摘要
目的探讨三维血管能量显像在移植肾急性排异血流显像中的临床价值。方法应用三维血管能量显像技术对88例患者的同种异体移植肾进行了血流分级与观察。结果88例移植肾重建图像满意率为95．5％。正常移植肾30例，三维血管能量显像血流分级在4～5级；急性排异58例，血流分级在0～4级。血流分级与移植肾急性排异治疗后的肾血流开始改善时间及肾功能开始恢复时间密切相关，r值分别为-0．9224、-0.9223，P〈0．01。结论三维血管能量血流分级从形态学上直观地反映了肾内血流灌注状况，为评价移植肾的血流动力学提供了一项新的半定量指标。
Objective To study the clinical value of three-dimensional vascular reconstruction of power Doppler imaging in monitering acute rejection of renal transplant. Methods Eighty-eight renal allograft patients were studied by three-dimensional vascular reconstruction and graded the vascular flow. Results The ratio of successful renal transplant three-dimensional vascular reconstruction reached 95.5% in 88 cases. Blood flow gradation was 4-5 levels in 30 controls and 0-4 levels in 58 patients with acute renal transplant rejection. Blood flow gradation was closely relevant to the time when the blood flow began to improve and the renal function began to restore after treatment, value of r being - 0. 9224 and - 0. 9223 respectively （ P 〈0. 01）, Conclusions Threedimensional vascular power Doppler gradation could directly reflect the perfusion of renal transplant in morphology and provide a new semi-quantitative parameter as well as scientific basis for early diagnosis, early treatment and prognosis judgment of acute renal transplant rejection.
