目的探讨64排CT肾脏、肾上腺、肾动脉三合一扫描在继发性高血压病因筛查中的应用价值。方法利用飞利浦64排螺旋CT进行肾脏、肾上腺、肾动脉三合一扫描增强扫描,69例获得原始横断面图像后,采用容积再现(VR)、最大密度投影(MIP)、多平面重建(MPR)技术处理图像,29例行DSA检查或手术治疗。结果所有病例CT三合一扫描1次检查均获成功,显示肾上腺疾病25例,肾脏实质性病变9例,肾动脉狭窄35例。结论 64排CT一次检查可实现对肾脏、肾上腺、肾动脉的快速联合排查,是继发性高血压病因的有效筛查手段,具有重要临床应用价值。
Objective To investigate the value of three-in-one scanning of renal, adrenal and renal arteries in 64-slice CT in the screening of the etiology of secondary hypertension. Methods Three-in-one scans of renal, adrenal and renal arteries were performed with Philips 64-slice spiral CT. The original cross-sectional images of 69 patients were obtained. Volumetric reconstruction (VR), maximum density projection (MIP) Technical treatment of images, 29 cases of DSA examination or surgical treatment. Results All cases were successfully screened by CT triple scan, which showed 25 cases of adrenal diseases, 9 cases of renal parenchymal lesions and 35 cases of renal artery stenosis. Conclusion 64-slice CT can achieve a rapid examination of the kidney, adrenal and renal arteries simultaneously. It is an effective screening method for the etiology of secondary hypertension and has important clinical value.
