It’s all about FAT and also WATER
The two basic types the MRI pictures are T1-weighted and also T2-weighted images, often referred to as T1and T2images.
You are watching: What does t1 and t2 mean
The time of radiofrequency pulse sequences offered to make T1 photos results in pictures which to mark fat tissue within the body.
The time of radiofrequency pulse sequences supplied to do T2 photos results in pictures which highlight fat AND water within the body.

So, this makes things easy to remember.
T1 images – 1 tissue kind is shining – FAT
T2 images – 2 tissue types are glowing – FAT and WATER

T1-weighted image – Anatomy (spine)T1 images deserve to be believed of together a map of proton energy within fatty tissues the the bodyFatty tissues insmashville247.netrporate subcutaneous fat (SC fat) and also bone marrow the the vertebral bodiesCerebrospinal fluid (CSF) smashville247.netntains no fat – for this reason it appears black top top T1-weighted imagesT2-weighted picture – Anatomy (spine)

T2-weighted picture – Anatomy (spine)T2 images are a map of proton power within fatty AND water-based organization of the bodyFatty tissue is identified from water-based organization by smashville247.netmparing with the T1 images – anything the is glowing on the T2 images yet dark top top the T1 photos is fluid-based tissueFor example, the CSF is white ~ above this T2 image and also dark top top the T1 image above because that is smashville247.netmplimentary fluid and smashville247.netntains no fatNote that the bone smashville247.netrtex is black smashville247.netlor – it gives off no signal on one of two people T1 or T2 images because it smashville247.netnsists of no free protonsT1 weighted picture – Pathology (spine)
