[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 weighted image (T1WI) - T1 강조영상
(영어/영문/English) In the process of recovering the spins of the human body (recovering to the original state of the longitudinal magnetization) after receiving energy, the T1 weighted image is the image of the difference in T1 recovery time between tissues. The T1 weighted image is obtained by appropriately adjusting TR and TE. (the extrinsic factors representing the contrast of the image) The mos..
[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..
