Typical 19F-MRS spectra from PFCE within an immunoisolation device (A) in vitro (SNR = 529; FWHM = 91 Hz) and (B) in vivo (SNR = 40.5; FWHM = 157.8 Hz). (C) The fitted inversion-recovery curve from the experiment that produced the in vivo spectrum (α = 0.861; β = 0.146; R1 = 0.985 s−1). FWHM, full width at half maximum; SNR, signal-to-noise ratio.
