摘　　要：目的:探讨与分析256层螺旋CT增强三维重建对结直肠癌远处转移的诊断价值。方法:回顾性收集2020年6月至2024年1月,本院诊治的89例结直肠癌患者临床资料,根据远处转移情况分为远处转移组29例和非转移组60例。所有患者均行256层螺旋CT增强三维重建检查,记录成像质量与CT相关参数,以手术结果为金标准,判断CT增强三维重建诊断的价值。结果:89例患者中,手术发现远处转移者29例,其中肝脏转移18例,肺转移7例,盆腔转移4例。2组在三维重建图像评分、客观噪声和信噪比方面比较,差异无统计学意义(P>0.05)。远处转移组毛刺征、环状晕征、肠腔狭窄、肠壁僵硬和肠壁环形增厚的占比分别为86.21%、93.10%、86.21%、86.21%和93.10%,显著高于非转移组35.00%、36.67%、50.00%、43.33%和50.00%,差异有统计学意义(P<0.05)。远处转移组CT轻度强化3例,中度强化4例,重度强化22例;非转移组分别为39例、11例和10例,差异有统计学意义(P<0.05)。256层螺旋CT增强三维重建判断远处转移者28例,诊断的敏感性、特异性和准确性分别为96.55%、100.00%和98.88%。结论:结直肠癌远处转移比较常见,以肝转移为主,远处转移患者多表现为毛刺征、肠腔狭窄、肠壁僵硬、肠壁环形增厚及环状晕征等CT征象,伴随有CT强化程度增高,256层螺旋CT增强三维重建对结直肠癌远处转移具有很高的诊断价值。Objective To explore and analyze the diagnostic value of enhanced scanning and three-dimensional reconstruction with 256-slice spiral CT in distant metastasis of colorectal cancer. Methods The clinical data of 89 patients with colorectal cancer diagnosed and treated in our hospital from June 2020 to January 2024 were retrospectively collected.According to the situation of distant metastasis, they were divided into the distant metastasis group with 29 cases and the non-metastasis group with 60 cases.All patients underwent enhanced scanning and three-dimensional reconstruction with 256-slice spiral CT.The imaging quality and CT-related parameters were recorded. Taking the surgical results as the gold standard, the diagnostic value of enhanced scanning and three-dimensional reconstruction with CT was determined. Results Among the 89 patients, 29 cases of distant metastasis were found during the operation, including 18 cases of liver metastasis, 7 cases of lung metastasis, and 4 cases of pelvic metastasis. There were no significant differences in the three-dimensional reconstruction image score, objective noise, and signal-to-noise ratio between the two groups(P>0.05).The proportions of spicule sign, circular halo sign, intestinal stenosis, intestinal wall stiffness, and annular thickening of the intestinal wall in the distant metastasis group were 86.21%, 93.10%, 86.21%,86.21%,and 93.10%,respectively, which were significantly higher than those in the non-metastasis group(35.00%,36.67%,50.00%,43.33%,and 50.00%), and the differences were statistically significant(P<0.05).In the distant metastasis group, there were 3 cases of mild CT enhancement, 4 cases of moderate CT enhancement, and 22 cases of severe CT enhancement.In the non-metastasis group, there were 39 cases of mild CT enhancement, 11 cases of moderate CT enhancement, and 10 cases of severe CT enhancement, respectively, and the difference was statistically significant(P<0.05).The enhanced scanning and three-dimensional reconstruction with 256-slice spiral CT d
