Changes in X-ray attenuation of rabbit V2 carcinoma, as determined by computed tomography (CT) scanning, were assessed following the intraarterial and intravenous administration of a water soluble contrast agent. After intraarterial contrast medium administration, a significant increase in CT attenuation values occurred in both blood and V2 carcinoma, and the attenuation values remained above control values for at least 120 min. A similar, although less pronounced, increase in VA attenuation values occurred following intravenous contrast medium administration. Comparison of V2 CT enhancement values after intraarterial and intravenous administration suggested that tumor enhancement was greater after intraarterial administration.
通过计算机断层扫描（CT）扫描测定兔V2癌X线衰减的变化，在动脉内和静脉内给予水溶性造影剂后进行评估。动脉内给予造影剂后，血液和V2癌的CT衰减值均显著增加，且衰减值至少在120分钟内保持高于对照值。静脉内给予造影剂后，VA衰减值也出现了类似但不太明显的增加。动脉内和静脉内给药后V2 CT增强值的比较表明，动脉内给药后肿瘤增强更大。
