OBJECTIVE
to report and discuss preliminary results obtained in varicose limbs by means of a volume rendering (VR)-computed tomography (CT) technique without contrast medium injection.
MATERIALS AND METHODS
VR-CT and duplex sonography (US) were performed to visualise the superficial veins of the lower extremity in eight healthy and 12 varicose limbs.
RESULTS
VR-CT clearly demonstrated the 3D arrangement of the superficial veins and visualised small sized veins which were not visible at US examination.
CONCLUSIONS
VR-CT is not suitable for routine evaluation of varicose limbs. VR-CT 3D reconstructions may be useful in the evaluation of atypical varicosis. Further studies are needed to define the role of VR-CT in deep venous disease.
目的
报告并讨论通过容积再现（VR）-计算机断层扫描（CT）技术在不注射造影剂的情况下对静脉曲张肢体获得的初步结果。
材料与方法
对8例健康肢体和12例静脉曲张肢体进行VR-CT和双功超声检查（US）以观察下肢浅静脉。
结果
VR-CT清晰显示了浅静脉的三维排列，并显示出在超声检查中不可见的小静脉。
结论
VR-CT不适用于静脉曲张肢体的常规评估。VR-CT三维重建在非典型静脉曲张的评估中可能有用。需要进一步研究以确定VR-CT在深静脉疾病中的作用。
