Contact thermography, a non-invasive inexpensive method of investigation for the diagnosis of deep venous thrombosis in the lower limb, was compared with conventional ascending phlebography in 69 patients. The results showed a diagnostic sensitivity of 97% and a diagnostic specificity of 50% giving an overall agreement of 73% between the methods. The low diagnostic specificity of thermography was to be expected, since any inflammatory reaction, whatever the cause, will give a rise in the skin-temperature. The high sensitivity shows that thermography is useful as a screening method. In the present material thermography could have prevented 25 per cent of the phlebographies.
接触式热成像法是一种用于诊断下肢深静脉血栓形成的非侵入性廉价检查方法，对69例患者进行了该方法与传统上行静脉造影的比较。结果显示诊断敏感性为97%，诊断特异性为50%，两种方法的总体一致性为73%。热成像法诊断特异性低在意料之中，因为任何炎症反应，无论病因如何，都会导致皮肤温度升高。高敏感性表明热成像法作为一种筛查方法很有用。在本研究资料中，热成像法可使25%的静脉造影检查得以避免。
