The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) IF: 0.6 The Immediacy Index is the average number of times an article is cited in the year it is published. The journal Immediacy Index indicates how quickly articles in a journal are cited. Immediacy Index: 0.6 The Eigenfactor score, developed by Jevin West and Carl Bergstrom at the University of Washington, is a rating of the total importance of a scientific journal. Journals are rated according to the number of incoming citations, with citations from highly ranked journals weighted to make a larger contribution to the eigenfactor than those from poorly ranked journals. Eigenfactor: 0.00013 The Journal Citation Indicator (JCI) is a single measurement of the field-normalized citation impact of journals in the Web of Science Core Collection across disciplines. The key words here are that the metric is normalized and cross-disciplinary. JCI: 0.14 SJR: 0.201 SNIP: 0.313 CiteScore™:: 1.2 H-Index: 13

ABSTRAKT

In order to characterize the flow of Cerebral Spinal Fluid (CSF) within the third ventricle and cerebral aqueduct of a healthy adult, an in vitro steady flow loop is developed. Rapid Prototyping (RP) technology is used to create a geometrically realistic ventricular model. Particle Image Velocimetry (PIV) is used to obtain 2D velocity vector maps of the flow in the mid-sagittal plane of the model for the cranio-caudal as well as caudo-cranial flow directions. CSF steady flow rates used correspond to the physiological flow rate range. The PIV results demonstrate that the highest velocities occur in the mid-aqueduct region of the test section and the lowest velocities occur in a dead zone located in the antero-inferior region of the third ventricle. In the case of cranio-caudal flow, the results show a relatively small recirculation region located adjacent to a downward jet resulting from the influx of CSF from the Foramen of Monro. The results of this study have implications with respect to pathophysiology of hydrocephalus, mechanisms of CSF diversion in shunt surgery and Endoscopic Third Ventriculostomy (ETV), targeted drug delivery via CSF, and verification of CFD models of CSF flow.
