What is contrast in MRI used for?

Contrast MRI is a highly sensitive and specific diagnostic test, capable of providing, compared to conventional MRI, clearer and more detailed images of the internal structures of the human body (blood vessels, organs, tissues, etc.).

How do you get a T2-weighted image?

To obtain a T2-weighted SE sequence, a long TR associated with a long TE is used. The efficiency of T2 depends on various factors such as the size of the molecules: the smaller the molecule, the longer the desynchronization time; large molecules have shorter T2s. Water therefore has a long T2.

What does fat suppression mean?

Imaging with fat suppression In practice, if the object to be examined contains both water hydrogens and fat hydrogens, the technique, for the purpose of image acquisition, is able to "zero" the NMR signals coming from the fat .
