目的 分析CT对比增强倍增(CE-Boost)技术对肿瘤及其供血动脉显示的影响,探讨其在肾癌患者术前评估中的应用价值.资料与方法 回顾性分析2022年8月—2023年5月山东第一医科大学附属人民医院36例术后病理证实为肾透明细胞癌患者的CT影像资料.全部患者术前均行肾脏CT平扫及增强检查,采用CE-Boost技术将皮质期图像进行后处理,获得皮质期CE-Boost图像.将皮质期图像、皮质期CE-Boost图像分别设为A、B组.测量并记录两组图像中腹主动脉、肾动脉、肿瘤及其邻近肾皮质的CT值和图像噪声、脊柱两侧竖脊肌的噪声,分别计算肿瘤、腹主动脉和肾动脉的信号噪声比和对比度噪声比.由2名医师采用双盲法分别对肿瘤、肿瘤供血动脉及肾动脉的图像质量进行主观评分并进行比较.结果 B组中肿瘤、腹主动脉、右肾动脉及左肾动脉的CT值、信号噪声比和对比度噪声比均高于A组,差异均有统计学意义(t=-27.385～-5.267,P均=0.000).两组肿瘤、腹主动脉、右肾动脉及左肾动脉的噪声差异无统计学意义(t=-1.849～0.993,P均>0.05).两组肿瘤的主观评分均为好,差异无统计学意义(Z=-1.490,P=0.136),肿瘤供血动脉及肾动脉的评分B组高于A组,差异有统计学意义(Z=-3.512,P=0.000;Z=-2.127,P=0.033).结论 CT CE-Boost技术能提高肾脏增强CT的图像质量,对肿瘤供血动脉的显示更清楚.
Purpose To explore the application value of contrast enhancement boost(CE-Boost)technique in image quality of tumors and their feeding arteries in preoperative evaluation of renal cancer patients.Materials and Methods A total of 36 renal cancer patients in People's Hospital Affiliated to Shandong First Medical University from August 2022 to May 2023 with pathologically confirmed were retrospective collected.All patients underwent renal enhanced CT.The cortical phase images were post-processed using the CE-Boost technique to obtain CE-Boost images.The cortical phase images were set as group A and the CE-Boost images were set as group B.The CT value and image noise(SD)of abdominal aorta,renal artery,tumor and its adjacent renal cortex,and SD of the vertical spinal muscle on both sides of the spine of two groups were measured and recorded,and then the signal-to-noise ratio and contrast-to-noise ratio of tumor,abdominal aorta and renal artery were calculated.The image quality of the tumor,tumor feeding artery and renal artery was scored on 4 points by 2 doctors with double-blind method.Results The signal-to-noise ratio,contrast-to-noise ratio and CT value of group B were significantly higher than those of group A(t=-27.385--5.267,all P<0.05).The SD of tumor,abdominal aorta,right and left renal artery were not significantly different between group A and B(t=-1.849-0.993,all P>0.05).The subjective score of tumor in group A and B were no significant difference(Z=-1.490,P=0.136).However,the subjective score of tumor feeding arteries and renal arteries were significantly higher in group B than in group A(Z=-3.512,P=0.000;Z=-2.127,P=0.033).Conclusion The CT CE-Boost technique can improve the image quality of renal enhanced CT and provide visualization of tumor feeding arteries.
