T1 vs T2 weighted MRI images: How to tell the difference

I've created a radiology physics question bank. Check it out here 👉 www.radiologytuts.com/courses...
In this video I share with you a simple trick to tell the difference between T1 and T2 weighted MRI brain images. It can be confusing when telling T1 vs T2 MRI images apart. But it really shouldn't be.
After this video you will know how to tell the difference between T1 and T2 MRI weighted images.

You helped a lot of confused med students, a HUGE thank you

[@treasurennaji4518]

Came as a confused med student and this video has helped a lot!!!!❤️

[@kulanchandrasekaran4462]

Your advise regarding seeing the gray and white matter first, rather than the CSF, is very important and valuable. Thanks for the time and effort you have spent in teaching us.
The Q and A format is very valuable, and the only way to reinforce learnt material. It requires a lot of extra time and effort, additional thanks for that.
Very valuable channel I discovered by serendipity on TH-cam, subscribing now.

Hey good luck with your final exam with the ARRT. So that means you are done with clinical and internship and the whole MRI program. Was it a two years program too? was it hard? what was the hardest part of the program? the hardest subject i mean ? thank you, any advices i will appreciate as a me too i will be starting my classes for MRI tech this October and i am super excited but also super nervous. Thanks again....and wishing you the best scores for your ARRT examination. (:

Can you please help urgently with the planning since I don’t know why radiologist prefers planning with genu and splenium of corpus callosum or anterior posterior commissure please explain why in mri planning

[@neuroxplorein]

One of the best explainations for mastering recognizing these sequences! Could you please do a similar one for recognizing a GRE vs DWI image, and also address why does a T2 sometimes look really crisp with white CSF and other times the contrast looks duller with light gray CSF?
QUESTION: I thought a DWI is a FLAIR without a scalp, but the image shown here was bright CSF. Is that really a DWI? Is that because of a lower b-value?

[@NURATify]

Thank you for this insightful video. I wish to know how to calculate the "weight" of the MRI TI, T2, DWI, Flair or any other format. Is there a code or toolkit that can do this easily. Thank you as you respond positively.

[@radiologytutorials]

Hi Yinka. The "weighting" of an image refers to the actual sequence of electromagnetic forces we apply in the scan. It is not a specific value we can calculate. There are different types of sequences we use and varying two values (TE and TR) will determine the weighting. Hope that makes some sense. Watch my DWI vs ADC video. It may help understand a bit better. Thanks for watching the videos 🙏🏻

[@anniesshenanigans3815]

do you mean the normal range for these type of images? There are lots of variants on the images from TR, TE, TI, flip angles and also the strength of the magnet. For instance a T1 "image" needs short tr and short te, T2 image longer tr and te, but a proton density image has a long tr and short te. Most images that are sent to rads have some of the values projected on the image, depending on the manufacturer of the scanner, and those values are determined by either the Radiologist (prearranged), or the tech that did the scan or in most cases a collaboration of the lead Radiologist and the applications specialist. (that is what I do).
