Photon-Counting CT Angiography Successfully Localizes Spinal AV Fistulas

Photon-counting detector CT angiography successfully localized spinal arteriovenous fistulas in all eight patients, with 0.2 mm low-energy threshold reconstructions providing the best visualization. Confirmed at surgery or DSA.

• Retrospective case series of eight patients across two centers.
• Confirmation by surgery or conventional angiography in all cases.
• Small sample size may limit generalizability.
