CEST can selectively label the exchangeable hydrogen protons in free macromolecules.IVIM can evaluate true water molecule diffusion and microcirculation perfusion . Our research shows that CEST and IVIM have similar diagnostic performance in the differential diagnosis of NSCLC.
Figure.1 :A 62-year-old man with left Lung adenocarcinoma. A is T2w map,B is D pseudo colored map，C is f pseudo colored map, D is D* pseudo colored maps，E is Calculated B0 map,F is MTRasym(3.5ppm) pseudo colored maps.
Figure.2: The MTRasym (3.5ppm), D, D*, and f values of adenocarcinoma and squamous cell carcinoma groups. (A) MTRasym (3.5ppm) = (22.04±12.87)%, (8.25±6.77)% ; (B) D = (1.33±0.44) ×10−3 mm2/s , (0.89± 0.16)×10−3 mm2/s ; (C) D* = (67.34±68.22)×10−3 mm2/s , (25.66±24.43)×10−3 mm2/s; (D) f = (0.34±0.18), (0.26±0.09) .
