Introduction to MRI: Basics 2 - T1 and T2 relaxation, what tissues look like

[@rajdeepsamadder2000]

as a MBBS final year student its very helpful to me..!!! no body teach these in our college... keep putting these kind of videos sir!! 🙏🙏🙏🙏🙏🙏

[@rajdeepsamadder2000]

@cryptomMRIyeah.. it's college of medicine and sagore dutta hospital, it's in Kolkata, INDIA..

[@rajdeepsamadder2000]

@cryptomMRI i see, how many medical schools in your country?? Both government and private…

[@laurenbryant9616]

Learning more from your videos than I do in class. They are so easy to understand. Thank You

[@denissitasc]

Thank you so so much , I couldn’t understand the physics of MRI , but now I have a pretty good idea of the basic and a little more , please continue doing videos , it really help me and others. I definitely subscribe

[@BayAreaLakers]

Man, this is great You're answering all of my questions

[@makeaday13]

This was awesome and super helpful!! Definitely watching this during MRI school. Thank you!👏

[@gissellev.18]

I have my board exams this spring and your videos have helped me so much to review! Thank you!

[@rajdeepsamadder2000]

r these asked in mbbs board exams??!🤷‍♂🤷‍♂

I’m a first year medical student and we have this topic 😭

I’m a first semester MRI student and this just made a lot of things click for me. Thank you soo much!

[@HrPedrosak]

Great stuff. Keep em coming 👍

[@michaelsauder]

That was a heavy load. Thanks for the video. Very helpful and interesting

[@imhereforyou1900]

Your videos are all very easy to understand. Thank you so much, hope you keep doing great. They're really help me a lot 🥰 P/s: do you make video about Ultrasound too?

[@navigatingradiology]

There are two on Doppler ultrasound. On our Patreon we take requests for content and can answer specific questions.

[@AtikaZainab1085]

11:21 A doubt here... If we're detecting the signal through the XY component, then why would water not produce a larger signal than fat? Fat has more of the Z component than XY, right?

[@deepaksanwal3602]

Please upload a video on MRI spine..🙏🏻

[@charlotteee931]

Love your videos! Can't wait for more^^

[@ruthviadriana5678]

Thank you

[@MrSlawkie]

Great when can we expect next part?

[@navigatingradiology]

Next few days!

[@ukdhillon]

Where’s part 3?

[@dhurghamfadhil]

Could use this technique to separate multi-chemical species?

[@barrackjtt]

Easy to understand

[@gena.9564]

What does a hypo intense signal in the spinal cord on T1 and T2 mean?

[@imanetihlat2419]

Thanks 😊

[@adibasistudypoint981]

Plz upload next video of this series..I wanna join to Patreon but paying option is not suited can be there other option other than PayPal and credit card.

[@BedeliaMikk]

I dont understand why water is dark on T1 and bright on T2 :-(

[@TC-dw6wg]

It has to do with its relaxation times for T1 & T2. T1: Dark because it hasn’t enough time to fully recover longitudinal relaxation. We haven’t received enough (large) signal back so it’s dark. T1 time is long for water (fluids). T2: bright because it has decayed sufficiently from horizontal plane for T2 relaxation of that tissue. We receive a high signal back and that’s why it’s bright. T2 times are longer on some sequences which allow greater signal…bright image Water has a long TR & TE T1 images TR short TE short T2 Images TR long TE long Hope this made some sense to you.

[@rianshala3565]

How does fat and water appear in T2* decay?

[@Ram-iu5el]

The net magnetization will also be rotating until T2 relaxation happens. That is not brought out here... the diagrams are therefore schematic and inaccurate...

Next video plz

[@Ram-iu5el]

The guy does not even emphasize the "resonance" part...
