[MRI] (영/한) <SUMMARY> T1WI, T2WI, PDWI / <요약> T1강조영상, T2강조영상, PD강조영상
(영어/영문/English) 1. T1WI (T1 weighted image) To get a T1WI, a short TR and short TE are required. The clinically appropriate TR is 350~750ms, and the TE is 10~30ms. It is easy to see the anatomical structure and is mainly used in contrast imaging. 2. T2WI (T2 weighted image) To get a T2WI, long TR and long TE are needed. Clinically appropriate TR is over 2500ms and TE is 60~120ms. It is easy to i..
[MRI] (영/한) T1 relaxation time and T2 relaxation time of tissues - 각 조직의 종축 이완시간과 횡축 이완시간, 영향인자
(영어/영문/English) 1. T1 relaxation time (Longitudinal relaxation time) T1 relaxation time varies depending on the tissue. It depends on the shape of the nucleus, the strength of the magnetic field, the temperature, the viscosity of the spin, the size of the molecule, and the presence of paramagnetic ions or molecules. For example, the energy release of the excited spin through the exchange of ener..
