摘要
目的:探讨能谱CT优化胃肿瘤扫描辐射剂量对肾上腺嗜铬细胞瘤的诊断价值。方法:采用回顾性、抽样、随机研究方法选择2012年9月到2017年2月在我院诊治的肾上腺嗜铬细胞瘤患者59例作为研究对象,所有患者都给予常规CT扫描与能谱CT优化胃肿瘤扫描,记录和比较辐射剂量与图像质量。结果:所有病例包膜均完整,边缘清楚,肿瘤内见单发或多发低密度区,肿瘤实质区呈不均匀显著强化。常规CT与能谱CT的图像质量主观评分分别为3.89±0.45分和4.54±0.34分;常规CT与能谱CT图像的胃肿瘤CT值分别为31.94±6.39HU和35.29±5.19HU,对比都有显著差异(P<0.05)。能谱CT图像的膀胱和皮下脂肪图像噪声值都显著低于常规CT图像,对比差异都有统计学意义(P<0.05);能谱CT扫描的CTDIvol和DLP分别为12.39±3.48mGy和624.10±39.19mGy.cm,都显著低于常规CT扫描的14.09±4.13mGy和653.92±56.29mGy.cm(P<0.05)。结论:能谱CT优化胃肿瘤扫描在肾上腺嗜铬细胞瘤诊断中的应用能有效减少辐射剂量与图像噪声,提高图像CT值与主观质量,临床应用价值更高。
Objective: To explore the diagnostic values of spectrum CT optimized gastric tumor scanning radiation dose for adrenal pheochromocytoma. Methods: A retrospective, randomized study was performed from September 2012 to February 2017, 59 patients of adrenal pheochromocytoma in our hospital were selected as the research object, all patients were given spectrum CT optimized gastric tumor scanning and conventional CT scanning, the radiation dose and image quality were recorded and compared.Results: All patients were showed intact, the edges were clear, single or multiple low density areas were found in the tumor, and the tumor parenchyma were inhomogeneous and significantly enhanced. The subjective scores of image quality of conventional CT and spectrum CT were 3.89±0.45 points and 4.54±0.34 points, respectively. The CT values of gastric tumors in routine CT and spectrum CT images were 31.94± 6.39 HU and 35.29±5.19 HU, respectively, with compared were significantly difference(P<0.05). The bladder and subcutaneous fat image noise values in the spectrum image CT were significantly lower than that of the conventional CT image, the difference were statistically significant(P<0.05); The CTDIvol and DLP in the spectrum image CT were 12.39±3.48 mGy and 624.10±9.19 m Gy.cm were significantly lower than that of the conventional image CT of 14.09±4.13 mGy and 653.92mGy±56.29 mGy.cm(P<0.05). Conclusions: Spectrum CT optimized gastric tumor scanning radiation dose can effectively radiate dose and image noise, improve image CT and subjective quality for adrenal pheochromocytoma, and it has a good application value.
