Radionuclide shuntography
Radionuclide cisternography is a nuclear medicine imaging technique that uses Tc-DTPA (diethyletriaminepentaacetic acid; pentetate) injected into CSF shunt reservoirs to evaluate their patency.
Imaging is performed at 2-6 hours after injection of the radiopharmaceutical into the shunt reservoir. Shuntograms increase the sensitivity of diagnosis of shunt obstruction when used in conjunction with CT compared to CT alone .
