This is part of a series of shorter, more digestible videos that are designed to introduce you to MRI in general, with an emphasis on body MRI. See the playlist to watch the videos in order.
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
Learning more from your videos than I do in class. They are so easy to understand. Thank You
Man, this is great You're answering all of my questions
Great stuff. Keep em coming 👍
This was awesome and super helpful!! Definitely watching this during MRI school. Thank you!👏
That was a heavy load. Thanks for the video. Very helpful and interesting
Love your videos! Can't wait for more^^
I’m a first semester MRI student and this just made a lot of things click for me. Thank you soo much!
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!!
🙏🙏🙏🙏🙏🙏
Excuse me Where do you study please?
@@cryptomMRIyeah.. it's college of medicine and sagore dutta hospital, it's in Kolkata, INDIA..
@@rajdeepsamadder2000 awesome, here in my hospital in Iraq in my city we have Indian team works in radiotherapy department, I'm radiology technologist
@@cryptomMRI i see, how many medical schools in your country?? Both government and private…
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?
There are two on Doppler ultrasound. On our Patreon we take requests for content and can answer specific questions.
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.
Could use this technique to separate multi-chemical species?
Please upload a video on MRI spine..🙏🏻
I have my board exams this spring and your videos have helped me so much to review! Thank you!
r these asked in mbbs board exams??!🤷♂🤷♂
I’m a first year medical student and we have this topic 😭
@@lajimolala5647 which subjects u r tought in 1st yr? In India we have biochemistry , physiology and anatomy 👍
@@rajdeepsamadder2000 in Iraq we have anatomy, biology, histology, physiology, embryology, and medical physics 🥲
Easy to understand
What does a hypo intense signal in the spinal cord on T1 and T2 mean?
Thanks 😊
Thank you
How does fat and water appear in T2* decay?
Great when can we expect next part?
Next few days!
Where’s part 3?
I dont understand why water is dark on T1 and bright on T2 :-(
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.
Next video plz
The net magnetization will also be rotating until T2 relaxation happens. That is not brought out here... the diagrams are therefore schematic and inaccurate...
The guy does not even emphasize the "resonance" part...
