BACKGROUND: Flat-detector computed tomography (FDCT) is increasingly used for periinterventional cerebral imaging. The recently introduced Sine Spin FDCT (S-FDCT) aims to improve cerebral soft tissue contrast compared with conventional FDCT (C-FDCT). Reliable visualization of healthy brain parenchyma is essential for detecting pathological changes. This study compared gray-white matter differentiation between intraindividually acquired S-FDCT and C-FDCT.
METHODS: A retrospective analysis of a prospectively maintained database included patients with ischemic stroke treated by mechanical thrombectomy who underwent both S-FDCT and C-FDCT within the same interventional session on a latest-generation angiography system. Quantitative image quality was assessed using the contrast-to-noise ratio (CNR). Qualitative image quality was evaluated using a five-point scale at basal ganglia and supratentorial cortex. Analyses focused on healthy brain parenchyma contralateral to infarction. Radiation dose was assessed using entrance-skin dose and dose-area product (DAP).
RESULTS: Forty patients (74.2 ± 15.3 years) were analyzed. S-FDCT demonstrated a higher CNR than C-FDCT (mean CNR ± SD: 2.62 ± 1.36 versus 1.03 ± 0.38; p < 0.001). Qualitative ratings were higher for S-FDCT at the basal ganglia (2.45 ± 0.71 versus 1.54 ± 0.53; p < 0.001) and supratentorial cortex (3.01 ± 0.80 versus 1.71 ± 0.60; p < 0.001). Inter-reader agreement was good (κ = 0.798). S-FDCT showed a moderately higher radiation dose than C-FDCT (DAP: 50.6 ± 3.10 versus 46.89 ± 2.86 Gy·cm², p < 0.001).
CONCLUSION: S-FDCT improves cerebral soft tissue visualization compared with C-FDCT in periinterventional imaging. These findings highlight the potential of Sine Spin technology to enhance FDCT image quality and support its role in advanced angiography-suite-based neuroimaging.
