What is T1 and T2 in MRI?

LikeAnswersShare

T1-weighted images are produced by using short TE and TR times. The contrast and brightness of the image are predominately determined by T1 properties of tissue. Conversely, T2-weighted images are produced by using longer TE and TR times. ... CSF is dark on T1-weighted imaging and bright on T2-weighted imaging.

It's all about FAT and WATER The two basic types of MRI images are T1-weighted and T2-weighted images, often referred to as T1 and T2 images. The timing of radiofrequency pulse sequences used to make T1 images results in images which highlight fat tissue within the body.

I presume these are vertical sections As other plain is axial one
