[Abstract] Objective: To analyze introvoxel incoherent motion (IVIM) MR sequence features and the difference between carcinoma of gastric cardia and normal cardia.Materials and Methods: MR imaging data of 20 patients with gastric cardia carcinoma and 20 patients of normal cardia were analyzed retrospectively. All patients underwent routine MR scan and biexponential model IVIM sequence. The IVIM parameters (Standard ADC, D, D* and f) of gastric cardia carcinoma and normal cardia were measured and analyzed by using t test.Results: The Standard ADC, D, D* and f of gastric cardia carcinoma group were (1.18±0.35)×10-3 mm2/s, (0.63±0.67)×10-3 mm2/s, (21.29±18.83)×10-3 mm2/s, 0.37±0.37, and those of normal cardia group were (1.56±0.38)×10-3 mm2/s, (1.32±1.06)×10-3 mm2/s, (8.59±3.98)×10-3 mm2/s, 0.70±0.22. The differences of these parameters between two groups were statistically significant (t=2.920, 2.473, 2.325, 2.923, P=0.006, 0.027, 0.019, 0.006). No differences showed between standard ADC and D in both gastric cardia and normal groups (t=3.073, 0.868, P=0.543, 0.326).Conclusions: The Standard ADC and D of gastric cardia carcinoma group showed lower than normal cardia group, the D* appeared higher than normal group, which may play a complementary role in the diagnosis of gastric cardia carcinoma.
