T2 Weighted image contrast state is approached by imaging with a TR long compared to tissue T1 (to reduce T1 contribution to image contrast) and a TE between the longest and shortest tissue T2s of interest.</td></tr><tr><td><a href="http://tx.fhir.org/r5/ValueSet/DCM#DCM-113043">113043</a></td><td>Diffusion weighted</td><td>Values are derived by calculation of the diffusion weighting.</td></tr><tr><td><a href="http://tx.fhir.org/r5/ValueSet/DCM#DCM-113041">113041</a></td><td>Apparent Diffusion Coefficient</td><td>Values are derived by calculation of the apparent diffusion coefficient. This concept may be used for the diffusion coefficient of various different models, e.g., mono-exponential (ADCm), kurtosis (ADCk), stretched-exponential (ADCs).The &quot;apparent&quot; appellation is because the diffusion images from which the ADC is computed may also be affected by T2 contrast (T2 &quot;shine-through&quot;), so this concept is distinguished from a &quot;pure&quot; diffusion coefficient that is not so affected.</td></tr><tr><td><a href="http://tx.fhir.org/r5/ValueSet/DCM#DCM-110816">110816</a></td><td>T1 Weighted Dynamic Contrast Enhanced MR Signal Intensity</td><td>Signal intensity of a T1 Weighted Dynamic Contrast Enhanced MR image. A T1 Weighted Dynamic Contrast Enhanced MR image reflects the dynamics of diffusion of the exogenous contrast media from the blood pool into the extra vascular extracellular space (EES) of the brain at a rate determined by the blood flow to the tissue, the permeability of the Brain Blood Barrier (BBB), and the surface area of the perfusing vessels.</td></tr></table></li></ul></div>
