which is why we call it multiplanar and so if we were to look at a simple thing like a simple image like an e so we always like our Anatomy image so that's our plane t1 because fat is beautiful and it actually allows us to see everything really well and it looks like what we're actually accustomed to seeing and so we do a t1 sequence and would also look at a t2 sequence or a t2 fat's at sequence and what that actually allows us to do is on a t2 fat's at we actually go matte so that's fat saturation yeah so a t2 fat saturation what we're doing is we're taking t2 so now we're t2 looks at two things so fat and water and then we actually suppress the fat so really all we're seeing is water and why that's most interesting is because edema so when there's something going wrong in the body almost anywhere edema happens it's like if you bang your hand and it swells up that swelling is edema you injure your knee it swells up that's edema and so if you actually bang the bones on your knees so you've actually injured the cartilage you're gonna get edema happening in the ends of the bone as well as in the cartilage so that's why the t2 with saturation or removing the fat signal becomes so powerful because it effectively now turns into a edema imager and when we know when there's edema there's a problem and that's kind of a simple concept in MRI that is quite often lost but it's very very important
