采用量化 PET/MR 系统实现个性化成像的新时代

当我们在全面集成的PET/MR系统中引入飞行时间成像技术 (TOF技术) 时,我们说过,这将是一项革命性的创举。我们兑现了这一承诺,现在我们正进一步前行。

配有QuantWorks的SIGNA™ PET/MR成像系统,采用TOF 技术制造并与3.0T MR集成,其引人瞩目的量化准确度和高计数率与创新型Q.Clear重塑功能相结合,将图像质量提高了 2 倍。此外,配有QuantWorks 的 SIGNA PET/MR系统还包括全套应用程序和灵活多样的研究工具,用以探索可能影响未来医学的奇思妙想。

配备 QuantWorks 的 SIGNA PET/MR成像系统并非所有地区均有销售。

充分发挥

高灵敏度和TOF技术的诊断潜力

配有 QuantWorks 的 SIGNA PET/MR成像系统,采用GE专有的硅光电倍增(SiPM)检测器和灵敏度极高的25 毫米深镥基晶体制成。从而得到全面集成的PET/MR系统,具有高灵敏度和TOF成像功能。

此外,我们的创新型Q.Clear重塑功能还利用了TOF技术提供的出色信噪比(SNR)。通过机头的无电离辐射 MR装置,我们的零回波时间(ZTE)MR系统取代了基于X射线的衰减校正方式。图像质量和量化准确度的同步改进,使您能充分发挥 PET/MR系统的潜力。

  • BodyWorks

    With BodyWorks, we address one of the fastest growing areas in MR. This all-inclusive library allows you to image abdominal and pelvic anatomy with user flexibility to adapt to different patient types.

    Auto Navigator is GE's solution to combat respiratory motion in abdominal imaging. This free-breathing approach is compatible with multiple pulse sequences including diffusion, PROPELLER MB, MRCP and dynamic T1 imaging.
  • CVWorks

    With our intuitive cardiac techniques, you can assess morphology, flow, function and tissue viability plus gain crucial insights into vascular structure and flow dynamics. CVWorks provides the flexibility to adapt to different patient types with exams that vastly simplify workflow.

    With CVWorks, multi breath-hold imaging can be a thing of the past. Our latest Single shot MDE and Black Blood techniques provide patient-friendly alternatives to uncomfortable breath-holds.

    With our workflow-simplified QuickStep protocols, scanning whole body vasculature can be done in less than 6 minutes. High performance gradients allow bright blood pool and myocardial tissue contrast on Cine FIESTA while preserving spatial resolution.
  • NeuroWorks

    This one-stop solution enables you to imagine brain, spine, vascular and peripheral nerve anatomy with exceptional tissue contrast. These motion-insensitive techniques feature single-click auto alignment, providing the complete neuro solution from scanning to post processing.

    NeuroWorks also includes Cube, our 3D volumetric imaging suite, standard with every system. This application allows you to suppress CSF and either white or gray matter to increase lesion conspicuity.

    PROPELLER MB, our latest PROPELLER enhancement, is a multi-shot approach that preserves tissue contrast regardless of weighting while also reducing motion artifacts. Additionally, this new technique introduces new contrasts such as T1 FSE.
  • OncoWorks

    This extensive library of techniques captures anatomic and morphologic data to uniquely enable oncological assessment of anatomy. OncoWorks includes robust tissue contrast, motion-insensitive, high temporal and spatial resolution imaging.

    3D volumetric imaging with an optimized adiabatic fat suppression, combined with ARC or ASSET, provides high spatial and temporal resolution to capture contrast uptake patterns. The FSPGR Ax Dynamic image shows lesion characteristics generated using AW VS7's positive enhancement map. The T2 PROPELLER image demonstrates small FOV and motion-correction through the prostate.
  • OrthoWorks

    This one-stop solution enables you to image brain, spine, vascular and peripheral nerve anatomy with exceptional tissue contrast. Includes ReadyBrain for single-click auto alignment, enabling patient planning through post processing.

    This extensive library of musculoskeletal imaging techniques enables you to image bone, joint and soft tissue with remarkable tissue contrast.

    OrthoWorks also includes 3D volumetric Cube with proton-density, combined with ASPIR, which enables improved fat suppression uniformity, which is routinely done as three separate 2D scans. With one 3D acquistion and multi planar reformats, Cubes may replace individual 2D scans.
  • PaedWorks

    Pediatric imaging requires exclusive and distinctive imaging techniques that provide ease of use for the user and clinical excellence for your smallest, most fragile patients.

    PaedWorks provides specialized protocols to simply address the needs of your smallest, most fragile patients. Techniques such as PB Navigators combined with PROPELLER MB are used with advanced techniques like diffusing imaging, allowing for patient-friendly, entirely free-breathing exams. Additionally, cardiac exams using single shot MDE provide faster, more reliable results.

    The four images demonstrate dynamic T1 imaging with PB Navigator, which enables the patient to breathe freely while capturing contrast in fast temporal phases. Whole spine evaluation can be obtained simply with routine T2 frFSE imaging.
