Temporal bone CT scan side skull fracture. In addition to the confirmation of the ossicles, such as fractures and dislocations, temporomandibular facial fractures, deformities surgery helps to establish a science plan. Cochlear implant surgery has been performed in the state before and after identifying purposes. Test methods are being implemented by the Conventional direct axial and Direct coronal scan, the basic method of Temporal bone CT. Helical scan is a fast Volumetric data obtained compared with the Conventional scan, the patient reduced the dose, and there are some advantages, such as reduced Beam hardening streak artifacts caused by dental fillings. This study is a comparative analysis by dose reduction for patients with a dose according to the conventional scan method and then effective from 2015 by helical scan method performed in 2014 through the retrospective survey, which was then optimized for the purpose of inspection.
전산화 단층촬영을 이용한 상악후부 치아와 상악동 저부와의 거리 측정
김영기,양국진,정현수 인제대학교 1993 仁濟醫學 Vol.14 No.1
상악동과 상악후부 치아와는 밀접한 관련이 있음이 잘 알려져 있다. 하지만 실제 각 상악후부 치아와 상악동 저부와의 거리를 측정한 예는 거의 없다. 저자들은 관상 전산화 단층촬영을 이용하여 상악후부 치아와 상악동 저부와의 거리를 측정하였다. It is well known that the maxillary posterior teeth are close to the floor of the maxillary sinus. But the distances between them were evaluated rarely. We measured the distances between the maxillary posterior teeth and the floor of the maxillary sinus with the coronal CT scan.
