Interventional Radiology for Hemorrhagic Stroke
For Effective Stroke Therapy
In hemorrhagic stroke, interventional radiological treatment such as coiling has established itself as a standard procedure for treating aneurysms. Moreover, in some cases of arteriovenous malformations (AVM), interventional embolization may be a treatment option as well. Excellent imaging during intervention is indispensable for safe and efficient vascular therapy. Interventional radiology suites should therefore reflect the therapeutic requirements of the interventional imaging technique and the skills of the interventional team.
A comprehensive case presentation relying on access to and integration of data from a variety of imaging modalities are very beneficial for workplaces in interventional radiology. This emphasizes the importance of dedicated software applications, smooth data exchange between diagnostic and interventional radiology, and, in general, efficient data handling in the clinical IT network.
Interventional Imaging in Hemorrhagic Stroke
Interventional angiography systems have to provide uncompromising image quality while interfering as little as possible with interventional procedures.
Siemens Artis Q/ Artis zee family fulfill these requirements by offering comprehensive imaging capabilities complemented by precise and flexible positioning control. It integrates your interventional angiography system into your IT network and thus helps you to monitor the success of treatment.
Angiography is the gold standard¹ to depict aneurysms and visualize and control the placement of coils.
syngo Neuro Aneurysm Analysis (incl. Virtual Stent) facilitates fast and easy evaluation of aneurysms, including overlay of a virtual stent, for easy device implantation.
Siemens syngo® iFlow helps you in verifying whether the aneurysm has been successfully sealed off by providing the possibility to display the inflow and outflow of an aneurysm before and after treatment (coiling or placing of a flow diverter), as well as for embolization of arteriovenous malformations. During the intervention, syngo iPilot (3D-RDMP) helps you guiding the device and controlling stent placement. After the intervention, syngo® iFlow enables you to visualize if the intended modification in blood flow has been achieved.
syngo® DynaCT and DynaPBV Neuro
syngo® DynaCT imaging software provides CT-like data acquisition and visualization for angiography or perfusion analysis in less than a minute (in 512 default reconstruction size). For stroke patients, visualization of brain perfusion is of special importance before, during, and after neuroradiological interventions. Based on DynaCT, Siemens’ syngo® DynaPBV Neuro software allows for an immediate and profound evaluation of the therapeutic success right at the site of intervention. After the intervention, based on syngo® DynaCT, syngo® DynaPBV Neuro permits you to verify that adjacent normal vessels have not been occluded by device placement and that blood volume in the related areas of the brain is normal. This edge-of-technology neuro-imaging software allows for differentiated stroke diagnosis right at the angio suite. Monitoring brain parenchymal blood volume (PBV) and perfusion imaging of the entire brain at the site of intervention saves critical time, avoids patient transportation, and possibly reduces radiation exposure
syngo.plaza and syngo.share
Information systems bring together patient data (images, results of blood investigations etc.) and help to provide a fast overview of a patient`s history. This is essential for the planning of interventional stroke treatment, as well as for the conduction, evaluation and documentation of the intervention.
syngo.plaza provides you with easy and concurrent access to 2D, 3D, and 4D² images at a single workplace, as well as extended functionality for displaying and processing DICOM XA images, allowing DSA viewing directly at the PACS.
syngo.share³ offers you access to clinical information and provides a complete picture of the available images, reports, multi-media, and non-DICOM data from a patient.
