容易和肾结石混淆的超声征象

Bright Reflectors Within the Kidney
? Figure 1. Renal arterial system. Note the proximity of the segmental artery divisions and the relationship of the arcuate arteries to the bases of the renal pyramids.
?
肾脏动脉系统。肾段动脉与锥体基底部的弓状动脉的关系。
Vascular Reflectors segmental artery
? Figure 2. A and B, Coronal sections of the kidney. Arrows mark a segmental artery. C, Renal Doppler image showing the profuse vascular nature of the kidney. 箭头显示肾段动脉。
?
Vascular Reflectors Arcuate Arteries
? Figure 3. Arcuate artery (arrow). Note its orthogonal relationship to the ultrasound beam and its double-channel appearance. 弓状动脉。与超声束垂直，呈双管状。光斑位于锥体的基底部，这个地方正好是弓状动脉。
Nonvascular Reflectors: Prominent Papillae 肾乳头
? Figure 4. Renal pyramids肾脏锥体. Echogenic tips of the renal pyramids肾锥体顶端乳头处回声增强 as seen in mild hydronephrosis也可看到轻度的肾盂积水 are shown.
? These structures can also appear echogenic in conditions such as 很多疾病可以导致这种表现early medullary nephrocalcinosis早期的 肾髓质钙质沉着 (Anderson-Carr progression),2 papillary necrosis乳头坏死, medullary sponge kidneys髓质海绵肾, infection病毒感染 with Cytomegalovirus or Candida albicans, and medullary fibrosis 髓质的纤维变性.
Nonvascular Reflectors: Prominent Papillae
? Figure 5. Transient pyramidal echogenicity暂时性锥体回声增强. These images of an 8-day-old neonate show the characteristic appearance of transient pyramidal echogenicity due to the precipitation of Tamm-Horsefall proteins. These findings disappeared by 6 weeks of age. 一8天大新生儿出现这种表现 ......
