(영어/영문/English) The parameter that influence the image contrast of the organization 1. spin density 2. T1 relaxation time 3. T2 relaxation time The most important factor that affects the MR signal is the spin density. Strictly speaking, it is most important how the hydrogen atoms are bound in the molecule, not the existence of the spin. However, since the Z-axis component of the net magnetizatio..

(영문, 영어, English) The protons with magnetic dipoles are divided into protons of low energy level precessing in the same direction with respect to the magnetic field applied from the outside, and protons of high energy level precessing in the opposite direction. That is, there are spins in the two orientations, parallel (also known as spin up) and antiparallel (spin down). At this time, more will..

(영어, 영문, English) Low-frequency radio waves penetrate the tissue and reflect back off magnetized spins within the object. In MRI, an RF wave, or an RF pulse, is transmitted into the patient, and a signal is received from magnetized spins (protons) in the body. 1. If spining and unpaired protons are placed in an external magnetic field, they will lined up with that magnatic field. (It's the time ..

(영문, 영어, English) MRI is an abbreviation for magnetic resonance imaging. It is a non-invasive way to view organs and tissues within the body. MRI uses a strong magnetic field, radio waves and computing program to create detailed internal images of the body. We can get cross-sectional image like sagital images, coronal images and axial images of organs, tissues, bones, and other structures inside..

안녕하세요 오늘부터 티스토리 블로그를 시작하게된 방사선사나라 입니다. 저는 제 전공 분야 공부를 위해서 블로그를 시작하게 되었고요 티스토리의 제목처럼 방사선사(radiographer)가 궁금해할만한 내용들 위주로 포스팅할 예정입니다. (MRI, 일반촬영, 해부학, 의학용어 등) 이왕이면 전공에 대한 모든 글을 국문과 영문으로 올릴 예정이니 많이 봐주시고 응원해주세요~
