- Abstract: Objective To explore the value of low-dose multi-slice spiral computed tomography (MSCT) multi-stage scan and three-dimensional reconstruction in diagnosis of patients with gastric carcinoma.Methods A total of 40 patients with gastric carcinoma were selected.All the patients were conducted with low-dose MSCT scan,dynamic contrast scanning and three-dimensional reconstruction scan,and then were processed by multi-planar reconstruction,volume reconstruction and CT virtual endoscopy.Primary lesions in gastric cancer,peripheral infiltration and distant metastasis were observed.Results All the patients were satisfied with the low dose MSCT images,and all of them found primary gastric lesions and had satisfactory diagnosis rates of gastric peripheral infiltration,lymph node metastasis and distant metastasis.Conclusion Low-dose MSCT multi-stage scan and three-dimensional reconstruction can reduce the radiation dose and reveal the primary gastric lesions,gastric peripheral infiltration and distant metastasis.
