Explanation of MPI magnetic resonance terminology

Hello! T1WI, T2WI, FLAIR, DWI are the names of the weighted images of MRI scans. As long as you understand the same part, the images displayed by these four weighted images are different, the focus of reading is different, and the functions are also different.

Tra and SAG are terms for different cross-sectional directions of the swept surface, Tra is a cross-sectional section, and the image that comes out is a horizontal section, that is, the image that is cut out horizontally, and SAG is a sagittal position, and the image that comes out is an image cut out vertically.

Landlord, you are too picky, you don't give points!

You are writing all the wrong questions, magnetic resonance should be abbreviated as MRI=magnetic resonance imaging

The following are abbreviations, which are explained as follows:

tra=transverse, transverse face.

t1w1=t1 weighted, t1 weighted.

t2w2 omitted.

flair=fluid attenuated inversion recovery, the return recovery sequence of the pressure signal.

DWI=diffusion weighted imaging.

sag=sagittal sagittal plane.

As for the specific meaning of these terms, you still need to read more professional books to figure it out. Or, you sent me a message, let's talk about it in depth.

Interpretation of NMR.

1) [nuclear magnetic resonance;Abbreviation NMR] A phenomenon in a static magnetic field that exhibits a large number of atomic nuclei that absorb energy from a radio frequency field of certain characteristic frequencies (2) [Magnetic Resonance].

As a result of spatial quantization, the response of atoms to certain discrete radiation frequencies is roughly solved.

Explanation of the kernel Nucleus é the part of the fruit that is hard and contains the kernel: the peach pit . Apricot kernels.

Like the nucleus of the thing : the nuclear cell. Nucleic acid.

Core (center). Tuberculosis. Nucleus.

Nucleon. Nuclear reaction. Nucleus**.

Carefully compare and examine: approve. Auditing.

Verify. Accounting. Check.

Detailed and correct cracking: its straightforwardness, its matter Explanation of resonance When two objects with the same vibration frequency vibrate, when one vibrates, it causes the other object to vibrate The relationship between several objects that can interact with each other to convey vibration through the medium Explain in detail the relationship between two objects with the same vibration frequency, when one of them vibrates, it causes the other object to vibrate, this phenomenon is called resonance.
