Methods Radionuclide ambulatory renography and color Doppler renal hemodynamics were studied in 30 patients with esential hypertension and left ventricular hypertrophy and 21 healthy control group. The glomerular filtration rate,renal index and the distribution of intrarenal artery were investigated.The resistive index, the systolic peak velocity,andthe low diastolic flow velocity and acceleration time of theintrarenal arterial flow were measured. Results Compared with control group the density of intrarenal artery of patients with esential hypertension and left ventricular hypertrophy were significantly decreased.

对30例高血压伴左室肥厚病人及21例年龄相当的健康人对照组行核素动态肾功能检测及彩色多普勒超声肾血流动力学检查，测定肾小球滤过率和肾脏指数及肾内动脉分布，段动脉、叶间动脉的阻力指数，血流峰速加速时间，收缩期最大血流速度，舒张期末最低血流速度。

Methods The clinical data of 15 patients with cerebrospinal rhinorrhea, especially the results of radionudide dynamic eisternography were retrospectively analysed.

方法回顾性分析了15例脑脊鼻漏的临床资料，尤其是核素脑池动态扫描的结果。

Radionuclide dynamic cisternography plays an important role in assessing whether there is cerebrospinal rhinorrhea and determining the concrete situation of leakage.
