Abstract
Three-dimensional constructive interference in steady state (3D CISS) is a steady-state gradient-echo sequence in magnetic resonance imaging (MRI) that has been used in an increasing number of applications in the study of brain disease in recent years. Owing to the very high spatial resolution, the strong hyperintensity of the cerebrospinal fluid signal and the high contrast-to-noise ratio, 3D CISS can be employed in a wide range of scenarios, ranging from the traditional study of cranial nerves, the ventricular system, the subarachnoid cisterns and related pathology to more recently discussed applications, such as the fundamental role it can assume in the setting of acute ischemic stroke, vascular malformations, infections and several brain tumors. In this review, after briefly summarizing its fundamental physical principles, we examine in detail the various applications of 3D CISS in brain imaging, providing numerous representative cases, so as to help radiologists improve its use in imaging protocols in daily clinical practice.

Melo JRT, Passos RK, Carvalho MLCMD. Cerebrospinal fluid drainage options for posthemorrhagic hydrocephalus in premature neonates. ARQUIVOS DE NEURO-PSIQUIATRIA 2017; 75:433-438. [PMID: 28746429 DOI: 10.1590/0004-282x20170060] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/20/2016] [Accepted: 03/14/2017] [Indexed: 11/22/2022]
Abstract
Objective The literature describes various cerebrospinal fluid (CSF) drainage techniques to alleviate posthemorrhagic hydrocephalus in preterm newborns; however, consensus has not been reached. The scope of this study was describing a case series of premature neonates with posthemorrhagic hydrocephalus and assessing the outcomes of different approaches used for CSF diversion. Methods A consecutive review of the medical records of neonates with posthemorrhagic hydrocephalus treated with CSF drainage was conducted. Results Forty premature neonates were included. Serial lumbar puncture, ventriculosubgaleal shunt, and ventriculoperitoneal shunt were the treatments of choice in 25%, 37.5% and 37.5% of the cases, respectively. Conclusion Cerebrospinal fluid diversion should be tailored to each case with preference given to temporary CSF drainage in neonates with lower age and lower birth-weight, while the permanent ventriculoperitoneal shunt should be considered in healthier, higher birth-weight neonates born closer to term.

Abstract
PURPOSE To evaluate the performance of MR virtual endoscopy (MRVE) in children with hydrocephalus. MATERIALS AND METHODS Clinical and imaging data were collected from 15 pediatric patients with hydrocephalus and 15 normal control children. All hydrocephalus patients were confirmed by ventriculoscopy or CT imaging. The cranial 3D-T1 weighted imaging data from fast spoiled gradient echo scan (FSPGR) were transported to working station. VE images of cerebral ventricular cavity were constructed with Navigator software. RESULTS Cerebral ventricular MRVE can achieve similar results as ventriculoscopy in demonstrating the morphology of ventricular wall or intracavity lesion. In addition, MRVE can observe the lesion from distal end of obstruction, as well as other areas that are inaccessible to ventriculoscopy. MRVE can also reveal the pathological change of ventricular inner wall surface, and help determine patency of the cerebral aqueduct and fourth ventricle outlet. CONCLUSION MR virtual endoscopy provides a non-invasive diagnostic modality that can be used as a supplemental approach to ventriculoscopy. However, its sensitivity and specificity need to be determined in the large study.
