Non‐invasive imaging of oxygen concentration in a complex in vitro biofilm infection model using 19F MRI: Persistence of an oxygen sink despite prolonged antibiotic therapy
Sign Up to like & getrecommendations! Published in 2019 at "Magnetic Resonance in Medicine"
DOI: 10.1002/mrm.27888
Abstract: Oxygen availability is a critical determinant of microbial biofilm activity and antibiotic susceptibility. However, measuring oxygen gradients in these systems remains difficult, with the standard microelectrode approach being both invasive and limited to single‐point measurement.… read more here.

DOI: 10.1002/mrm.27933
Abstract: To assess alveolar perfusion by applying dynamic susceptibility contrast MRI to 19F‐MRI of inhaled perfluoropropane (PFP). We hypothesized that passage of gadolinium‐based contrast agent (GBCA) through the pulmonary microvasculature would reduce magnetic susceptibility differences between… read more here.
