Method using image enhancer and cone-beam CT imaging technology to detect cracked-tooth crack

The invention relates to a method using an image enhancer and the cone-beam CT (CBCT) imaging technology to detect a cracked-tooth crack. The method is characterized in that the enhancing contrast medium meglumine diatrizoate to enhance the crack, and cone-beam CT imaging development is performed rapidly after the contrast medium seeps into the crack so as to judge the position and depth of the cracked-tooth crack and distinguish the crack from a linear low-density artifact formed by root-canal filler. By the method, the accuracy, sensitivity and specificity of tooth cracking diagnosis using the CBCT can be improved effectively, and the cracked-tooth crack positioning accuracy of the CBCT can be increased. 本发明涉及一种利用影像增强剂及锥形束CT(CBCT)成像技术检测隐裂牙折裂纹的方法，其特征在于：利用增强造影剂泛影葡胺对裂纹进行增强，待造影剂渗透进入裂纹内，迅速通过锥形束CT成像显影，从而判断隐裂牙裂纹的位置，深度，并与根管充填物形成的线状低密度伪影相鉴别。通过上述方法的实施，能够有效提升CBCT诊断牙隐裂的准确性，灵敏度和特异性，并提高CBCT对隐裂牙折裂纹的定位准确率。
