Kjersti Johnsrud

Kjersti Johnsrud is a Researcher at the Department of Radiology and Nuclear Medicine, University of Oslo, Faculty of Medicine. Her work primarily focuses on PET/CT imaging applications in oncology, cardiovascular disease, and neurological conditions.

• Current position: Postdoctoral Fellow
• Key affiliations: Oslo University Hospital (OUS) Rikshospitalet

Her research explores inflammation quantification in carotid artery plaques using 18F-FDG PET/CT, with significant contributions to understanding symptomatic vs. asymptomatic plaque inflammation. She has developed optimized respiratory-gated PET protocols for improved colorectal liver metastases assessment and lung cancer diagnostics.

Recent publications (2012-2022) demonstrate expertise in:

• Nuclear Medicine imaging techniques
• Radiology applications in disease diagnostics
• Inflammation biomarker validation
• Medical device innovation for surgery
• Neonatal hypoxia studies using dynamic PET

Key collaborators include Mona Elisabeth Rootwelt-Revheim, Therese Seierstad, and Arne Skretting in translational and clinical imaging research.
