Abstract 【Objective】To explore the diagnostic value of dynamic contrast-enhanced multi-slice spiral CT (MSCT) combined with three-dimensional imaging technology for gastric cancer. 【Methods】A total of 96 gastric cancer patients confirmed by gastroscopy pathology, including 80 cases of advanced gastric cancer and 16 cases of early gastric cancer.All patients underwent MSCT and three-dimensional imaging techniques. We compared the MSCT and three-dimensional imaging findings of patients with advanced and early gastric cancer with pathological diagnosis. 【Results】The MSCT scan results showed that 71 out of 80 patients with advanced gastric cancer had thickening of the gastric wall, abnormal enhancement of the lesion, narrowing of the gastric cavity, irregular depressions and circular protrusions visible on the surface of the lesion, and 9 cases had no obvious enhancement of the lesion. Among 16 early gastric cancer patients, 14 lesions were detected in the arterial phase, and 2 did not show enhancement. The scanning results of three-dimensional imaging technology showed that the lumen stenosis of 80 patients with advanced gastric cancer was more intuitive, and the lesions were moderately to significantly enhanced after enhancement; Among the 16 early gastric cancer patients, 10 lesions were detected in the arterial phase, showing uneven enhancement and a slow in slow out pattern, while 6 cases did not show significant enhancement. In MSCT diagnosis, the coincidence rate between advanced gastric cancer patients and pathological diagnosis was 71.25%(57/80), and the coincidence rate between early gastric cancer patients and pathological diagnosis was 50.00%(8/16), with a total coincidence rate of 67.71%(65/96). In the diagnosis of three-dimensional imaging technology, the coincidence rate between advanced gastric cancer patients and pathological diagnosis was 88.75%(71/80), early gastric cancer patients and pathological diagnosis was 56.25%(9/16), and the total coincidence rate is 83.33%(80/96). The diagnosis of MSCT combined with three-dimensional imaging technology was consistent with the pathological diagnosis results, with a combined diagnostic accuracy of 96.88%(93/96), which was higher than that of individual diagnosis (P<0.05). 【Conclusion】MSCT and 3D imaging techniques can be used for the differential diagnosis of advanced gastric cancer and early gastric cancer patients, and the combination of the two has a better diagnostic effect.
