Three-dimensional volume-rendered computed tomographic (CT) angiography represents an increasingly important clinical tool that, in many institutions, is replacing conventional angiography in the depiction of normal vascular anatomy and the diagnosis of vascular disorders. Evaluation of conditions affecting the renal vasculature constitutes a major focus of volume-rendered CT angiography, which has documented utility for demonstrating both arterial and venous disease. Arterial disorders include renal artery stenosis, renal artery aneurysms, and dissection. Venous disorders include splenorenal shunts, thrombosis, and intravascular tumor extension. In addition, volume-rendered CT angiography accurately displays the normal and variant renal vascular anatomy, which is crucial to detect before surgery, especially partial nephrectomy and laparoscopic nephrectomy. CT angiography is also useful in the evaluation of the renal vasculature following renal transplantation. Familiarity with proper CT protocols and data acquisition techniques are crucial for accurate diagnosis.
三维容积再现计算机断层扫描（CT）血管造影术是一种日益重要的临床工具，在许多机构中，它正在取代传统血管造影术来描绘正常血管解剖结构和诊断血管疾病。对影响肾血管系统疾病的评估是容积再现CT血管造影术的一个主要重点，它已被证明在显示动脉和静脉疾病方面都很有用。动脉疾病包括肾动脉狭窄、肾动脉瘤和夹层。静脉疾病包括脾肾分流、血栓形成和血管内肿瘤扩展。此外，容积再现CT血管造影术能准确显示正常和变异的肾血管解剖结构，这在手术前检测至关重要，尤其是部分肾切除术和腹腔镜肾切除术。CT血管造影术在肾移植后肾血管系统的评估中也很有用。熟悉适当的CT方案和数据采集技术对于准确诊断至关重要。
