BACKGROUND AND PURPOSE CT myelography has historically been the test of choice for localization of CSF fistula in patients with spontaneous intracranial hypotension. This study evaluates the additional benefits of intrathecal gadolinium MR myelography in the detection of CSF leak. MATERIALS AND METHODS We performed a retrospective review of patients with spontaneous intracranial hypotension w...

INTRODUCTION Occurrence of anastomotic leaks following Roux-en-Y gastric bypass (RYGB), arising principally from the gastro-jejunal anastomosis, is associated with significant morbidity and mortality. Their early detection and treatment is essential. However, a significant number of postoperative oral contrast studies fail to identify leaks, and a negative study providing false reassurance can ...

Gas leak detection is an important issue in infrastructure monitoring and industrial production. In this context, infrared (IR) absorption spectroscopy is a major measurement method. It can be applied in an extractive or remote detection scheme. Tunable laser spectroscopy (TLS) instruments are able to detect CH₄ leaks with column densities below 10 ppm·m from a distance of 30 m in less than a s...

Monitorovanie a únik testovanej WWER – 440 látky namočenej do vyčerpaného paliva zo skladu sústredenom na Slovensku An accelerated monitoring system designed for the Slovak wet interim spent fuel storage facility in NPP Jaslovské Bohunice bases on the newly designed “cesium detectors” is presented in the paper. Since 1999, leak tests of WWER-440 fuel assemblies are provided by a special leak ti...

Pipelines are essential parts of the infrastructure of modern society; Leak detection systems (LDS) are used to protect the public and the environment from the effects of pipeline failure as well as bringing down operational costs, LDS do this by alerting when a leak occur and solving the problems of leakages most often involves the application of two or more methods which largely depends on se...
