A comparative study of 32 patients with suspected deep venous thrombosis was carried out using blood-pool radionuclide scanning and conventional x-ray phlebography. Results of the two methods showed close agreement, the sensitivity (positive correlation) of the scan being 100% and its specificity 89%. We conclude that a patient's red cells labelled with 99mtechnetium (99mTc) provide an excellent medium for this type of scanning. The technique has particular advantages in visualising the whole venous system, giving a persisting image, and obviating the need to inject into a vein of the affected limb. In view of the inherent disadvantages of contrast phlebography, 99mTc-red-cell scanning is clearly an acceptable alternative.

对32例疑似深静脉血栓形成的患者进行了血池放射性核素扫描与传统X线静脉造影的对比研究。两种方法的结果显示出高度一致性，扫描的敏感性（正相关）为100%，特异性为89%。我们得出结论，用99m锝（99mTc）标记的患者红细胞为此类扫描提供了极佳的介质。该技术在显示整个静脉系统、提供持久图像以及无需向患侧肢体静脉注射方面具有特别的优势。鉴于静脉造影的固有缺点，99mTc红细胞扫描显然是一种可接受的替代方法。
