purpose of this study was to evaluate the accuracy and reproducibility of 2 fast PCMR techniques for measuring CSF flow. MATERIALS AND METHODS Velocities were calculated from RPC and CPC images of fluid flowing in a tube at a...

There is increasing evidence that children suffer from the consequences of spontaneous or iatrogenic intracranial hypotension. Pediatric epidural blood patch is gaining popularity because of its ability to alter cerebrospinal fluid dynamics and to alleviate headaches attributed to low cerebrospinal fluid pressure. There is, however, still not enough data to document the safety profile of an epi...

Background The aim of our study was to evaluate the feasibility of 4D phase contrast (PC) flow imaging for visualisation and analysis of cerebrospinal fluid (CSF) flow in Chiari I malformation. CSF flow was compared between healthy volunteers and patients with Chiari I malformation with and without syringomyelia. Moreover, the effect of a craniocervical decompression on CSF flow was studied in ...

cerebrospinal fluid in both the diagnosis and prognosis ?f various conditions included in the general term meningitis." Since 1912, when Mestrezat1 published his monograph on normal and pathological cerebro-spinal fluids, the value of cytological and chemical investigations lias become firmly established. The literature upon this subject is considerable, but references to the chloride estimatio...

In this paper we analyze volumes of the cerebrospinal fluid spaces for the diagnosis of hydrocephalus, which are served as reference values for future studies. We first present an automatic method to estimate those volumes from a new three-dimensional whole body magnetic resonance imaging sequence. This enables us to statistically analyze the fluid volumes, and to show that the ratio of subarac...

A case of subhepatic cerebrospinal fluid cyst, an uncommon complication of ventriculoperitoneal shunting, is presented. Sonography could not reliably prove shunt tubing to be entering the cystic spaces. Results of computed tomography scanning were definitive.
