摘　　要：目的:探究能谱CT对直肠癌淋巴结转移测定的价值。方法:选取包头医学院第二附属医院行腹腔镜下直肠癌根治术的50例患者,共纳入225枚淋巴结,其中转移性淋巴结51枚,非转移性淋巴结174枚。对比分析转移性淋巴结与非转移性淋巴结的长径、短径、长短径之比,同时对各淋巴结的能谱参数进行对比分析。结果:转移性淋巴结组与非转移性淋巴结组的长径、长短径之比具有统计学意义(P Objective: To explore the value of spectral CT in the determination of lymph node metastasis in rectal cancer. Methods: A total of 225 lymph nodes were included in 50 patients who underwent laparoscopic radical rectal cancer resection in the Second Affiliated Hospital of Baotou Medical College, including 51 metastatic lymph nodes and 174 non-metastatic lymph nodes. The ratios of long diameter, short diameter and long short diameter of metastatic lymph nodes and non-metastatic lymph nodes were compared and analyzed, and the energy spectrum parameters of each lymph node were compared and analyzed. Results: The ratio of length to diameter between metastatic lymph node group and non-metastatic lymph node group was statistically significant (P < 0.05). In arteriovenous phase, IC, NIC and substance were statistically significant compared with Water-Iodine, Iodine-Fe, Fe-Iodine, Iodine-Cu, Cu-Iodine and Blood-Iodine (P < 0.05). Conclusion: Spectral CT has a high differential value in determining whether lymph nodes metastasize in rectal cancer.
