Introduction to Abdominal MRI: Background, Pulse Sequences, Normal Appearance (Body MRI, Abdo MRI)

Access our MRI and CT case-based courses at navigatingradiology.com, which include fully scrollable cases, walkthroughs of imaging findings, and comprehensive reviews of basic and more advanced imaging studies.
The background you need to understand before looking at Abdominal MRI, and prior to any Body MRI rotation.
Basic Physics (2:03), Common tissues (22:54)
Pulse Sequences 27:07 (Gradient Echo, Spin Echo, TE/TR and tissue contrast, Fat saturation: 41:12, DWI: 46:38)
Common Pulse Sequences in Abdominal MRI 55:29 (Fast T1W and T2W imaging, in and out of phase, MRCP)
Typical Abdominal MRI Protocol 1:14:12
Normal Abdominal MRI Scan 1:17:08
Abnormal Abdominal MRI (Case) 1:27:52
Future videos will review Liver, Pelvic, and Prostate MRI.
For in depth physics reading, I suggest mriquestions.com

You sir, made everything so clear. I almost gave up couple of times but you asked me to hang on and I am glad I did. Thanks again.

Thank you for patiently delivering the basics of MRI Abdomen. It's rich

[@emadid3]

Thanks a lot for this accurate while simple video lesson, it's excellently made. Please keep updating this MRI course! / A 2nd year italian resident in Radiology /

Good stuff, thx to all who make these vids available.,,especially the presenter-doc who has made good use of his Communication 101 classes. And thx for the time annotation..very helpful.

[@oyimanemmanuel2407]

Thanks so much for such an educative session..

[@fuatdede4500]

Thank you so much for such a beautiful and satisfying presentation. Do you plan to make a separate presentation on whole body MRI techniques used in PET/MR for nuclear medicine physicians? Best wishes.

[@dr.md.shalahuddin2185]

Just an awesome outstanding delivery.
Can u plz specifically mention where MRI Abdomen is necessary instead of CT. What extra info can an MRI provide?

[@bhupalbisht5150]

Excellent.

Very informative...

Go on we need more doctors to help us with MRI😊

[@RD2564]

Love your left handed coordinate system. A lot of you MRI / doctor guys do that, which is fine, the math can be made to adapt, maybe it's an MRI industry standard or something, but it's interesting to me because they were very careful to only ever use a right hand coordinate system in math, science and engineering courses when I was in engineering school way back in the good old days, the 80's. That way all the equations were same in all the text books. We even only ever talked about one sign convention version of the 1st law of thermodynamics back in those days. Good times, good times ...

Hey Tony!

[@lostproton4916]

A little correction. It is not the RF pulse that makes the proton precess. Protons start precessing once they get into the B0 field. The RF pulse just puts the already precessing protons in phase.

[@ayoubwani259]

Sir kindly have the same MRI regarding brain/spine

Blood: could you please add examples? I. E. Hyperacute vs chronical bleed.

[@taurus4495]

Is that a moss code on the line that shows the video progress?

[@Gragon]

Hello. Question.
We dont really measure the longitudinal relaxation because like you said we measure signal on xy plane. So we measure t1 relaxation by measuring decreasing signal on xy plane.
The same signal is composed of precessing atoms and when they loose precession the horizontal magnetization also decreases.
How do we diferenciate t1 recovery from t2 relaxation if both processes are measured on xy plane?

[@lostproton4916]

1. t1 relaxation or more precisely the decay of the Net Magnetization Vector along B0 happens, well, along B0, so the very small magnetic vector cannot be measure next to the big B0 magnetic vector. Bit like pissing into a big river, can you register your piss? No, because it is minuscule compared to the river.
2. t1 is measured indirectly. I don't know details, though.

more than thanks !! isn't fair to see this video and just not to comment. year 1 RAD. resident. east africa

[@patriciascott4323]

Hi an ultrasound showed a fatty liver so a MRI was ordered. What is type of abdominal MRI is better 1.5 T or 3.0 T considering chemical shift artifacts, SAR, RF field inhomogeneity, magnetic susceptibility. I would appreciate your opinion. Thanks
