Stakeholders' perspective on sustainable cement made with naturally occurring radioactive by-products: A cross-country comparison.

The use of industrial by-products as substitutes for raw materials in cement production not only reduces raw material use, thereby contributing to the circular economy, but also offers an avenue for reducing greenhouse gas emissions. This study investigates the perceptions of industry representatives and end-users across Belgium, Czechia and Slovenia regarding alternative cement made with industrial by-products categorised as naturally occurring radioactive materials. Based on 66 interviews, three main concerns were discerned: health, performance, and economic.

The perspectives of neurologists on positron emission tomography utility in multiple sclerosis: A qualitative study.

Background: Magnetic resonance imaging (MRI) is the gold standard for imaging disease activity in multiple sclerosis (MS) patients. However, recent studies indicate that positron emission tomography (PET) may provide added value in visualizing MS disease in the future.

Objective: This study aims to investigate the barriers to implementing PET for MS patients and its potential added value in the context of MS.
