Aquillion prime

Of nine patients who underwent acute-phase thrombectomy at our hospital between November 2018 and June 2019, we simultaneously performed plain CT and DECT for six in whom CT after treatment demonstrated high-density areas, and conducted magnetic resonance imaging (MRI), including T2*-weighted imaging, the following day to examine its association with DECT. For DECT, an Aquillion PRIME (Toshiba, Japan) was used. The following imaging conditions were adopted: dual energy volume scan (two-rotation system); tubal voltage, 80/135 kVp; tubal current, 600/200 mA; collecting detector, 0.5 mm × 80 rows; tube rotation speed, 1 second; rearrangement function, FC13; and rearrangement slice thickness, 5 mm. The authors were responsible for image assessment of the presence of a high-density area on CT after treatment. We confirmed the area of contrast medium on an iodine map obtained using DECT and measured the CT values at several points per area. The greatest value was regarded as the maximum in the area. In our hospital, a direct aspiration first pass technique (ADAPT) with a Penumbra system (Penumbra Alameda, CA, USA) was selected as the first-choice procedure for thrombectomy. When a thrombus was impossible to aspirate, treatment was performed using different stent retrievers based on the conditions in individual patients.
