Abstract：Objective To sum up the MSCT (Multi-Slice CT) signs of gastric mucinous adenocarcinoma
in order to improve the accuracy of diagnosis. Methods The MSCT signs and clinical data of 101
clinically-and-pathologically-confirmed stomach cancers were retrospectively analyzed, including 26
cases of gastric mucinous adenocarcinoma and 75 cases of non-MUC (Non-Mucinous Adenocarcinoma).
The MSCT signs and clinical data of gastric mucinous adenocarcinoma were summarized and compared
with non-MUC. Results In the 26 gastric mucinous adenocarcinoma patients, 23 cases were male and
3 cases were female; the patients’ mean age was (65.1±3.4) years old; the predilection site was gastric
antrum. There was no statistically significant difference between the age, predilection site and sex ratio of
two groups (P<0.05). The gastric mucosa integrity rate was 92.3% (24/26); the layered enhancement rate
was 80.8% (21/26); the delayed reinforcement rate was 92.3% (24/26). There were significant differences
between the gastric mucosa integrity, the layered enhancement and delayed reinforcement of both groups
(P<0.05). Conclusion The gastric mucinous adenocarcinoma had certain imaging characteristics. When
the MSCT signs of gastric antrum were layered and delayed enhancement with the integrity of gastric
mucosa, it usually indicated gastric mucinous adenocarcinoma.
