“…In our study, negative predictive value of 50% was lower than that reported by Ouellette et al [8]. In their study, they found that CSF shuntograms showed abnormalities suggestive of CSF obstruction in 24 patients that required surgery (sensitivity 92%; negative predictive value 93%).…”

Background: Placement of cerebrospinal fluid diversions or shunts, is a common neurosurgical procedure indicated for a wide spectrum of conditions impeding the normal flow of cerebrospinal fluid (CSF). The most common systems employed are ventriculoperitoneal, ventriculoatrial and lumboperitoneal shunts. Management of patients with surgically treated hydrocephalus may be challenging, as the clinical presentation of a malfunctioning shunt is often nonspecific, especially in young children. Moreover, conventional radiological examinations, such as shunt series, cerebral ultrasound or CT scans, are sometimes equivocal in diagnosing cases of shunt malfunction, also in determining the site of obstruction. Thus, numerous procedures have been proposed to ascertain shunt function, and localize site of obstruction. Injection of contrast media and radionuclide directly into the shunt device into the lateral ventricles is one of the most common techniques employed, to assist in evaluating shunt function.

This article presents a description of tele-nuclear medicine and, after outlining its history, a wide, representative range of its applications. Tele-nuclear medicine has benefited greatly from technological progress, which for several decades has provided greater data transfer rates and storage capacity at steadily decreasing cost. Differences in the practice of nuclear medicine between developed and developing countries arise mainly from disparities in their available infrastructure, funding and education levels of personnel involved. Consequently there are different emphases in their tele-nuclear medicine, which are elaborated. It is concluded that tele-nuclear medicine is important for all countries, but the emphasis on its application may differ between developed and developing nations, with an emphasis on distance learning in the latter.

“…The sensitivity, specificity, and accuracy of the radionuclide shuntogram have been described to be as high as 97, 90, and 93%, respectively, in a study by Graham et al [22] that included the analysis of 192 radionuclide CSF shunt studies. In the modern age, the radionuclide CSF shunt study remains a clinically useful and important adjunct diagnostic study to CT and/or MRI for the diagnosis of shunt obstruction or malfunction [21,[23][24][25] .…”

From the early days of pneumoencephalography and ventriculography to the emerging technology of magnetic resonance diffusion tensor imaging (DTI) of the present day, neuroimaging has always been a critical tool in the diagnosis and treatment of pediatric hydrocephalus. There is accumulating evidence from both human and animal research suggesting that one of the major pathophysiological mechanisms underlying poor outcomes in these children is damage to vulnerable white matter (WM) structures in the brain as a result of ventricular enlargement and increased intracranial pressure. However, a clear understanding of these WM abnormalities and their implications on neurobehavioral outcomes in these patients is not well understood. To this end, DTI has recently been studied to allow noninvasive quantification of these abnormalities. Our review discusses the evolution of neuroimaging in pediatric hydrocephalus and focuses on the use of advanced imaging techniques, such as DTI, which is supported by a growing body of literature as a promising noninvasive imaging tool in the diagnosis and long-term management of this patient population. We conclude with a brief discussion on emerging techniques and experimental imaging.
