I love how it's just technical enough so that you understand the fundamentals of what's going on, but he also does a great job of explaining how things work in a simple and easy to digest manner. Definitely have a better grasp as to what goes on now.

I visited the Siemens Healthcare factory in Erlangen, Germany as part of our Bachelor's Studies. The amount of cutting-edge engineering and technology that they have in order to manufacture these MRI machines is astonishing. Simply one of the "craziest" technology companies out there.

I've explained the functioning of an MRI in a basic form since they were first about in 1980, but this really blows that explanation out of the water and expands it way beyond - brilliant!

Signal in MR images is high or low (bright or dark), depending on the pulse sequence used, and the type of tissue in the image region of interest. The following is a general guide to how tissue appears on T1- or T2- weighted images. Dark on T1-weighted image: increased water, as in edema, tumor, infarction, inflammation, infection, hemorrhage (hyperacute or chronic) low proton density, calcification flow void . Bright on T1-weighted image: fat subacute hemorrhage melanin protein-rich fluid slowly flowing blood paramagnetic substances: gadolinium, manganese, copper calcification (rarely) laminar necrosis of cerebral infarction . Bright on T2-weighted image: increased water, as in edema, tumor, infarction, inflammation, infection, subdural collection methemoglobin (extracellular) in subacute hemorrhage.. .. Dark on T2-weighted image: low proton density, calcification, fibrous tissue paramagnetic substances: deoxyhemoglobin, methemoglobin (intracellular), iron, ferritin, hemosiderin, melanin protein-rich fluid flow void

For now all I can do it's wait and see since brain surgery it's not an option for me. Over all good video🤗 I kinda of got it

Nuclear Magnetic Resonance - apparently that word was scary, so they chose the term MRI instead.

@8543960 3 жыл бұрын

Its origin lies in a technique chemists use to help determine the structure of organic molecules called Nuclear Magnetic Resonance Spectroscopy. It uses a superconducting magnet (back in the early days of the technique, just strong ordinary magnets) and radio frequency light. The physics of NMR and MRI is exactly the same, the spin flip of a proton when immersed in a magnetic field. The two techniques just look at different aspects of it. NMR is more concerned about the absorption of radio frequency by nuclei in the magnetic field whereas MRI I believe is more concerned with the amount of time the nuclei spend in their excited states.

Thanks for the explanation. I'd like to point out that particles are not spinning. Spin is a fundamental quantum property of the proton and has nothing to do with it spinning.
