Autoradiography results: a per cent binding in control lungs (n = 3), MCT lungs (n = 3) and SuHx lungs (n = 3) for [¹⁸F]EW-7197; b per cent binding in control lungs (n = 3), MCT lungs (n = 3) and SuHx lungs (n = 3) for [¹¹C]LR111; c Representative images of lung tissues for both tracers showing total binding (TB) and non-specific binding (NSB) in control lungs, MCT lungs and SuHx lungs. Error bars represent standard deviations. NSB images were obtained after blocking with SB431542. * represents a significant difference with SuHx lungs and MCT lungs (p < 0.05)
