Objective: Flow diverters (FDs) are widely used to treat intracranial aneurysms, with DSA serving as the gold standard for follow-up evaluation. Although a few studies have reported the use of photon-counting detector CTA (PCD-CTA) for minimally invasive follow-up after standalone FD treatment, PCD-CTA after coil-assisted FD placement has never been documented.
Shigematsu et al. (Thu,) studied this question.
