A scientific breakthrough with immediate clinical impact: Ultra-high-resolution PET imaging supports early detection, clinical decision-making, and neuroscience research

ROTTERDAM, Netherlands, June 12, 2026 /PRNewswire/ -- UZ Leuven and KU Leuven from Leuven, Belgium have introduced the NeuroEXPLORER PET into clinical practice, one of the world's most advanced ultra-high resolution PET scanners delivered by United Imaging Healthcare. The system has been operational for six months and has already supported imaging in over 400 patients. It marks a transformative milestone in molecular brain and head & neck imaging, enabling visualization of structures and circuits in patients at near-millimetre resolution that were previously inaccessible in living patients.

Early Detection and Precision Diagnosis

Working with the NeuroEXPLORER PET enables researchers and clinicians to identify disease processes at the very earliest stages of disease, particularly in neurodegenerative diseases such as Alzheimer's, Parkinson's and ALS. By detecting the effects of key chemical signals associated with these diseases, the system enables earlier and more precise diagnosis, as well as the detection of very small abnormalities, including brain tumours. According to Koen Van Laere, Professor of Nuclear Medicine and Principal Investigator: "This technology fundamentally changes how we can investigate the origins and diagnoses of neurological and psychiatric diseases, as well as vascular diseases and head- and neck disorders such as tumours. It allows us to measure disease processes in very small structures with unprecedented precision."

Clinical and research applications

The scanner contributes to both fundamental and prospective clinical research programs, including:

• Neurodegeneration (Alzheimer's disease, Parkinson's disease, Amyotrophic lateral sclerosis (ALS))
• Drug-resistant epilepsy in adults and children
• Deep brain stimulation planning in Parkinson, OCD and epilepsy
• Brain vessel inflammation and carotid artery plaque imaging to assess stroke risk
• Accurate detection and staging of brain, head & neck tumours, pituitary and parathyroid adenoma

The system enables very precise localisation and quantification of key biological processes in the brain, including synaptic density, tau and amyloid accumulation, dopaminergic and noradrenergic systems in small brain stem nuclei, microglial activation in neuroinflammation, and metabolic brain connectivity. Comparative studies with standard-of-care imaging already indicate improved individual treatment decisions.

Advancing neurosurgical precision

For neurosurgical procedures such as the treatment of small pituitary tumours and deep brain stimulation, precise targeting is critical. Thomas Decramer, neurosurgeon at UZ Leuven, said: "Ultra-high resolution imaging improves our ability to define optimal resection of microtumours in the pituitary that overproduce certain hormones, and also improves the placement of electrodes for neurostimulation. This has direct implications for successful surgical outcomes and for rendering patients disease free in cases of pituitary tumours." The combination of very high sensitivity and ultra-high spatial resolution supports applications ranging from neurodegenerative diseases and epilepsy to vascular disorders and neuroinflammation, expanding opportunities for both clinical investigation and patient care.

Expanding opportunities for research and collaboration

Mathieu Vandenbulcke, Chair of the Leuven Brain Institute, said: "The NeuroEXPLORER strengthens Leuven's international position in brain research and precision medicine. It creates a unique platform for global scientific collaboration."



Over the next five years, the scanner will support more than thirty large-scale research programs across neurodegeneration, psychiatry, epilepsy, neuromodulation, inflammation and oncology. Among them are studies investigating brain stem nuclei affected in the earliest stages of Alzheimer's disease, with the aim of improving understanding of disease progression and supporting more personalised treatment approaches.

Wenige Stunden vor dem offiziellen Start der Fußball-Weltmeisterschaft 2026 geraten die Vereinigten Staaten als Gastgeberland wegen ihrer Migrations- und Einreisepolitik unter wachsenden internationalen Druck. Der UN-Hochkommissar für Menschenrechte, Volker Türk, rief Washington dazu auf, die Umsetzung seiner migrationspolitischen Vorgaben „in der Tiefe“ zu überprüfen. Anlass sind eine Reihe von Zwischenfällen rund um die Anreise von Spielern und Delegationen, die die Debatte über die Vereinbarkeit der US-Praxis mit internationalen Menschenrechtsstandards neu entfacht haben.

Besonders kritisiert werden administrative Hürden und Pannen bei der Einreise, von denen laut Türk auch offizielle Delegationen betroffen waren. In diesem Zusammenhang werden unter anderem Probleme beim Zugang zu Visa und Kontrollen bei der Ankunft genannt; ein Fokus liegt auf den Schwierigkeiten, mit denen Vertreter des Iran konfrontiert gewesen sein sollen. Für den Menschenrechtschef der Vereinten Nationen steht dabei weniger die grundsätzliche Souveränität der USA in Migrationsfragen im Zentrum, als vielmehr die Art und Weise, wie diese Politik angewendet wird und welche Folgen sie für die „Menschenrechte und die menschliche Würde“ hat.

Türk appellierte in einer Pressekonferenz in Genf an die US-Regierung, gerade mit Blick auf die Weltmeisterschaft die bestehenden Verfahren zu überdenken. Die aktuell vorherrschenden Politiken müssten so angepasst werden, dass sie den Anforderungen eines globalen Sportereignisses besser gerecht werden, sagte er sinngemäß. Die Erwartung der UN-Seite: Ein Regime, das einerseits die Sicherheitsinteressen des Gastgeberlandes wahrt, andererseits aber die Bewegungsfreiheit von Spielern, Funktionären und Fans nicht unnötig einschränkt oder zu demütigenden Situationen führt.

Der Weltverband FIFA versucht derweil, Distanz zur Auseinandersetzung zu halten und verweist auf die Zuständigkeit des Gastgeberstaates. Man greife nicht in Einwanderungsverfahren oder Visa-Entscheidungen des Austragungslandes ein, betont die Organisation. Dennoch wächst die Sorge, dass ungeklärte Fragen im Grenz- und Visaregime weitere Reibungsverluste produzieren und damit den Ablauf des Turniers stören könnten. Sollten die kritisierten Punkte nicht rasch adressiert werden, drohen die organisatorischen Probleme, die Erzählung der WM schon vor dem ersten Anpfiff zu überlagern.
