Redefine neurology CT
with NAEOTOM Alpha® Detect smaller structures with high precision


Reveal fine details in the brain

NAEOTOM Alpha with Quantum Technology® represents a quantum leap for high resolution CT imaging. Changing the dose vs. image-quality equation substantially, it offers a whole new level of detail while keeping dose to a minimum. Visualize small lesions and fine details – to aid clinical decisions in neurology.

Increased resolution, both in-plane and cross-plane, inherently available spectral imaging options, better image quality, and improved dose efficiency combine to enable a change at the front line of stroke and neurological care. Physicians can gain insight into details of the brain previously inaccessible or only accessible with greater effort. Say goodbye to compromising between resolution and dose, and provide more answers to more patients.


Redefining imaging at the front line of stroke care

At the Erasmus Medical Center in Rotterdam, the Netherlands, NAEOTOM Alpha with Quantum Technology has eclipsed conventional high-end CT scanners. Radiologist Anke van der Eerden, MD, talks about how Quantum HD ultra-thin slice thickness (up to just 0.2 mm) at standard dose has made all the difference and paved the way for photon-counting CT in clinical routine.

    Ultra-high resolution both in-plane and cross-plane

    Quantum HD images created by NAEOTOM Alpha offer optimized results without a dose increase. They make it possible to differentiate between white and grey matter with precision at low keV levels. Spectral imaging is inherently available without additional scans or effort. See for yourself.

    Ultra-high resolution in clinical routine

    NAEOTOM Alpha and its Quantum HD images come with a slice thickness of just 0.2 mm. The technology reduces radiation dose concerns about ultra-high resolution scanning and holds the potential to extend the utilization of ultra-high resolution imaging to a broader range of patients. Head scans are routinely prone to metal artifacts caused by dental implants, coils, flow diverters, and stents. Inherently available spectral information helps reduce these metal artifacts for neurovascular applications, which can add clarity to diagnostic assessments.

    Increased visibility of smaller vessels

    The unique Quantum Technology has the potential to reduce image noise and improve spatial and contrast resolution, pushing the boundaries for stroke pathways. This enables better visualization of small neurovascular structures and accurate characterization of vascular pathologies such as smaller vessel occlusions in ischemic stroke, aneurysm, arteriovenous malformations (AVMs), and stenoses.

    New diagnostic tools for treatment decisions

    Revealing fine details at a new level of resolution, Quantum Technology can contribute to diagnostic certainty. This applies especially in challenging scenarios, such as patients with cerebrospinal fluid (CSF) venous fistula, where the diagnosis changes patient’s well-being and quality of life.1

    With NAEOTOM Alpha, we can optimize the visibility of medium- and small-sized arteries in the brain.2

    The statements by Siemens Healthineers’ customers described herein are based on results that were achieved in the customers’ unique setting. Because there is no “typical” hospital and many variables exist (e.g., hospital size, samples mix, case mix, level of IT and/or automation adoption) there can be no guarantee that other customers will achieve the same results.
