A technique for radiographic delineation of the microvasculature of the canine kidney is described. The renal vasculature was perfused (at a physiologic pressure) with a finely divided barium sulfate. Microangiograms of sagittal renal slices were produced, using a special radiography machine that allows low kilovolt peak, low milliamperage, and exposure times up to 5 minutes. A special high resolution film (800 lines/mm) was used. With this technique, it was possible to delineate interlobar, arcuate, and interlobular arteries, afferent arterioles, glomerular capillaries, and peritubular vessels. The kidney slices prepared for microangiography were undamaged and available for histochemical processing. Thus, the microvascularity was correlated with the histologic appearance of the renal tissues.
本文描述了一种用于X线描绘犬肾微血管系统的技术。通过（在生理压力下）用细分的硫酸钡灌注肾血管系统。使用一台允许低千伏峰值、低毫安以及曝光时间长达5分钟的特殊射线照相机器，制作肾矢状切片的微血管造影照片。使用了一种特殊的高分辨率胶片（800线/毫米）。通过这种技术，可以描绘叶间动脉、弓状动脉和小叶间动脉、入球小动脉、肾小球毛细血管和肾小管周围血管。为微血管造影准备的肾切片未受损，可用于组织化学处理。因此，微血管系统与肾组织的组织学外观相关联。
