PC CT technology offers enhanced visualization capabilities, especially for small structures, and opens up new possibilities for detailed three-dimensional imaging. Shunt valves are implanted under the skin and redirect excess cerebrospinal fluid, for example, to the abdominal cavity through a catheter. They play a vital role in regulating cerebrospinal fluid drainage in various pathologies, which can lead to hydrocephalus. Accurate imaging of shunt valves is essential to assess the rate of drainage, as their precise adjustment is a requirement for optimal patient care. This study focused on two adjustable shunt valves, the proGAV 2.0\u00ae and M. blue\u00ae (manufactured by Miethke, Potsdam, Germany). A comprehensive comparative analysis of PC CT and traditional X-ray techniques was conducted to explore this cutting-edge technology and it demonstrated that routine PC CT can efficiently assess shunt valves\u2019 adjustments. This technology shows promise in enhancing the accurate management of shunt valves used in settings where head scans are already frequently required, such as in the treatment of hydrocephalus.<\/jats:p>","DOI":"10.3390\/tomography10040043","type":"journal-article","created":{"date-parts":[[2024,4,12]],"date-time":"2024-04-12T04:44:26Z","timestamp":1712897066000},"page":"543-553","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Three-Dimensional Visualization of Shunt Valves with Photon Counting CT and Comparison to Traditional X-ray in a Simple Phantom Model"],"prefix":"10.3390","volume":"10","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5633-741X","authenticated-orcid":false,"given":"Anna","family":"Klempka","sequence":"first","affiliation":[{"name":"Department of Neuroradiology, University Medical Centre Mannheim, Medical Faculty Mannheim, University of Heidelberg, 68167 Mannheim, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0224-348X","authenticated-orcid":false,"given":"Sven","family":"Clausen","sequence":"additional","affiliation":[{"name":"Department of Radiation Oncology, University Medical Centre Mannheim, Medical Faculty Mannheim, University of Heidelberg, 68167 Mannheim, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0007-3642-527X","authenticated-orcid":false,"given":"Mohamed Ilyes","family":"Soltane","sequence":"additional","affiliation":[{"name":"Department of Neuroradiology, University Medical Centre Mannheim, Medical Faculty Mannheim, University of Heidelberg, 68167 Mannheim, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0009-3319-1855","authenticated-orcid":false,"given":"Eduardo","family":"Ackermann","sequence":"additional","affiliation":[{"name":"Department of Neuroradiology, University Medical Centre Mannheim, Medical Faculty Mannheim, University of Heidelberg, 68167 Mannheim, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9078-5539","authenticated-orcid":false,"given":"Christoph","family":"Groden","sequence":"additional","affiliation":[{"name":"Department of Neuroradiology, University Medical Centre Mannheim, Medical Faculty Mannheim, University of Heidelberg, 68167 Mannheim, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2024,4,12]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"147","DOI":"10.1016\/j.wneu.2022.08.154","article-title":"The Birmingham Standardized Idiopathic Intracranial Hypertension Shunt Protocol: Technical Note","volume":"167","author":"Tsermoulas","year":"2022","journal-title":"World Neurosurg."},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"2605","DOI":"10.1007\/s00381-021-05162-3","article-title":"Efficacy and safety of the Miethke programmable differential pressure valve (proGAV\u00ae2.0): A single-centre retrospective analysis","volume":"37","author":"Hall","year":"2021","journal-title":"Childs Nerv.
