    2)단층영상을 얻을 수 있다.

  • 단점 1) 다양한 각도의 영상을 얻는데 한계

    2) 연부조직의 해상도가 낮고 동태적 검사에 부적합

    3) 병리조직학적 구분에 한계가 있다.

    4) 조영제를 사용하여야 한다.

  • 적응증: 부신, 신종물, 신외상, 신이식, 선천성기형, 방광암, 후복막강 및 전립선암의 병기 결정 등


  • 조직의 자기성을 이용하여 영상을 얻는다.

  • 장점 1)no radiation

    2)no contrast media, no bowel preparation

    3)great flexibility for imaging in many planes

    4)better information about soft tissue

  • 단점 1) expensive, longer time than CT
