Comparison shows lower radiation dose with photon-counting detector in CT myelography for CSF-venous fistulas, suggesting improved safety.
In patients undergoing CT myelography for CVF evaluation, PCD-CTM was associated with an approximately 65% lower session-level radiation dose than EID-CTM, despite covering a longer anatomic range and more acquisitions.
