Acute stroke imaging includes native CT, CT-angiography (CTA), and CT-perfusion (CTP). CTP assesses the irreversibly damaged infarct core (IC), and the potentially salvageable penumbra (PEN) and distinguishes these from areas of healthy parenchyma (HA). However, it requires additional contrast agent and radiation.

We compared both techniques in a retrospective single-center analysis, to investigate whether there are significant differences in the incidence of microemboli depending on the device used.
Materials And Methods: Sixty-two cases treated with Contour were retrospectively compared with 84 WEB cases.
Article Synopsis
- Mechanical thrombectomy using the SOFIA/SOFIA PLUS catheters is being evaluated as a primary treatment for acute ischemic stroke with large vessel occlusion, focusing on its safety and efficacy in a multi-center study involving 246 patients.
- Results show that primary aspiration with the catheters achieved 72.8% complete recanalization and 63.8% of patients were functionally independent after 90 days, with acceptable complication rates.
- The study supports using this technique as a first-line approach in stroke treatment, reinforcing the effectiveness of direct aspiration thrombectomy in managing acute ischemic strokes.
Article Synopsis
- The contour neurovascular system (CNS) is a device used to treat specific types of brain aneurysms, but its metal components interfere with MRI imaging after implantation.
- This study involved creating 3D models of aneurysms and testing different imaging methods, including CTA and MRI, to find effective non-invasive alternatives to the standard digital subtraction angiography (DSA).
- Results showed that focused spectral CTA with metal artifact reduction provided clear imaging similar to DSA, making it a good option for follow-ups, while MRI was limited in assessing critical areas around the aneurysms post-implantation.
Background And Purpose: Mechanical thrombectomy (MT) for acute ischemic stroke (AIS) relies on efficient tracking of aspiration catheters through complex vascular anatomies. Differences in catheter design lead to variation in tracking performance which may only become apparent after use in patients. We developed an methodology for evaluating aspiration catheter performance under a variety of pre-defined circumstances, that can be used during catheter development for design optimization.
