Renal and visceral artery images obtained concurrently with spiral CT and conventional arteriography were compared for 32 patients. Indications for imaging were occlusive disease (n = 12), aneurysmal disease (n = 9), and renal or visceral artery disease (n = 11). Conventional arteriography enabled visualization of 64 renal arteries and 15 accessory renal arteries. Lateral aortograms obtained in 15 patients enabled visualization of 14 superior mesenteric (SMA) and 14 celiac arteries. Spiral CT enabled visualization of 60 renal arteries, 12 accessory renal arteries, 27 SMAs, and 22 celiac arteries. Calcification or a disparity in timing of contrast material injection and scanning prevented visualization of the celiac artery in 10 patients and the SMA in four patients. With conventional arteriography as the standard for comparison, spiral CT had a sensitivity of 67% and a specificity of 95% for depiction of at least 75% stenosis in the main renal artery. By means of the Pearson correlation coefficient, significant correlation (p < 0.001) was confirmed between spiral CT and arteriography for evaluation of stenosis of the main renal artery, SMA, and celiac artery. This early experience suggests that spiral CT may be useful in evaluation of renal and visceral arteries and their relationship to aortic disease.
对32例患者同时采用螺旋CT和传统动脉造影获得的肾动脉和内脏动脉图像进行了比较。成像的适应证包括闭塞性疾病（n = 12）、动脉瘤性疾病（n = 9）以及肾动脉或内脏动脉疾病（n = 11）。传统动脉造影能够显示64条肾动脉和15条副肾动脉。15例患者的侧位主动脉造影能够显示14条肠系膜上动脉（SMA）和14条腹腔动脉。螺旋CT能够显示60条肾动脉、12条副肾动脉、27条SMA和22条腹腔动脉。钙化或造影剂注射与扫描时间的差异导致10例患者的腹腔动脉和4例患者的SMA无法显示。以传统动脉造影作为比较标准，螺旋CT对主肾动脉至少75%狭窄的显示敏感性为67%，特异性为95%。通过Pearson相关系数，证实螺旋CT与动脉造影在评估主肾动脉、SMA和腹腔动脉狭窄方面具有显著相关性（p < 0.001）。这一早期经验表明，螺旋CT可能有助于评估肾动脉和内脏动脉及其与主动脉疾病的关系。
