18F-fluorodeoxyglucose positron emission tomography/computed tomography comparison of gastric lymphoma and gastric carcinoma

Table 2 Incidence, pattern and intensity of gastric ¹⁸F-FDG uptake in patients with gastric lymphomas and gastric carcinomas n (%)

	Gastric lymphoma	Gastric carcinoma	P value
Presence of gastric FDG uptake	52 (100)	72 (98.63)	0.9571
Gastric FDG uptake > liver	49 (94.23)	65 (89.04)	0.8291
PET/CT pattern
Type I	23 (44.23)	9 (12.33)	0.0021
Type II	22 (42.31)	14 (19.18)	0.0381
Type III	7 (13.46)	50 (68.49)	< 0.0011
SUVmax (mean ± SD)	13.39 ± 9.24	8.35 ± 5.80	< 0.0012
SUVmax/THKmax (mean ± SD)	7.96 ± 4.02	4.88 ± 3.32	< 0.0012

¹The value was compared by Pearson χ² test;

²The value was compared by Student's t test. FDG: Fluorodeoxyglucose; PET/CT: Positron emission tomography/computed tomography; SUVmax: Maximal standard uptake value; THKmax: The maximal thickness.
