Filter by:The investigators retrospectively reviewed all radionuclide shuntographic tests using (99m)technetium-pertechnetate (DTPA) performed between August 2005 and December 2015 in nuclear medicine department of Far Eastern Memorial Hospital. The results of shuntography were evaluated visually and qualitatively, and correlated with clinical follow-up. The tests were interpreted as normal and abnormal, including complete distal obstruction, partial distal obstruction or miscellaneous. Clinical outcomes within 30 days were defined based on subsequent need for revision, re-implantation or adjustment of shunt pressure. Then the investigators calculated the sensitivity (Se), specificity (Sp), positive predictive value (PPV), negative predictive value (NPV) and overall accuracy.
