Radiation dose comparison of conventional radiography and photon-counting CT for ventriculoperitoneal shunt imaging: A phantom study

Key Points

• To evaluate the radiation dose and imaging quality of photon-counting CT versus conventional radiography for ventriculoperitoneal shunt assessment.
• Conducted a phantom study comparing radiation doses of both imaging modalities.
• Assessed visualization quality of shunt components using both techniques.
• Measured radiation exposure for each imaging technique.
• Photon-counting CT showed a significant reduction in radiation dose compared to conventional radiography.
• Improved visualization of shunt components was noted with photon-counting CT relative to traditional methods.
