Multimodal radionuclide shuntography for device patency: New procedural tips for anuncommon historical technique.
Cerebrospinal fluid (CSF) shunting is an established long-term treatment option for hydrocephalus, and is one of the most commonly performed neurosurgical procedures in western countries.Despite advances in CSF shunt design and management, its failure rates remain high and is most commonly due to obstruction and infection.Cerebrospinal fluidshunt failure diagnosis should be prompt and accurate in establishing timely if its revision is appropriate. Radionuclide shuntography with technetium-99m-diethylenetriaminepetaacetic acid (99mTc-DTPA) is a useful technique for evaluation CSF shunts and management of patients presenting with shunt-related problems, in particular it can avoid unnecessary replacement interventions. Although its execution and interpretation require specific skills, we suggest its execution for the evaluation of device's patency. We here describe the radionuclide shuntography performed with recent hybrid multimodal technologies, with a procedure customized to a complicated patient with hydrocefalus and neoplastic disease. We suggest considering radionuclide shuntography in association with conventional imagingand strongly recommend the additional performance of single photon emission computed tomography/computed tomography (SPECT/CT) because it also provides valuable information to complete the interpretation of planar images.
期刊介绍:
The Hellenic Journal of Nuclear Medicine published by the Hellenic Society of
Nuclear Medicine in Thessaloniki, aims to contribute to research, to education and
cover the scientific and professional interests of physicians, in the field of nuclear
medicine and in medicine in general. The journal may publish papers of nuclear
medicine and also papers that refer to related subjects as dosimetry, computer science,
targeting of gene expression, radioimmunoassay, radiation protection, biology, cell
trafficking, related historical brief reviews and other related subjects. Original papers
are preferred. The journal may after special agreement publish supplements covering
important subjects, dully reviewed and subscripted separately.
