浸潤と転移の早期画像診断−超音波口腔内走査における舌癌の浸潤先端と頸部リンパ節転移へのCT灌流画像の応用について−

Abstract

According to the literature regarding the intraoral ultrasonography application for the diagnosis of tongue carcinoma, a tumor invasion area had been demonstrated as hypoechoic compared with the surrounding structure. However, especially with the recently released high-resolution intraoral probe, histopathological invasion front did not always correspond with the deepest margin of the hypoechoic area because the invasion front always tended to be affected by various degree of inflammatory reaction.
