Neurology imaging with the NAEOTOM Alpha classDetect smaller structures with high precision


Reveal fine details in the brain

The NAEOTOM® Alpha class 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.

Seeing neurovascular microstructures with new clarity​

At Skåne University Hospital in Lund, Sweden, Johan Wasselius, MD, is using NAEOTOM Alpha to visualize even small cerebral vessels and aneurysms as well as neuro devices with remarkable precision – supporting fast, confident diagnoses.

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. Quantum Spectral Imaging is inherently available without additional scans or effort. See for yourself.

Ultra-high resolution in clinical routine

The NAEOTOM Alpha class and its Quantum HD images come with a slice thickness of just 0.2 mm as available with all NAEOTOM Alpha class systems. 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 Quantum Spectral Imaging 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 in the NAEOTOM Alpha class 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

Customer voices

Sharp insights during neuro imaging​

Marcel Dijkshoorn from Erasmus Medical Center in Rotterdam, the Netherlands, explains how NAEOTOM Alpha supports neuro imaging, particularly in follow‑up cases. The improved visualization of small structures helps clinicians evaluate complex conditions.

Redefining imaging at the front line of stroke care​

Anke van der Eerden, MD, Radiologist at Erasmus Medical Center in Rotterdam, the Netherlands, comments on the use of NAEOTOM Alpha with Quantum Technology in neuro imaging: “With NAEOTOM Alpha, we can reduce the slice thickness to just 0.2 mm at standard dose. This allows us to image small vessels in great detail.”
