Improved lower extremity venography has been achieved by a distally directed superficial foot venipuncture. Supine position and short procedure time afford excellent patient acceptance. Dilute contrast is believed responsible for eliminating venospasm and postvenography phlebitis; the low sodium concentration permits safe evaluation of cardiac patients. Sequential imaging (and the use of anteroposterior and lateral projections) eliminates false positive and negative interpretations. Skip areas are avoided by the use of 90-cm (36-inch) cassettes.
通过向足部远端进行浅表静脉穿刺，下肢静脉造影得到了改进。仰卧位和较短的操作时间使患者的接受度很高。稀释造影剂被认为可消除静脉痉挛和造影后静脉炎；低钠浓度允许对心脏病患者进行安全评估。连续成像（以及使用前后位和侧位投影）可消除假阳性和假阴性的解读。使用90厘米（36英寸）的暗盒可避免出现遗漏区域。
