Sonography has proved superior to CT and MRI for imaging T1 or T2 carcinomas of the oral cavity and base of the tongue. However, in examining the anterior half of the tongue and the floor of the mouth problems arise due to absorption of sound by the mandible and air inclusion. Ultrasound examination can be performed end-orally by means of a miniaturised transducer. End-oral sonography produces images of the anterior parts of the tongue and the floor of the mouth without artefacts. This method is superior to conventional transcutaneous sonography for this region.
超声检查已被证明在口腔和舌根的T1或T2期癌成像方面优于CT和MRI。然而，在检查舌前半部分和口腔底部时，由于下颌骨对声音的吸收和空气的存在会出现问题。超声检查可以通过小型化换能器经口腔内进行。经口腔内超声检查可产生舌前部和口腔底部的图像而无伪像。对于该区域，这种方法优于传统的经皮超声检查。
