Photon-Counting Detector vs. Energy-Integrating Detector CT Myelography for Detecting CSF-Venous Fistulas in Spontaneous Intracranial Hypotension: Substantially Lower Radiation Dose

Key Points

• Evaluate the effectiveness and safety of photon-counting detector CT myelography compared to energy-integrating detector for detecting CSF-venous fistulas.
• Analyzed CT myelography sessions using photon-counting and energy-integrating detectors.
• Compared radiation doses between the two types of detector.
• Assessed anatomic coverage and number of acquisitions during procedures.
• Photon-counting detector CT myelography resulted in approximately 65% lower radiation dose than energy-integrating detector.
• Examined a longer anatomic range without increasing radiation exposure.
