Decide confidently “to treat” or “not to treat” complex AVMs


Your ability to visualize the extremely complex pathologies of arteriovenous malformations (AVMs), fistula and other malformations is crucial in deciding whether to treat or monitor a patient. For decades, neuro specialists have relied on Philips sophisticated neuro imaging solutions to support confident planning and treatment decisions for AVM interventions. Now, as the field shifts towards medical monitoring of unruptured AVMs, the tools we offer can once again support you in making a difference in the lives of your patients.

SmartCT Soft Tissue on FlexVision


SmartCT enriches our outstanding 3D interventional tools with step by step guidance, designed to remove barriers to acquiring 3D images in the interventional lab. It simplifies 3D acquisition to empower clinical users* to easily perform 3D imaging.5 Once acquired, 3D images are automatically displayed within seconds** on the touch screen module in the corresponding rendering mode. On the same touch screen, the user can easily control and interact with advanced 3D visualization and measurement tools.

    Clinical solutions for monitoring and treating AVMs

    3DRA AVM

    3D visualization of heterogeneous vasculature


    SmartCT Angio provides a volumetric view in a few seconds2 to assist assessment of feeding arteries, draining veins, arterialized veins, nidus and ruptured or unruptured pathology to guide decision making. 3D volumes are visualized with high spatial resolution and automatic patient movement compensation to enhance visibility of critical details.

    Enhance imaging of vessels and devices in the brain

    SmartCT Vaso

    SmartCT Vaso provides high resolution 3D imaging that reveals key information about cerebral vascular structures to support the highest possible spatial assessment of vessels in the soft tissue context.

    Navigate confidently through complex vessel structures

    Navigate complex vessel structures

    SmartCT Roadmap overlays a 3D reconstruction of the vessel tree, vessel segments or annotations, acquired with a SmartCT acquisition mode on your Philips interventional X-ray system, with live fluoro images. It provides a full 3D view for guidewire and catheter navigation through complex vessel structures.

    Differentiate between glue and subtraction error

    glue and subtraction error

    When you are monitoring AVMs over time, subtraction artifacts can disguise clinical information. Philips’ unique ClarityIQ automatic pixel shift helps remove information that may be misleading, in real-time and without user interaction.

    Identify direction and arrival of liquid embolic agent

    Lesion boundaries CT Roadmap

    During treatment, subtraction artifacts can obscure the direction liquid embolic agents are traveling. Using the automatic pixel shift in our ClarityIQ enables you to visualize the direction the liquid embolic agent is traveling and its arrival.

    Clearly visualize newly injected liquid embolic agent

    Roadmap Pro Neuro

    The Roadmap Pro glue mode filters out already embolized vessels, allowing you to focus on what you are injecting and how it is diffusing.

    Check final result and potential bleedings

    Cerebral Aneurysm

    SmartCT Soft Tissue is an acquisition technique that generates a CT-like visualization of soft tissue in relation to other structures during procedures. You can use the CT-like images to assess soft tissue after an AVM to check the final result and potential bleedings when the patient is still on the table.

    Workflow innovations to treat AVMs

    Azurion offers a number of workflow innovations designed to help staff work efficiently and easily, while maintaining a single-minded focus on the patient and managing radiation dose during AVM interventions.

    Azurion Biplane B20/12

    Sharp, motion-free vessels at low dose

    ClarityIQ wheel

    ClarityIQ provides high quality imaging for a comprehensive range of clinical procedures, achieving excellent visibility at low X-ray dose levels.  In interventional neuro procedures, ClarityIQ technology reduces patient dose by 65% for the total procedure without affecting the procedural performance, compared to an Allura Xper system.1

    Manage dose and simplify workflow

    Zero Dose Positioning

    Zero Dose Positioning helps you reduce dose by allowing you to pan the table, change table height or move the X-ray system on Last Image Hold to determine the new center position. This helps you prepare your next run without using fluoroscopy.

    Full table side control within sterile field

    FlexVision Pro

    Gives you direct access and full control of pre-operative diagnostic scans, patient information and planning tools at table side to save time and unnecessary walking in and out of the sterile area.

    Reduce in-lab prep time supported by ProcedureCards

    ProcedureCards image

    ProcedureCards streamline and standardize system set-up and help reduce preparation errors. Select the AVM ProcedureCard and the system is set-up the way you want. Hospital specific aneurysm protocols and/or checklists can be added to ProcedureCards and displayed on monitors. One hospital reduced in-lab prep time supported by ProcedureCards.4

    Use neuro headrest to help reduce motion artifacts

    Neuro headrest

    Can be used to restrain restless patients under conscious sedation to help reduce motion artifacts during the procedure.

    1.  In routine neuro endovascular procedures*, the AlluraClarity system with ClarityIQ technology may reduce patient dose (as dose-area product) by as much as 62% (in routine diagnostic neuro endovascular procedures) and as much as 65% (in routine interventional neuro endovascular procedures)** for the total procedure without affecting the procedural performance (fluoroscopy time and number of DSA images) as compared to equivalent procedures on an Allura Xper system, as demonstrated in one single-center study.*** 

      *Routine neuro interventions comprise of DSA and fluoroscopy usage. ** (95% CI 56%, 68% for routine diagnostic neuro endovascular procedures, 95% CI 58%, 71% for routine interventional neuro endovascular procedures). The results of the application of dose reduction techniques will vary depending on the clinical task, patient size, anatomical location and clinical practice. The interventional radiologist assisted by a physicist as necessary has to determine the appropriate settings for each specific clinical task. *** Results based on total dose area product from a single center retrospective historically controlled cohort study (Karolinska Hospital - Solna, Sweden) on 614 patients (302 for Allura Xper and 312 for AlluraClarity) undergoing neuro endovascular procedures.
