An abstract by researchers at Karolinska Institutet has received the Best Abstract Award at the Nature Conference "Redefining Healthcare in the Age of AI" in Paris. The work describes a framework called MEDLEY, which uses differences between AI models to make uncertainty in healthcare decisions more visible.

Karolinska Institutet, together with KTH, Stockholm University, and Region Stockholm, is undertaking a strategically important initiative in radiation therapy. Thanks to a donation of SEK 15 million from business leader Björn Savén, the establishment of a new center for medical radiation science is being strengthened. In addition, the donation will fund a project focused on precision radiation therapy.

Digital tomosynthesis (DTS) is an X-ray technique that provides sectional images with better lesion visibility than conventional chest radiology (CXR), while using for less radiation than CT. Masoud Jadidi will defend his thesis "Evaluation of image quality, radiation dose, and tumor size assessment in chest tomosynthesis" on August 21, 2026 where he evaluates digital thoracic tomosynthesis as a low-dose method in thoracic radiology.

The Docent Committee decided on June 9, 2026, to appoint Jeroen Goos as docent in radiology and medical imaging.

A new international study published in The Lancet Oncology shows that artificial intelligence (AI) can be more accurate than experienced radiologists in detecting pancreatic cancer on computed tomography (CT) scans. The study is a collaboration between Radboud University Medical Center in the Netherlands, Karolinska Institutet in Sweden, and the University of Bergen in Norway.

Can osteoporosis be detected in images taken for purposes other than fractures? According to radiologist Torkel Brismar, the answer is yes. He has explored this question in several studies.

Radiotherapy is a cornerstone of cancer care. However, in recent decades, Sweden has fallen behind in this area, both in terms of healthcare resources and research. Medicinsk Vetenskap has interviewed researchers who want to continue developing a bright idea.

Radiation oncologist Alexander Valdman conducts research at the Department of Oncology-Pathology at Karolinska Institutet. He works to ensure that patients with rectal cancer experience fewer side effects from their treatment.

Radiotherapy can cause long-term skin damage in cancer patients. New research shows that radiation creates a memory in skin cells that hinders healing, but also that antibodies can help restore the damage.

Neuroblastoma is a rare disease that affects children, often before the age of two. Some are born with the disease. Paediatric surgeon Jakob Stenman is investigating whether targeted radioactive drugs can slow down the disease in those with the most severe form.

Women who receive a false positive mammography result are more likely to develop breast cancer over the subsequent 20 years, report researchers from Karolinska Institutet in a study published in JAMA Oncology. The risk is highest for women aged between 60 and 75 and who have low breast density.

Aristeidis Grigoriadis, from the Gastroenterology and Rheumatology Unit at the Department of Medicine, Huddinge (MedH) will defend his thesis "Magnetic resonance imaging as a tool for diagnosis, evaluation and prognosis in patients with primary sclerosing cholangitis" on February 17, 2023. Main Supervisor is Annika Bergquist (MedH).

Susanne Fridsten at the research group Diagnostic Radiology, Department of Molecular Medicine and Surgery, will defend her thesis "Carcinoma of the uterine cervix: aspects on preoperative staging and assessment of treatment effect using magnetic resonance imaging" on April 21, 2022. Main Supervisor is Lennart Blomqvist.

Injuries in the nervous system of patients with severe COVID-19 are revealed by magnetic resonance imaging and computed tomography. In a study of 185 patients, researchers at KI and Karolinska University Hospital show an affection of microscopic blood vessels and inflammation in the brain, meninges and nerves. The results are published in Radiology.

João Ramos from the group Clinical Physiology at the Department of Molecular Medicine and Surgery will defend his thesis "Pulmonary hypertension and heart failure : physiological markers assessed by cardiovascular magnetic resonance" on May 8th, 2020. Main Supervisor is Martin Ugander.
