7T 19F/1H MRI with perfluorocarbon‐labeled immune cells in pigs: Pilot results with a dedicated twin‐array system with pTX support

Magnetic Resonance in Medicine, Volume 95, Issue 1, Page 51-61, January 2026.
Abstract Purpose Cardiac inflammation plays a key role in many diseases. However, its underlying mechanisms and progression remain poorly understood. Using an ultra‐high field (UHF) may increase the sensitivity of MRI of inflammatory processes with 19F‐labeled immune cells.
