| 摘 要： | 目的:探讨64层CT灌注扫描技术在肾脏疾病诊断中的临床应用价值。方法:对40例符合入选标准的受检者行双肾灌注扫描,观察TDC形态,记录各组血流量(blood flow,BF)、血容量(blood volume,BV)、平均通过时间(mean transittime,MTT)、表面渗透性(permeability surface,PS)值,并进行统计学分析。结果:同一受检者两侧肾脏BF、BV和PS等参数差异无统计学意义(P>0.05)。肾脏肿瘤、肝硬化、高血压及正常组各组间BF、BV及PS差异均有统计学意义(P<0.05)。结论:CT灌注成像能从多方面对肾功能进行评价,具有良好的应用前景。 |

| Abstract: | Objective： To investigate the clinical application value of 64 slice spiral CT perfusion imaging in kidney diseases diagnosis. Methods： Totally 40 patients met the case criteria, 64-slice spiral CT was used for renal perfusion scan. To observe the sharp of TDC, to records and count BF,BV,MTT and PS of every group. Results： To she same client, the perfusion parameters, index of BF, BV and PS averages and standard deviations of both sides of the kidney had no significant difference （P〉0.05）. The BF, BV, MTT and PS among group of renal tumor, cirrhosis, hypertension and control had statistical differences （ P 〈0. 05）. Conclusion： CTPI technologies can evaluate renal function in many aspects, with a promising application prospect. |
