医学影像在口腔颌面肿瘤的临床诊断中占重要地位,新的成像技术问世以来,医学影像从传统的X线检查跃进到影像信息数字化、电子计算机辅助和图像重建的新途径。当今CT已被广泛应用。MRI、ECT正在开发,高频声像诊断已被公认为一种具有实用价值的检查方法。新成像技术的应用实践证明,任何一种检查技术都具有各自独特的优势和局限性,因而各种影像技术在诊断工作中应起相辅相成的作用;合理选用并将各种成像技术合理地组合起来使其发挥更大的作用,以下陈述几种常用的成像技术在诊断口腔颌面 Medical imaging plays an important role in the clinical diagnosis of oral and maxillofacial tumors. Since the advent of new imaging techniques, medical imaging has leapt from the traditional X-ray examination to a new way of digitizing image information, computer aided and image reconstruction. Today's CT has been widely used. MRI and ECT are under development. High-frequency audio-visual diagnosis has been recognized as a practical method of examination. The application of new imaging technology has proved that any one of the inspection techniques has its own unique advantages and limitations, and therefore a variety of imaging techniques in the diagnosis should play a complementary role; reasonable selection and a variety of imaging techniques reasonable combination To play a greater role, the following statement of several commonly used imaging techniques in the diagnosis of oral and maxillofacial
