Intraindividual Comparison of Half-Dose Gadopiclenol and Standard-Dose Gadobenate Dimeglumine for Contrast-Enhanced Abdominal MRI.
Journal Article J Magn Reson Imaging · January 20, 2026 BACKGROUND: Gadopiclenol is a high-relaxivity contrast agent enabling dose reduction while maintaining image quality. However, comparison with conventional agents remains limited in body MRI. PURPOSE: To intra-individually compare half-dose gadopiclenol an ...

Journal Article Eur Radiol · November 2025 OBJECTIVES: The efficacy of focal therapy (FT) has improved with the use of multiparametric MRI (mpMRI) for lesion identification, though standardized mpMRI reporting post-FT is lacking. The Prostate Imaging after Focal Ablation (PI-FAB) scoring system was ... Full text Link to item CiteRecent Grants
