【摘要】：目的探讨能谱CT在卵巢良恶性肿瘤诊断中的价值。方法回顾性分析行盆腔能谱CT增强扫描且经手术病理确诊患者58例,按照病理结果分为良性组(n=30)和恶性组(n=28),测量两组动脉期和静脉期碘含量、水含量、40~140 ke V单能量下(间隔10 ke V)平均CT值、40~100 ke V间能谱曲线斜率及能谱曲线形态。对比分析病理及影像结果。结果两组病变在动脉期和静脉期随着单能量增大能谱曲线形态呈弧形下降型,能量越低CT值差异越大;动脉期单能量40~100 ke V间良性组CT值、能谱曲线斜率均小于恶性组,差异有统计学意义(P0.05);静脉期60~140 ke V间良性组CT值均大于恶性组,差异有统计学意义(P0.05);动脉期良性组碘含量小于恶性组,差异有统计学意义(P0.05);能谱CT对良性和恶性肿瘤的检出率分别为86.67%和85.71%,灵敏度分别为86.67%和80.00%,特异度分别为80.00%和86.67%,能谱CT与病理结果差异无统计学意义(Kappa值为0.72),一致性较高。结论能谱CT多参数分析对卵巢原发良恶性肿瘤的诊断具有一定参考价值。
[Abstract]:Objective to evaluate the value of energy dispersive CT in the diagnosis of ovarian benign and malignant tumors. Methods 58 patients with pelvic energy dispersive CT enhanced scanning and confirmed by operation and pathology were retrospectively analyzed. According to the pathological results, 58 patients were divided into benign group (NN30) and malignant group (NC28). The iodine content and water content in arterial and venous phases were measured in both groups. At the single energy level of 40 ~ 140 ke V, the mean CT value of 10 ke V) interval, the slope of the energy spectrum curve between 40 ~ 100 ke V and the shape of the energy spectrum curve line are obtained. The pathological and imaging results were compared and analyzed. Results in the arterial phase and the venous phase, the energy spectrum curve of the two groups decreased with the increase of single energy. The lower the energy, the greater the difference of CT value between the two groups. The slope of the energy spectrum curve in the benign group was significantly lower than that in the malignant group (P0.05), and the CT value in the benign group was higher than that in the malignant group (P0.05), and the CT value in the benign group was higher than that in the malignant group (P0.05). The iodine content in benign group was significantly lower than that in malignant group (P0.05). The detection rate of EDS CT for benign and malignant tumors was 86.67% and 85.71%, the sensitivity was 86.67% and 80.005%, the specificity was 80.00% and 86.67%, respectively. There was no significant difference between CT and pathological results (Kappa = 0. 72). Conclusion the multiparameter analysis of energy spectrum CT has certain reference value for the diagnosis of ovarian primary benign and malignant tumor.
