Do you we need minimum and maximum values? for SI mean, area, circumference, SI mean, SI min/max?

T1 mapping in CMR, elevated T1 values  pointing to edematous tissue.

2 types of myocardial fibrosis - 1) interstitial , 2: replacement fibrosis (post MI), interstitial fibrosis subtypes - reactive and infiltrative fibrosis. Reactive: HT, DCM, volume/pressure overload; infilstrative: amyloid, Anderson Fabry

Diseases characterized by diffuse myocardial fibrosis cannot be evaluated by LGE since there are no reference regions of normal myocardium (Rosario J. Perea et al).

T1 mapping:

1. A T1 map of the myocardium is a parametric reconstructed image
2. Each pixel's intensity directly corresponds to the T1 relaxation time of the corresponding myocardial voxel.
3. Quantification of diffuse myocardial fibrosis.
4. Native T1 reflects myocardial disease involving the myocyte and interstitium.
5. The use of gadolinium allows measurement of the extracellular volume fraction, reflecting interstitial space.

Do we need timepoints for the T1 measurement or just the point in time of the final assessment?

Does Cardiac Motion correction need to be indicated? If yes, does the type need to be indicated (such as the modified LL (MOLLI) sequence)?  If yes, should this be reflected on each result? (Alana/Jon/Diane - I am considering a "Cardiac Motion Correction Indicator" NSV)

Do we need a postcontrast indicator since those measurement differ? or is that what the terms "native T1" (no contrast) and "post-contrast T1" (after contrast) mean?

Three is a "gold" standard noted as the "T1 mapping based on the acquisition of single images by a T1 turbo spin-echo sequence". It is noted as the ultimate T1 mapping method. Does the method need to be called out by what kind of acquisition sequence was used?

For the location does the intracellular compartment need to be noted? (myocytes, fibroblasts, endothelial cells, smooth muscle cells)

Does the cardiac phase for the specific T1 segment need to be noted? (atrial systole-diastole; isovolumentric contraction-diastole; rapid ejection-systole; reduced ejection-systole; isovolumetric relaxation-diastole; rapid ventricular filling-diastole)

Is it important to record the "MRI scanner type" (Avanto, Siemens; Best, Philips; Acheiva, Philips), the "reception coil" (16-channel; 32-channel), "the T1 mapping sequence" (MOLLI; ShMOLLI)
