PET-MR is a new multi-modal imaging system that
combines PET and MRI. SUVmax is an indicator to measure the uptake of 18F-FDG
in the lesion. IVIM includes D, D*, and f values. The results show that SUVmax and IVIM have
similar diagnostic performance in lung squamous and adenocarcinoma.
Figure.1: a-d）A 35-year-old male with adenocarcinoma of the
upper left lobe. In these images, a is PET image，b is D pseudo colored map，c is f pseudo colored map, d is D* pseudo colored map.
Figure.2: The SUVmax, D, D*, and f values of the squamous
carcinoma and adenocarcinoma group. (a) D = (1.29±0.38)×10-3 mm2/s, (0.95±0.20)×10-3 mm2/s
; (b) f =
(29.91±16.64)%, (18.67±12.15)% ; (c) D* = (64.12±67.91)×10-3 mm2/s, (21.28±22.19)×10-3 mm2/s
; (d) SUVmax = (6.55±4.26), (12.56±5.85).
