초록
목적: 수의 영상진단을 위하여 3T 능동차폐형 자석을 장착한 전신용 자기공명영상장비를 이용하여 고해상도의 개 두뇌, 척추, 복부 및 골반 자기공명영상을 획득하였다. 대상 및 방법: 128 MHz의 공명주파수를 갖는 RF코일을 사용하여 정상 개 및 환축으로부터 스핀에코와 고속 스핀에코 펄스시퀀스를 적용하였다. 전형적인 펄스시퀀스의 매개변수는 512
For veterinary imaging diagnosis, we obtained MR images of the canine brain, spine, kidney and pelvis from 3T MRI system which was equipped with the world first 3T active shield magnet. Spin echo (SE) and fast Spin Echo (FSE) images were obtained from the canine brain, spine, kidney and pelvis of normal and sick dogs using a homemade birdcage and transverse electromagnetic (TEM) resonators operating in quadrature and tuned to 128 MHz. In addition, we employed a homemade saddle shaped RF coil. Typical common acquisition parameters were as follows: matrix=512
