目的:研究和分析多层螺旋CT在小肾癌诊断中的应用。方法:对我院46例经手术或病理确定为小肾癌患者的螺旋CT资料进行回顾性分析。结果:CT平扫中16例患者为等密度,28例患者为略低密度,2例患者为囊实性混杂密度。增强扫描中,皮质期36例患者强化程度不低于正常肾皮质,6例患者强化高于肾髓质而低于肾皮质,2例患者强化程度和肾髓质等同,2例患者囊实性病例囊壁明显强化。结论:多层螺旋CT多期增强扫描能够有效诊断小肾癌,具有重要作用。
Objective: To study and analyze the application of MSCT in the diagnosis of small renal cell carcinoma. Methods: The data of 46 cases of small renal cell carcinoma confirmed by surgery or pathology were analyzed retrospectively. Results: Sixteen patients underwent CT scan with equal density, 28 patients with slightly lower density, and 2 patients with cystic solid mixed density. In contrast enhancement, 36 patients with cortical phase had enhancement degree of no less than that of normal renal cortex, 6 patients were higher than that of renal medulla and lower than renal cortex, 2 patients had enhancement degree and renal medulla, 2 patients had cystic solidity Case wall was significantly enhanced. Conclusion: Multi-slice spiral CT multi-phase enhanced scan can effectively diagnose small renal cell carcinoma, which plays an important role.
