We present the utility of a under-sampled single-shot turbo spin-echo (TSE) sequence for high resolution T₂ mapping and imaging of the lungs using hyperpolarized carbon-13 agents. We then demonstrate the possibility of using this sequence selectivity excite different carbon-13 species via a minimum-phase frequency-selective excitation pulse.
